[0068] Example 1

[0069] See also Figure 1 , an embodiment of the present invention provides a pure color transfer printing method, the method comprising:

[0070] S1: monitoring the ink state of the first ink cartridge during the printing process, recorded as a first ink state, and when the first ink state reaches a first preset state, generating the preset color ink in the second ink cartridge.

[0071] Specifically, the first ink cartridge contains a preset color ink, which is generated by modulating CMYK ink. During the printing process, the first ink cartridge supplies ink to the nozzle, and the nozzle ejects the preset color ink. During inkjet printing, the state of the first ink in the first ink cartridge is monitored, and it is determined whether to control the CMYK ink to flow into the second ink cartridge according to the state of the first ink, so as to generate the preset color ink in the second ink cartridge. When the state of the first ink reaches the first preset state, the preset color ink is generated in the second ink cartridge, so as to avoid the preset color ink in the second ink cartridge from being mixed and not used for a long time, resulting in aging and oxidation of the ink, which causes the ink color to not meet the printing requirements.

[0072] S2: When the first ink state reaches a second preset state, the first ink cartridge is controlled to stop supplying ink to the nozzle, and the second ink cartridge is controlled to supply ink to the nozzle.

[0073] Specifically, the time for the first ink cartridge and the second ink cartridge to switch ink supply to the nozzle is determined according to the first ink state, so as to avoid the situation that the nozzle does not stop spraying ink or sprays blank ink during the printing process, and does not affect the inkjet printing efficiency and inkjet printing quality. When the first ink state of the first ink cartridge reaches the second preset state, the first ink cartridge is controlled to stop supplying ink to the nozzle, and the second nozzle is controlled to supply ink to the nozzle. At this time, the second ink cartridge contains the preset color ink.

[0074] S3: monitoring the ink state of the second ink cartridge during the printing process, recorded as a second ink state, and when the second ink state reaches the first preset state, generating the preset color ink in the first ink cartridge.

[0075] Specifically, during the process of the second ink cartridge supplying ink to the nozzle for inkjet printing, the ink state of the second ink cartridge is detected, and it is determined whether to control the CMYK ink to flow into the second ink cartridge according to the second ink state, so as to produce the preset color ink in the second ink cartridge. When the second ink state reaches the first preset state, the preset color ink is produced in the first ink cartridge, so as to avoid the preset color ink in the first ink cartridge from being mixed and not used for a long time, causing the ink to age and oxidize, resulting in the ink color not meeting the printing requirements.

[0076] S4: When the second ink state reaches the second preset state, the second ink cartridge is controlled to stop supplying ink to the nozzle, and the first ink cartridge is controlled to supply ink to the nozzle.

[0077] Specifically, the time for the second ink cartridge and the first ink cartridge to switch ink supply to the nozzle is determined according to the second ink state, so as to avoid the situation that the nozzle does not stop spraying ink or sprays blank ink during the printing process, and does not affect the inkjet printing efficiency and inkjet printing quality. When the second ink state of the second ink cartridge reaches the second preset state, the second ink cartridge is controlled to stop supplying ink to the nozzle, and the first nozzle is controlled to supply ink to the nozzle. At this time, the first ink cartridge contains the preset color ink.

[0078] S5: Repeat steps S2 to S4, and control the nozzle 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 to the substrate until the transfer is completed.

[0079] Specifically, when the existing inkjet printer is used for dyeing and printing textiles, the ink is directly printed onto the textiles through the nozzle, resulting in uneven ink and affecting the printing quality of the printed products. By spraying the ink onto the transfer roller to form a transfer pattern, the transfer pattern is directly and quickly transferred onto the substrate by the pressure of the transfer roller, ensuring uniform coverage of the ink on the substrate and improving the printing quality.

[0080] In one embodiment, if Figure 2 As shown, the ink cartridges of each color of CMYK are connected to the first ink cartridge H1 and the second ink cartridge H2, and the first ink cartridge H1 and the second ink cartridge H2 are alternately connected to the nozzle 3 and supply ink thereto, and the nozzle 3 sprays ink to the transfer roller 4 to form a transfer image, and the transfer roller transfers the transfer image to the substrate 1 to form a printed image and text. By alternately supplying ink to the nozzles by the first ink cartridge and the second ink cartridge, it is ensured that the nozzles will not be out of ink during printing and can continue to print, and the nozzles spray ink onto the transfer roller, and the transfer roller then transfers the transfer image on the transfer roller to the substrate, so as to avoid the nozzles spraying directly onto the substrate, which leads to poor air permeability of the textile when the substrate is a textile, and the pressure of the transfer roller is used to directly and quickly transfer the ink droplets to the substrate, so as to ensure uniform coverage of the ink on the substrate and improve the printing quality.

