Description

Technical Field

[0001] This invention relates to the field of inkjet printing technology, and in particular to a solid color transfer printing method, apparatus, equipment, and storage medium. Background Technology

[0002] Digital printing involves inputting a pattern digitally into a computer, which then processes the data to generate print data that the printhead can recognize. This print data controls the printhead to spray ink onto the substrate, forming text or patterns, thus producing the printed product. When dyeing textiles, traditional printing methods are time-consuming, labor-intensive, and environmentally polluting. Current digital inkjet printing methods, on the other hand, often result in uneven ink color due to the printhead directly spraying ink onto the textile.

[0003] To avoid the above problems, the market now needs an inkjet printing method that can achieve uniform ink printing and high-efficiency printing. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a solid color transfer printing method, apparatus, equipment, and storage medium to solve the problems of high cost, low efficiency, and uneven dyeing in existing textile dyeing technologies.

[0026] The first preset data volume is obtained based on the amount of data to be printed and the size of the ink droplets.

[0027] Monitor the amount of print data generated by the printhead;

[0028] When the amount of printed data from the printhead is a first preset amount, the first ink state reaches the first preset state.

[0029] A second ink adjustment signal is generated, and the four colors of ink in the CMYK ink cartridge are controlled to enter the second ink cartridge according to the second ink adjustment signal to generate the preset color ink. The CMYK ink cartridge includes a C cartridge containing green ink, an M cartridge containing magenta ink, a Y cartridge containing yellow ink, and a K cartridge containing black ink.

[0031] Obtain the second preset data volume according to the preset printing requirements;

[0032] When the amount of printed data from the printhead is the second preset amount, the first ink state reaches the second preset state.

[0033] The first ink cartridge is controlled to stop supplying ink to the printhead, while the second ink cartridge is controlled to supply ink to the printhead.

[0034] Preferably, the first ink cartridge and the second ink cartridge are connected by a linkage device to alternately supply ink to the printhead.

[0035] Secondly, embodiments of the present invention provide a solid color transfer printing apparatus, the apparatus comprising:

[0036] The first printing module is used to monitor the ink status of the first ink cartridge during the printing process, which is recorded as the first ink status. When the first ink status reaches the first preset status, the preset color ink is generated in the second ink cartridge.

[0042] Fourthly, embodiments of the present invention provide a storage medium storing computer program instructions, which, when executed by a processor, implement the method of the first aspect described above.

[0043] In summary, the beneficial effects of the present invention are as follows:

[0044] The solid color transfer printing method, apparatus, device, and storage medium provided in this invention embodiment include: S1: monitoring the ink state of the first ink cartridge during the printing process, denoted as the first ink state; when the first ink state reaches a first preset state, generating the preset color ink in the second ink cartridge; S2: when the first ink state reaches a second preset state, controlling the first ink cartridge to stop supplying ink to the printhead, while simultaneously controlling the second ink cartridge to supply ink to the printhead; S3: monitoring the ink state of the second ink cartridge during the printing process, denoted as the second ink state; when the second ink state reaches the first preset state, generating the preset color ink in the first ink cartridge; S4: when the second ink state reaches the second preset state, controlling the second ink cartridge to stop supplying ink to the printhead, while simultaneously controlling the first ink cartridge to supply ink to the printhead.

[0045] S5: Repeat steps S2 to S4, and control the printhead to spray the preset color ink onto the transfer roller to form a transfer image and control the transfer roller to transfer the transfer image onto the substrate until the transfer is complete. The CMYK ink is alternately mixed within the first and second ink cartridges and supplied to the printhead. This process ensures thorough mixing within the sealed containers of the first and second ink cartridges, generating a uniformly colored preset color ink. The continuous ink supply to the printhead guarantees uninterrupted ink ejection, maximizing printing efficiency. In the first preset state, the CMYK inks are controlled to enter either the first or second ink cartridge to generate the preset color ink, ensuring uniform color and preventing oxidation or aging due to prolonged periods without inkjet printing. This maintains optimal color rendering. The printhead sprays the preset color ink onto the transfer roller to form a transfer pattern, which is then transferred onto the substrate to create text. This avoids the uneven ink distribution and color distribution issues that can occur when the printhead directly sprays ink onto the substrate. Attached Figure Description

To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0068] Example 1

[0069] Please see Figure 1 This invention provides a solid color transfer printing method, which includes:

[0070] S1: Monitor the ink status of the first ink cartridge during the printing process and record it as the first ink status. When the first ink status reaches the first preset status, generate the preset color ink in the second ink cartridge.

[0071] Specifically, the first ink cartridge contains preset color ink, which is generated based on CMYK ink. During printing, the first ink cartridge supplies ink to the printhead, and the printhead ejects the preset color ink. During inkjet printing, the state of the first ink in the first ink cartridge is monitored. Based on the state of the first ink, it is determined whether to control the flow of CMYK ink to the second ink cartridge to generate the preset color ink. When the state of the first ink reaches a first preset state, the preset color ink is generated in the second ink cartridge. This prevents the preset color ink in the second ink cartridge from mixing and then remaining unused for a long time, which could lead to ink aging and oxidation, resulting in ink colors that do not meet printing requirements.

[0072] S2: When the first ink state reaches the second preset state, control the first ink cartridge to stop supplying ink to the printhead, and at the same time control the second ink cartridge to supply ink to the printhead.

[0073] Specifically, the timing for switching ink supply from the first ink cartridge to the printhead is determined based on the first ink state. This avoids situations where the printhead fails to stop spraying ink or ejects blank ink during printing, thus ensuring inkjet printing efficiency and quality. When the first ink state of the first ink cartridge reaches a second preset state, the first ink cartridge stops supplying ink to the printhead, while the second printhead simultaneously supplies ink to the printhead. At this time, the second ink cartridge contains the preset color ink.

[0074] S3: Monitor the ink state of the second ink cartridge during the printing process and record it as the second ink state. When the second ink state reaches the first preset state, generate the preset color ink in the first ink cartridge.

[0075] Specifically, during inkjet printing, the ink state of the second ink cartridge is detected, and based on the ink state, it is determined whether to control the flow of CMYK ink into the second ink cartridge to form the preset color ink. When the second ink state reaches a first preset state, the preset color ink is formed in the first ink cartridge, preventing the preset color ink in the first ink cartridge from mixing and then aging or oxidizing due to prolonged disuse, which could lead to ink colors that do not meet printing requirements.

[0076] S4: When the second ink state reaches the second preset state, control the second ink cartridge to stop supplying ink to the printhead, and at the same time control the first ink cartridge to supply ink to the printhead.

[0077] Specifically, the timing for switching ink supply from the second ink cartridge and the first ink cartridge to the printhead is determined based on the second ink state. This avoids situations where the printhead fails to stop spraying ink or ejects blank ink during printing, thus ensuring inkjet printing efficiency and quality are not affected. When the second ink state of the second ink cartridge reaches a second preset state, the second ink cartridge is controlled to stop supplying ink to the printhead, while the first printhead is simultaneously controlled to supply ink to the printhead. At this time, the first ink cartridge contains the preset color ink.

[0078] S5: Repeat steps S2 to S4, and control the printhead to spray the preset color ink onto the transfer roller to form a transfer image and control the transfer roller to transfer the transfer image onto the substrate until the transfer is complete.

[0079] Specifically, in existing inkjet printing applications for dyeing textiles, ink is directly printed onto the fabric through the printhead, resulting in uneven ink distribution and affecting print quality. By spraying ink onto a transfer roller to form a transfer pattern, and then using the pressure of the transfer roller to quickly and directly transfer the pattern onto the substrate, uniform ink coverage is ensured, improving print quality.

[0080] In one embodiment, such as Figure 2 As shown, the CMYK ink cartridges are connected to the first ink cartridge H1 and the second ink cartridge H2. The first ink cartridge H1 and the second ink cartridge H2 are alternately connected to the printhead 3 and supply ink to it. The printhead 3 sprays ink onto the transfer roller 4 to form a transfer image. The transfer roller transfers the transfer image onto the substrate 1 to form the printed image and text. By alternately supplying ink to the printhead with the first and second ink cartridges, the printhead is guaranteed to print continuously without ink interruption. The printhead sprays ink onto the transfer roller, and the transfer roller then transfers the transfer image onto the substrate. This avoids the direct spraying of ink from the printhead onto the substrate, which can cause problems with the poor breathability of textiles. Furthermore, the pressure of the transfer roller directly and quickly transfers the ink droplets onto the substrate, ensuring uniform ink coverage and improving print quality.

[0081] The solid color transfer printing method, apparatus, equipment, and storage medium provided in this invention alternately mixes ink in a first ink cartridge and a second ink cartridge, supplying ink to the printhead. CMYK ink is delivered to the sealed containers of the first and second ink cartridges for thorough mixing, generating a uniform preset color ink. This continuous ink supply to the printhead ensures uninterrupted ink ejection, guaranteeing printing efficiency. In a first preset state, CMYK inks are controlled to enter either the first or second ink cartridge to generate the preset color ink, ensuring uniform ink of the preset color and preventing ink oxidation or aging due to prolonged periods without inkjet printing. This ensures optimal color rendering. The printhead ejects the preset color ink onto the transfer roller to form a transfer pattern, which is then transferred onto the substrate to form text. This avoids the problem of uneven ink distribution and color uniformity that can occur when the printhead directly ejects ink onto the substrate.