[0081] The pure color transfer printing method, device, equipment and storage medium provided by the embodiments of the present invention alternately mix ink in the ink cartridges and supply ink to the nozzles through the first ink cartridge and the second ink cartridge, transport CMYK ink to the first ink cartridge and the second ink cartridge sealed container for sufficient mixing, generate preset color ink with uniform color, and supply ink to the nozzles without stopping, thereby ensuring that the nozzles will spray ink without stopping and the printing efficiency is ensured; in the first preset state, the CMYK inks of various colors are controlled to enter the first ink cartridge or the second ink cartridge to generate preset color ink, thereby ensuring that uniform preset color ink is obtained and that the ink will not be oxidized or aged due to the mixed preset color ink not being inkjet printed for a long time, thereby ensuring the color development effect of the ink color, the nozzle sprays the preset color ink onto the transfer roller to form a transfer pattern, and the transfer roller then transfers the transfer pattern to the substrate to form pattern text, thereby avoiding the problem of uneven ink on the substrate and uneven color when the nozzle directly sprays ink onto the substrate.

[0082] In a real example, Figure 3 As shown, the pure color transfer printing method comprises:

[0083] S101: Generate the preset color ink in the first ink cartridge according to the preset CMYK ink ratio. Figure 2As shown, the first ink cartridge H1 and the nozzle 3 are controlled to spray ink onto the transfer roller 4 to form a transfer image, and the transfer roller 4 transfers the transfer image to the substrate 1 to form the detection image. When performing pure color inkjet printing, it is necessary to mix ink according to a certain ratio according to each CMYK color to obtain a preset color ink. Due to the environment or other reasons, the ink mixed according to the ratio may have color difference. In order to ensure that the printed color can achieve the preset effect, it is necessary to detect whether the modulated ink color meets the printing requirements before formal printing. The detection image can be a custom-set image or a partial image of the image data to be printed, which is not limited here. According to the detection image, the ink color can be detected, and whether there is an abnormality in the nozzle of the nozzle can also be detected.

[0084] S102: Control the nozzle to spray the preset color ink in the first ink cartridge to form a detection image on the substrate.

[0085] The detection image is photographed or scanned by a CCD camera 3 to obtain the detection image and the color value of the detection image, and the color value is determined to be within the preset tolerance value. The preset tolerance value is a certain range above and below the color value of the preset color. When the color value of the detection image is detected to be within the range, that is, within the preset tolerance value, the color requirement of printing is met, and ink is adjusted according to the preset CMYK ink ratio.

[0086] S103: Acquire the ink color on the detection image, and determine whether the ink color exceeds a preset tolerance value.

[0087] S104: When the ink color exceeds the preset tolerance value, the CMYK ink ratio is adjusted to regenerate the preset color ink.

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

[0089] This embodiment generates a detection image by first inkjet printing, so as to obtain whether the modulated ink is within the tolerance value of the preset color, detect whether the ink meets the printing requirements, and also detect whether there is an abnormality in the nozzle of the printhead.

[0090] In one embodiment, if Figure 4As shown, the step S1: monitoring the ink state of the first ink cartridge during the printing process, which is recorded 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: acquiring a first preset value according to the ink consumption speed and the modulation time of the preset color ink;

[0092] S112: monitoring the ink amount in the first ink cartridge;

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

[0094] S114: Generate a first ink adjustment signal, and control the four color inks of 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 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.

[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, and the modulation time for the modulation of the preset color ink in the first ink cartridge or the second ink cartridge is obtained, and the amount of ink that needs to be supplied to the nozzle by the first ink cartridge and the second ink cartridge within the modulation time is obtained based on the modulation time and the ink consumption rate, and the ink amount is the first preset value.

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

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

[0098] When the first ink state is the amount of ink in the ink cartridge, this embodiment determines the modulation start time of the preset color ink in the second ink cartridge by the amount of ink in the ink cartridge, which can ensure that when the ink in the first ink cartridge is consumed, the second ink cartridge can be switched to supply ink to the nozzle, and the preset color ink in the second ink cartridge will not be mixed and not used for a long time, causing the ink to age and oxidize, resulting in the ink color not meeting the printing requirements. It also avoids the situation where the ink in the first ink cartridge is consumed but the ink in the second ink cartridge is not modulated, causing the nozzle to stop spraying ink or blank ink, affecting the printing efficiency and printing effect.

[0099] In one embodiment, if Figure 5 As shown, the step S2: when the first ink state reaches a second preset state, controlling the first ink cartridge to stop supplying ink to the nozzle, and controlling the second ink cartridge to supply ink to the nozzle, comprises:

[0100] S211: Obtaining a second preset value according to a printing preset requirement;

[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 nozzle, and control the second ink cartridge to supply ink to the nozzle.