[0082] In a real-world example, such as Figure 3 As shown, the solid color transfer printing method includes:

[0083] S101: Generate the preset color ink in the first ink cartridge according to the preset CMYK ink mixing ratio. For example... Figure 2As shown, the first ink cartridge H1 and printhead 3 are controlled to spray ink onto the transfer roller 4 to form a transfer image. The transfer roller 4 then transfers the transfer image onto the substrate 1 to form the detection image. When performing solid color inkjet printing, ink needs to be mixed according to a certain ratio of CMYK colors to obtain a preset color ink. Due to environmental or other reasons, color differences may occur in the ink mixed according to the ratio. To ensure that the printed color achieves the preset effect, it is necessary to check whether the mixed ink color meets the printing requirements before the actual printing. The detection image can be a custom-set image or a partial image of the image data to be printed; no limitation is made here. Based on the detection image, the ink color can be detected, and the presence of abnormalities in the printhead nozzles can also be detected.

[0084] S102: Control the printhead to spray preset color ink from the first ink cartridge onto the substrate to form a detection image.

[0085] The detection image is captured using a CCD camera 3, or scanned to obtain the detection image. The color value of the detection image is then obtained, and it is determined whether the color value is within a preset tolerance value. The preset tolerance value is a certain range above and below the color value of a preset color. When the color value of the detection image is detected to be within this range, i.e., within the preset tolerance value, the color requirements for printing are met, and the ink is adjusted according to a preset CMYK ink ratio.

[0086] S103: Obtain the ink color on the detected image and determine whether the ink color exceeds a preset tolerance value.

[0087] S104: When the ink color exceeds the preset tolerance value, adjust the CMYK ink ratio and regenerate the preset color ink.

[0088] Obtain the color value on the inspection image, adjust the CMYK ink ratio according to the color value and the preset color value, readjust the CMYK ink ratio, and use the adjusted ink to generate a new inspection image by inkjet printing. Continue to determine whether the ink color exceeds the preset tolerance value. If it does, readjust the CMYK ink ratio. If it is within the preset tolerance value, proceed to the next step.

[0089] This embodiment generates a test image by first printing with inkjet ink. It can determine whether the modulated ink is within the tolerance value of the preset color, whether the ink meets the printing requirements, and also detect whether there is any abnormality in the printhead nozzle.

[0090] In one embodiment, such as Figure 4As shown, S1: Monitoring the ink state of the first ink cartridge during the printing process, denoted as the first ink state, and when the first ink state reaches a first preset state, generating the preset color ink in the second ink cartridge includes:

[0091] S111: Obtain a first preset value based on the ink consumption rate and the modulation time of the preset color ink;

[0092] S112: Monitor the ink level in the first ink cartridge;

[0093] S113: When the ink volume reaches the first preset value, the first ink state reaches the first preset state;

[0094] S114: Generate a first ink adjustment signal, and control the four colors of ink from the CMYK ink cartridge to enter the second ink cartridge according to the first ink adjustment signal to generate the preset color ink, wherein the CMYK ink cartridge includes a C cartridge containing green ink, an M cartridge containing magenta ink, a Y cartridge containing yellow ink, and a K cartridge containing black ink.

[0095] Preferably, when the first ink state is the amount of ink in the ink cartridge, the ink consumption rate in the first ink cartridge or the second ink cartridge is obtained, the modulation time for the preset color ink in the first ink cartridge or the second ink cartridge to be modulated is obtained, and the amount of ink that the first ink cartridge and the second ink cartridge need to supply to the print head within the modulation time is obtained according to the modulation time and the ink consumption rate, and the amount of ink is the first preset value.

[0096] Preferably, a liquid level monitoring device is used to monitor the ink level in the first ink cartridge. When the liquid level monitoring device detects that the ink level in the first ink cartridge reaches the first preset value, a first ink adjustment signal is generated. Based on the first ink adjustment signal, the four colors of ink from the CMYK ink cartridge are controlled to enter the second ink cartridge to generate the preset color ink.

[0097] Preferably, a weight monitoring device can be selected to monitor the weight change of the ink in the ink cartridge, and the amount of ink in the ink cartridge can be determined based on the weight change.

[0098] When the first ink state is the amount of ink in the ink cartridge, this embodiment determines the start time for modulating the preset color ink in the second ink cartridge based on the amount of ink in the ink cartridge. This ensures that when the ink in the first ink cartridge is consumed, the second ink cartridge can be switched to supply ink to the printhead. Furthermore, the ink in the second ink cartridge will not age or oxidize due to prolonged disuse after mixing, preventing the ink color from failing to meet printing requirements. It also avoids situations where the ink in the first ink cartridge is consumed but the ink in the second ink cartridge is not fully modulated, causing the printhead to stop spraying ink or leaving blank ink, thus affecting printing efficiency and print quality.

[0099] In one embodiment, such as Figure 5 As shown, S2: When the first ink state reaches the second preset state, control the first ink cartridge to stop supplying ink to the printhead, and simultaneously control the second ink cartridge to supply ink to the printhead, including:

[0100] S211: Obtain the second preset value according to the printing preset requirements;

[0101] S212: When the ink volume of the first ink cartridge reaches the second preset value, the first ink state reaches the second preset state;

[0102] S213: Control the first ink cartridge to stop supplying ink to the printhead, and at the same time control the second ink cartridge to supply ink to the printhead.

[0103] Preferably, when the first ink state is the amount of ink in the ink cartridge, the switching timing between the first ink cartridge and the second ink cartridge is determined based on the remaining amount of ink in the first ink cartridge. When it is detected that the amount of ink in the first ink cartridge has reached the second preset value, the ink supply from the first ink cartridge to the printhead is switched to the ink supply from the second ink cartridge to the printhead.

[0104] Preferably, the second preset value is set according to printing requirements. When the first ink status is the ink volume of the ink cartridge, the second preset value can be zero or greater than zero, and the specific value is not limited here.

[0105] This embodiment switches the ink cartridge supplying ink to the printhead when the ink level reaches a second preset value, based on the ink level. The timing of switching between the first and second ink cartridges is determined according to the ink level, ensuring that the printhead does not stop spraying ink during printing and that inkjet printing efficiency and quality are not affected.

[0106] In one embodiment, such as Figure 6 As shown, S1: Monitoring the ink state of the first ink cartridge during the printing process, denoted as the first ink state, and when the first ink state reaches a first preset state, generating the preset color ink in the second ink cartridge, including:

[0107] S121: Obtain the first preset data volume based on the amount of data to be printed and the size of the ink droplets;

[0108] S122: Monitor the amount of print data generated by the printhead;

[0109] S123: When the amount of printing data from the printhead is a first preset amount of data, the first ink state reaches the first preset state;

[0110] S124: Generate a second ink adjustment signal, and control the four colors of ink in the CMYK ink cartridge to enter the second ink cartridge according to the second ink adjustment signal to generate the preset color ink, wherein the CMYK ink cartridge includes a C ink cartridge containing green ink, an M ink cartridge containing magenta ink, a Y ink cartridge containing yellow ink, and a K ink cartridge containing black ink.

[0111] Preferably, the amount of data to be printed, the size of the ink droplets ejected by the printhead, and the volume of the first / second ink cartridge are obtained. Based on the size of the ink droplets and the volume of the first / second ink cartridge, the amount of data to be printed that can be completed by the amount of ink in the cartridge is determined. This allows us to obtain the amount of data printed by the printing device when the first ink reaches a first preset state, where the printed data amount is the first preset data amount. Similarly, the amount of data printed by the printing device when the second ink reaches a first preset state can also be obtained, where the printed data amount is the first preset data amount.

[0112] Similarly, the second preset data volume corresponding to the first ink cartridge / second ink cartridge is obtained according to the above method.

[0113] Specifically, the ink status in the first ink cartridge / second ink cartridge can be obtained based on the amount of printed data. When the printing of the first preset data is detected, a second ink adjustment signal is generated to control the CMYK ink of the CMYK ink cartridge to enter the second ink cartridge and generate the preset color ink.

[0114] This embodiment determines the timing of ink mixing in the second ink cartridge based on the amount of data to be printed. This ensures that ink mixing is not done too early, which would cause the ink to age and oxidize, and that ink mixing is not done too late, which would result in the ink in the second ink cartridge not being mixed after the ink in the first ink cartridge has been used up, leading to no ink available, the printing equipment stopping printing, or affecting print quality.

[0115] In one embodiment, such as Figure 7 As shown, S2: When the first ink state reaches the second preset state, control the first ink cartridge to stop supplying ink to the printhead, and simultaneously control the second ink cartridge to supply ink to the printhead, including:

[0116] S221: Obtain the second preset data volume according to the preset printing requirements;

[0117] S222: When the amount of printing data from the printhead is the second preset amount, the first ink state reaches the second preset state;

[0118] S223: Control the first ink cartridge to stop supplying ink to the printhead, and simultaneously control the second ink cartridge to supply ink to the printhead.

[0119] Preferably, when a second preset data volume is detected, the first ink cartridge stops supplying ink to the printhead and controls the second ink cartridge to supply ink to the printhead. The ink cartridge that supplies ink to the printhead switches from the first ink cartridge supplying ink to the second ink cartridge supplying ink to the printhead, ensuring that the printhead can print ink normally.