[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 according to the remaining amount of ink in the first ink cartridge, and when it is monitored that the amount of ink in the first ink cartridge reaches the second preset value, the ink supply from the first ink cartridge to the nozzle is switched to the second ink cartridge to supply ink to the nozzle.

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

[0105] In this embodiment, when the first ink state is the ink level in the ink cartridge, when the ink level reaches a second preset value, the ink cartridge that supplies ink to the nozzle is switched, and the switching timing between the first ink cartridge and the second ink cartridge is determined according to the ink level, thereby ensuring that the nozzle does not stop spraying ink during the printing process and does not affect the inkjet printing efficiency and inkjet printing quality.

[0106] In one embodiment, if Figure 6 As shown, the S1: monitoring the ink state of the first ink cartridge during the printing process, recorded 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, including:

[0107] S121: Obtaining a first preset data volume according to the data volume to be printed and the size of the ejected ink dots;

[0108] S122: monitoring the printing data volume of the nozzle;

[0109] S123: When the print data volume of the nozzle reaches the first preset data volume, the first ink state reaches the first preset state;

[0110] S124: Generate a second ink adjustment signal, control the four color inks of the CMYK ink cartridge to enter the second ink cartridge according to the second ink adjustment signal, and 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 volume of ink dots ejected by the ink nozzle, and the volume in the first ink / second ink cartridge are obtained, and the amount of data to be printed that can be completed by the amount of ink in the ink cartridge is determined according to the volume of the ink dots and the volume in the first ink / second ink cartridge. When the first ink state reaches the first preset state, the amount of print data printed by the printing device can be obtained, and the print data amount is the first preset data amount. Similarly, when the second ink state reaches the first preset state, the amount of print data printed by the printing device can also be obtained, and the print data amount is the first preset data amount.

[0112] Similarly, the second preset data volume corresponding to the first ink cartridge / the 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 according to the amount of print data being printed. When it is detected that the first preset data is being printed, a second ink adjustment signal is generated to control the CMYK ink of the CMYK ink cartridge to enter the second ink cartridge to generate the preset color ink.

[0114] This embodiment determines the timing of mixing the ink in the second ink cartridge by the amount of data to be printed, thereby ensuring that the ink will not age or oxidize due to premature mixing, and that the ink mixing in the second ink cartridge will not be completed after the ink in the first ink cartridge is consumed due to the ink mixing starting too late, resulting in no ink available, causing the printing device to stop printing or affecting the printing quality.

[0115] In one embodiment, if Figure 7 As shown, the step S2: when the first ink state reaches a second preset state, controlling the first ink cartridge to stop supplying ink to the nozzle, and controlling the second ink cartridge to supply ink to the nozzle, comprises:

[0116] S221: Acquire a second preset data volume according to a preset printing requirement;

[0117] S222: When the print data volume of the nozzle reaches the second preset data volume, the first ink state reaches the second preset state;

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

[0119] Preferably, when a second preset data amount is detected, the first ink cartridge stops supplying ink to the nozzle, controls the second ink cartridge to supply ink to the nozzle, and switches the ink supply from the first ink cartridge to the second ink cartridge to ensure that the nozzle sprays ink normally.

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

[0121] Similarly, in one embodiment, if Figure 8 As shown, the S3: monitoring the ink state of the second ink cartridge during the printing process, recorded 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 includes:

[0122] S311: Obtaining a first preset value according to the ink consumption speed and the modulation time of the preset color ink;

[0123] S312: monitoring the ink amount in the second ink cartridge;

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

[0125] S314: Generate a first ink adjustment signal, control the four color inks of the CMYK ink cartridge to enter the first ink cartridge according to the first ink adjustment signal, and 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 modulation start time of the preset color ink in the first ink cartridge by the amount of ink in the ink cartridge, which can ensure that when the ink in the second ink cartridge is consumed, the first ink cartridge can be switched to supply ink to the nozzle, and the preset color ink in the first ink cartridge will not be mixed and not used for a long time, causing the ink to age and oxidize, resulting in the ink color not meeting the printing requirements. It also avoids the situation where the ink in the second ink cartridge is consumed but the ink in the first ink cartridge is not modulated, causing the nozzle to stop spraying ink or blank ink, affecting the printing efficiency and printing effect.