[0120] The first preset data volume and the second preset data volume can be a part of the image data to be printed. When the first preset data volume is detected to be inkjet printed, a second ink adjustment signal is generated to control the ink to enter the second ink cartridge for ink mixing to obtain the preset color ink. When the second preset data volume is detected to be inkjet printed, the ink cartridge supplying ink to the printhead is switched to ensure that the printhead can output ink normally.

[0121] Similarly, in one embodiment, such as Figure 8 As shown, S3: Monitoring the ink state of the second ink cartridge during the printing process, denoted as the second ink state, and generating the preset color ink in the first ink cartridge when the second ink state reaches the first preset state includes:

[0122] S311: Obtain a first preset value based on the ink consumption rate and the modulation time of the preset color ink;

[0123] S312: Monitor the ink level in the second ink cartridge;

[0124] S313: When the ink volume reaches the first preset value, the second ink state reaches the first preset state;

[0125] S314: Generate a first ink adjustment signal, and control the four colors of ink in the CMYK ink cartridge to enter the first ink cartridge according to the first ink adjustment signal to generate the preset color ink, wherein the CMYK ink cartridge includes a C ink cartridge containing green ink, an M ink cartridge containing magenta ink, a Y ink cartridge containing yellow ink, and a K ink cartridge containing black ink.

[0126] When the first ink state is the amount of ink in the ink cartridge, this embodiment determines the start time of the modulation of the preset color ink in the first ink cartridge by the amount of ink in the ink cartridge. This ensures that when the ink in the second ink cartridge is consumed, the first ink cartridge can be switched to supply ink to the printhead. It also prevents the ink from aging or oxidizing due to prolonged disuse after mixing the preset color ink in the first ink cartridge, which would cause the ink color to not meet the printing requirements. Furthermore, it avoids the situation where the ink in the second ink cartridge is consumed but the ink in the first ink cartridge is not fully modulated, which would cause the printhead to stop spraying ink or produce blank ink, affecting printing efficiency and printing effect.

[0127] Similarly, in one embodiment, such as Figure 9As shown, step S4: When the second ink state reaches the second preset state, control the second ink cartridge to stop supplying ink to the printhead, and simultaneously control the first ink cartridge to supply ink to the printhead, including:

[0128] S411: Obtain the second preset value according to the printing preset requirements;

[0129] S412: When the ink volume of the second ink cartridge reaches the second preset value, the second ink state reaches the second preset state;

[0130] S413: Control the second ink cartridge to stop supplying ink to the printhead, and at the same time control the first ink cartridge to supply ink to the printhead.

[0131] Preferably, when the second ink state is the amount of ink in the ink cartridge, the switching timing between the second ink cartridge and the first ink cartridge is determined according to the remaining amount of ink in the second ink cartridge. When the amount of ink in the second ink cartridge is detected to reach the second preset value, the ink supply from the second ink cartridge to the printhead is switched to the ink supply from the first ink cartridge to the printhead.

[0132] This embodiment switches the ink cartridge supplying ink to the printhead when the ink volume reaches a second preset value, based on the ink volume. The timing of switching between the second and first ink cartridges is determined according to the ink volume, ensuring that the printhead does not stop spraying ink during printing and that inkjet printing efficiency and quality are not affected.

[0133] Similarly, in one embodiment, such as Figure 10 As shown, S3: Monitoring the ink state of the second ink cartridge during the printing process, denoted as the second ink state, and generating the preset color ink in the first ink cartridge when the second ink state reaches the first preset state includes:

[0134] S321: Obtain the first preset data volume based on the amount of data to be printed and the size of the ink droplets;

[0135] S322: Monitor the amount of print data generated by the printhead;

[0136] S323: When the amount of printing data from the printhead is a first preset amount, the second ink state reaches the first preset state;

[0137] S324: Generate a second ink adjustment signal, and control the four colors of ink from the CMYK ink cartridge to enter the first ink cartridge according to the second ink adjustment signal to generate the preset color ink, wherein the CMYK ink cartridge includes a C cartridge containing green ink, an M cartridge containing magenta ink, a Y cartridge containing yellow ink, and a K cartridge containing black ink.

[0138] This embodiment determines the ink mixing timing in the first ink cartridge based on the amount of data to be printed. This ensures that the ink will not age or oxidize due to mixing too early, nor will the ink mixing time be too late, resulting in the ink in the first ink cartridge not being mixed after the ink in the second ink cartridge has been consumed, leading to no ink available, the printing device stopping the printing operation, or affecting the print quality.

[0139] Similarly, in one embodiment, such as Figure 11 As shown, step S4: When the second ink state reaches the second preset state, control the second ink cartridge to stop supplying ink to the printhead, and simultaneously control the first ink cartridge to supply ink to the printhead, including:

[0140] S421: Obtain the second preset data volume according to the preset printing requirements;

[0141] S422: When the amount of printing data from the printhead is the second preset amount, the second ink state reaches the second preset state;

[0142] S423: Control the second ink cartridge to stop supplying ink to the printhead, and at the same time control the first ink cartridge to supply ink to the printhead.

[0143] The first preset data amount and the second preset data amount can be a part of the image data to be printed. When the first preset data amount is detected to be inkjet printed, a second ink adjustment signal is generated to control the ink to enter the first ink cartridge for ink mixing to obtain the preset color ink. When the second preset data amount is detected to be inkjet printed, the ink cartridge supplying ink to the printhead is switched to ensure that the printhead can output ink normally.

[0144] Preferably, when the first ink cartridge and the second ink cartridge have the same volume, the first preset value corresponding to the first ink cartridge and the first preset value and the second preset value corresponding to the second ink cartridge are the same, which facilitates the selection of the ink mixing timing for the first ink cartridge and the second ink cartridge, and the mixing time of each CMYK color ink in the two ink cartridges from entering the ink cartridge to completing the ink mixing is the same.

[0145] Preferably, when the volumes of the first ink cartridge and the second ink cartridge are different, the first preset value corresponding to the first ink cartridge and the first preset value and the second preset value corresponding to the second ink cartridge may be the same or different, and there is no specific limitation.

[0146] In one embodiment, the first ink cartridge and the second ink cartridge are connected by a linkage device to alternately supply ink to the printhead.

[0147] The switching between the first ink cartridge and the second ink cartridge is achieved by a linkage device, which prevents the first ink cartridge and the second ink cartridge from being connected to the printhead and the CMYK ink cartridge at the same time. Structurally, this avoids the situation where ink is mixed in the ink cartridge while ink is being supplied to the printhead, which not only improves printing efficiency but also improves the stability of ink mixing.

[0148] This embodiment determines the switching timing between the first ink cartridge and the second ink cartridge by using a second preset value, ensuring that the printhead will not stop spraying ink during the printing process, thus not affecting inkjet printing efficiency and inkjet printing quality.

[0149] In one embodiment, the first ink cartridge, the second ink cartridge, the printhead, and the CMYK ink cartridge are simultaneously connected. When ink is supplied to the first ink cartridge, the ink channel between the CMYK ink cartridge and the first ink cartridge is opened, and the channel connecting the first ink cartridge and the printhead is closed. Only ink mixing occurs on the first ink cartridge. Similarly, the second ink cartridge operates in the same way. When the first ink cartridge supplies ink to the printhead, the channel connecting the first ink cartridge and the CMYK ink cartridge is closed, and the connection channels between the second ink cartridge and the CMYK ink cartridge and the printhead are also closed. When the printing state is in a first preset state, an ink adjustment signal is generated, opening the channel between the CMYK ink cartridge and the second ink cartridge. Ink mixing occurs in the second ink cartridge. After ink mixing is completed, the connection channel between the CMYK ink cartridge and the second ink cartridge is closed. When the printing state is in a second preset state, the connection between the first ink cartridge and the printhead is closed, and the connection between the second ink cartridge and the printhead is opened, allowing the second ink cartridge to supply ink to the printhead.

[0150] This embodiment ensures that the printhead will not stop spraying ink during the printing process by opening or closing the connection between the first ink cartridge, the second ink cartridge and the CMYK ink cartridge, and the printhead. This will not affect the inkjet printing efficiency and quality.

[0151] Example 2

[0152] Please see Figure 12 When there are two or more ink cartridges supplying ink to the printhead during printing, embodiments of the present invention provide a solid color transfer printing method, the method comprising:

[0153] S01: Set the first priority for the ink cartridge to supply ink to the printhead.

[0154] The first priority is to design the ink supply sequence for multiple ink cartridges based on printing needs. When printing large-format substrates, in order to improve printing efficiency and increase inkjet printing speed, the ink in the ink cartridges is consumed quickly. To prevent the ink supply from being insufficient, two or more ink cartridges are set to supply ink to the printhead. In this case, it is necessary to set the ink supply priority of multiple ink cartridges to ensure that the ink cartridges supply ink to the printhead in an orderly manner.

[0155] S02: Set a second priority for generating preset color ink into the ink cartridge according to the first priority.

[0156] Specifically, the ink flushing sequence of the ink cartridges, which generates preset color ink, is controlled according to the ink supply sequence of the ink cartridges to ensure that the ink flushing process is carried out normally.

[0157] S03: Control the ink cartridge to supply ink to the printhead according to the first priority, monitor the ink status of the ink cartridge during the printing process, and when the ink status reaches the first preset state, control the next-level ink cartridge of the second priority to generate the preset color ink according to the second priority.

[0158] The second priority is determined based on the first priority to ensure smooth ink supply and flushing of the ink cartridges and to ensure normal inkjet printing.

[0159] S04: When the ink state reaches the second preset state, control the ink cartridge to stop supplying ink to the printhead, and at the same time control the next-level ink cartridge of the first priority to supply ink to the printhead according to the first priority.

[0160] S05: Repeat steps S03 to S04, and control the printhead to spray the preset color ink onto the transfer roller to form a transfer image and control the transfer roller to transfer the transfer image onto the substrate until the transfer is complete.

[0161] When inkjet printing requires continuous inkjet printing on large-format substrates, a large amount of ink needs to be supplied to the printhead. Multiple ink cartridges are set to supply ink to the printhead. A first priority for supplying ink to the printhead and a second priority for flushing ink to the ink cartridges are set among the ink cartridges. Based on the first priority and the second priority, ink is continuously flushed to the ink cartridges, and the ink cartridges are controlled to continuously supply ink to the printhead, so as to realize the printing of large-format substrates.

[0162] The first priority controls the order in which ink cartridges supply ink to the printhead, while the second priority controls the order in which CMYK inks flow into the cartridges to generate preset color inks. By controlling the supply of ink to the printhead from multiple cartridges and the production of ink within the cartridges according to the first and second priorities, continuous inkjet printing is ensured.

[0163] In one embodiment, step S03: controlling the ink cartridge to supply ink to the printhead according to the first priority, monitoring the ink state of the ink cartridge during the printing process, and when the ink state reaches a first preset state, controlling the next-level ink cartridge of the second priority to generate the preset color ink according to the second priority, including: obtaining the ink volume of the ink cartridge; obtaining the ink consumption rate in the ink cartridge; and determining the ink flushing time of the next-level ink cartridge in the second priority according to the ink consumption rate. Based on the ink consumption rate and the modulation time required to generate the preset color ink in the ink cartridge, the ink flushing timing of the next-level ink cartridge in the second priority is determined to ensure that the ink cartridge can supply ink to the printhead in a timely manner.

[0164] Example 3

[0165] Please see Figure 13 This invention provides a solid color transfer printing device, the device comprising:

[0166] The first printing module 1 is used to monitor the ink status of the first ink cartridge during the printing process, which is recorded as the first ink status. When the first ink status reaches the first preset status, the preset color ink is generated in the second ink cartridge.

[0167] The first switching module 2 is used to control the first ink cartridge to stop supplying ink to the printhead when the first ink state reaches the second preset state, and at the same time control the second ink cartridge to supply ink to the printhead.

[0168] The second printing module 3 is used to monitor the ink state of the second ink cartridge during the printing process and record it as the second ink state. When the second ink state reaches the first preset state, the preset color ink is generated in the first ink cartridge.

[0169] The second switching module 4 is used to control the second ink cartridge to stop supplying ink to the printhead when the second ink state reaches the second preset state, and at the same time control the first ink cartridge to supply ink to the printhead.

[0170] The loop module 5 is used to repeatedly perform the first printing module, the first switching module, the second printing module, and the second switching module, and to control the printhead to spray the preset color ink onto the transfer roller to form a transfer image and to control the transfer roller to transfer the transfer image onto the substrate until the transfer is completed.

[0171] This embodiment implements the technical solution of the solid color transfer printing method described in the above embodiment through a first printing module 1, a first switching module 2, a second printing module 3, a second switching module 4, and a circulation module 5. It alternately mixes ink in the first and second ink cartridges and supplies ink to the printhead, delivering CMYK ink to the sealed containers of the first and second ink cartridges for thorough mixing to generate a uniformly colored preset color ink. The continuous ink supply to the printhead ensures uninterrupted ink ejection, guaranteeing printing efficiency. In the first preset state, time control... CMYK inks are fed into the first or second ink cartridge to generate preset color inks, ensuring uniform ink distribution and preventing oxidation and aging of the inks due to prolonged periods without inkjet printing. This ensures optimal color rendering. The printhead sprays the preset color ink onto the transfer roller to form a transfer pattern, which is then transferred onto the substrate to create text. This process avoids the problem of uneven ink distribution and color distribution that can occur when the printhead directly sprays ink onto the substrate.

[0172] In one embodiment, such as Figure 14 As shown, the first printing module 1 includes:

[0173] The ink-generating unit 101 is used to generate the preset color ink in the first ink cartridge according to the preset CMYK ink ratio.

[0174] The inkjet printing unit 102 is used to control the printhead to spray preset color ink from the first ink cartridge onto the substrate to form a detection image.

[0175] The judgment unit 103 is used to obtain the ink color on the detection image and determine whether the ink color exceeds a preset tolerance value.

[0176] The mixing unit 104 is used to adjust the CMYK ink mixing ratio and regenerate the preset color ink when the ink color exceeds the preset tolerance value.

[0177] This embodiment generates a test image by first printing with inkjet ink. It can determine whether the modulated ink is within the tolerance value of the preset color, whether the ink meets the printing requirements, and also detect whether there is any abnormality in the printhead nozzle.

[0178] In one embodiment, such as Figure 15 As shown, the first printing module 1 includes:

[0179] First preset value acquisition unit 111: Acquires a first preset value based on the ink consumption rate and the modulation time of the preset color ink;

[0180] Ink level detection unit 112: Monitors the ink level in the first ink cartridge;

[0181] Ink state determination unit 113: When the ink volume reaches a first preset value, the first ink state reaches the first preset state;

[0182] Ink adjustment unit 114: generates a first ink adjustment signal, and controls the four colors of ink from the CMYK ink cartridge to enter the second ink cartridge according to the first ink adjustment signal to generate the preset color ink, wherein the CMYK ink cartridge includes a C cartridge containing green ink, an M cartridge containing magenta ink, a Y cartridge containing yellow ink, and a K cartridge containing black ink.

[0183] In one embodiment, such as Figure 16 As shown, the first switching module 2 includes:

[0184] Second preset value acquisition unit 211: Acquires a second preset value according to the printing preset requirements;

[0185] Ink status determination unit 212: When the ink volume of the first ink cartridge reaches the second preset value, the first ink status reaches the second preset status;

[0186] Alternating ink supply unit 213: controls the first ink cartridge to stop supplying ink to the printhead, and simultaneously controls the second ink cartridge to supply ink to the printhead.

[0187] In one embodiment, such as Figure 17 As shown, the first printing module 1 includes:

[0188] First preset data acquisition unit 121: Acquires the first preset data based on the amount of data to be printed and the size of the ink droplets;

[0189] Print data volume monitoring unit 122: Monitors the amount of print data from the printhead;

[0190] Ink status determination unit 123: When the amount of printing data from the printhead is a first preset amount of data, the first ink status reaches the first preset status;

[0191] Ink adjustment unit 124: generates a second ink adjustment signal, and controls the four colors of ink from the CMYK ink cartridge to enter the second ink cartridge according to the second ink adjustment signal to generate the preset color ink, wherein the CMYK ink cartridge includes a C cartridge containing green ink, an M cartridge containing magenta ink, a Y cartridge containing yellow ink, and a K cartridge containing black ink.

[0192] In one embodiment, such as Figure 18 As shown, the first switching module 2 includes:

[0193] Second preset data acquisition unit 221: Acquires the second preset data according to the preset printing requirements;

[0194] Ink status determination unit 222: When the amount of printing data from the printhead is the second preset amount, the first ink status reaches the second preset status;

[0195] Alternating ink supply unit 223: controls the first ink cartridge to stop supplying ink to the printhead, and simultaneously controls the second ink cartridge to supply ink to the printhead.

[0196] This embodiment alternately mixes CMYK ink in the first and second ink cartridges and supplies it to the printhead. The CMYK ink is delivered to the sealed containers of the first and second ink cartridges for thorough mixing, generating a uniform preset color ink. This continuous ink supply to the printhead ensures uninterrupted ink ejection, maintaining printing efficiency. In the first preset state, the CMYK inks are controlled to enter either the first or second ink cartridge to generate the preset color ink, ensuring uniform ink color and preventing oxidation or aging due to prolonged periods without inkjet printing. This guarantees excellent color rendering. The printhead ejects the preset color ink onto the transfer roller to form a transfer pattern, which is then transferred onto the substrate to form text. This avoids the problem of uneven ink distribution and color distribution that occurs when the printhead directly ejects ink onto the substrate.

[0197] In addition, combined Figure 1 The solid color transfer printing method described in this embodiment of the invention can be implemented by a solid color transfer printing device.

The CMYK ink is alternately mixed within the first and second ink cartridges and supplied to the printhead. This process ensures thorough mixing within the sealed containers of the first and second ink cartridges, generating a uniformly colored preset color ink. The continuous ink supply to the printhead guarantees uninterrupted ink ejection, maximizing printing efficiency. In the first preset state, the CMYK inks are controlled to enter either the first or second ink cartridge to generate the preset color ink, ensuring uniform color and preventing oxidation or aging due to prolonged periods without inkjet printing. This maintains optimal color rendering. The printhead sprays the preset color ink onto the transfer roller to form a transfer pattern, which is then transferred onto the substrate to create text.