[0127] Similarly, in one embodiment, if Fig. 9As shown, the step S4: when the second ink state reaches the second preset state, controlling the second ink cartridge to stop supplying ink to the nozzle, and controlling the first ink cartridge to supply ink to the nozzle, comprises:

[0128] S411: Obtaining a second preset value according to a printing preset requirement;

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

[0130] S413: Control the second ink cartridge to stop supplying ink to the nozzle, and control the first ink cartridge to supply ink to the nozzle.

[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, and when it is monitored that the amount of ink in the second ink cartridge reaches the second preset value, the ink supply from the second ink cartridge to the nozzle is switched to the ink supply from the first ink cartridge to the nozzle.

[0132] In this embodiment, when the second ink state is the ink level in the ink cartridge, when the ink level reaches a second preset value, the ink cartridge that supplies ink to the nozzle is switched, and the switching timing between the second ink cartridge and the first ink cartridge is determined according to the ink level, thereby ensuring that the nozzle does not stop spraying ink during the printing process and does not affect the inkjet printing efficiency and inkjet printing quality.

[0133] Similarly, in one embodiment, if Fig.10 As shown, the S3: monitoring the ink state of the second ink cartridge during the printing process, recorded 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 includes:

[0134] S321: Obtaining a first preset data volume according to the data volume to be printed and the size of the ejected ink dots;

[0135] S322: monitoring the printing data volume of the nozzle;

[0136] S323: When the print data volume of the nozzle reaches the first preset data volume, the second ink state reaches the first preset state;

[0137] S324: Generate a second ink adjustment signal, and control the four color inks of 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 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.

[0138] This embodiment determines the timing of mixing the ink in the first ink cartridge by the amount of data to be printed, to ensure that the ink will not age or oxidize due to premature mixing, or that the ink mixing in the first ink cartridge will not be completed after the ink in the second ink cartridge is consumed due to the ink mixing starting too late, resulting in no ink available, causing the printing device to stop printing or affecting the printing quality.

[0139] Similarly, in one embodiment, if Fig.11 As shown, the step S4: when the second ink state reaches the second preset state, controlling the second ink cartridge to stop supplying ink to the nozzle, and controlling the first ink cartridge to supply ink to the nozzle, comprises:

[0140] S421: Acquire a second preset data volume according to a preset printing requirement;

[0141] S422: When the print data volume of the nozzle reaches the second preset data volume, the second ink state reaches the second preset state;

[0142] S423: Control the second ink cartridge to stop supplying ink to the nozzle, and control the first ink cartridge to supply ink to the nozzle.

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

[0144] Preferably, when the volumes of the first ink cartridge and the second ink cartridge are the same, 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 management of the timing of ink mixing of the first ink cartridge and the second ink cartridge, and the modulation time from the CMYK color inks in the two ink cartridges entering the ink cartridges to the completion of 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 nozzle.

[0147] The switching between the first ink cartridge and the second ink cartridge is achieved by adopting a linkage device, so that the first ink cartridge and the second ink cartridge will not be connected to the nozzle and the CMYK ink cartridge at the same time. Structurally, it avoids the situation where ink is mixed in the ink cartridge while ink is supplied to the nozzle, which not only improves the printing efficiency but also improves the stability of ink mixing.

[0148] In this embodiment, the switching timing between the first ink cartridge and the second ink cartridge is determined by the second preset value, so as to ensure that the nozzle does not stop spraying ink during the printing process, and does not affect the inkjet printing efficiency and inkjet printing quality.

[0149] In one embodiment, the first ink cartridge and the second ink cartridge are connected to the nozzle and the CMYK ink cartridge at the same time. When supplying ink 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 nozzle is closed. Only the ink mixing action occurs on the first ink cartridge, and similarly, the second ink cartridge is the same. When the first ink cartridge supplies ink to the nozzle, the channel connecting the first ink cartridge and the CMYK ink cartridge is closed, and the channel connecting the second ink cartridge and the CMYK ink cartridge and the nozzle is closed. When the printing state is in the first preset state, an ink adjustment signal is generated, the channel between the CMYK ink cartridge and the second ink cartridge is opened, and ink mixing is performed in the second ink cartridge. After the ink mixing is completed, the channel connecting the CMYK ink cartridge and the second ink cartridge is closed. When the printing state is in the second preset state, the connection between the first ink cartridge and the nozzle is closed, and the connection between the second ink cartridge and the nozzle is opened, so that the second ink cartridge supplies ink to the nozzle.

[0150] This embodiment opens or closes the connection between the first ink cartridge, the second ink cartridge and the CMYK ink cartridge and the connection between the nozzles to ensure that the nozzles will not stop spraying ink during the printing process, and will not affect the inkjet printing efficiency and inkjet printing quality.

[0151] Example 2

[0152] See also Fig.12 When there are two or more ink cartridges supplying ink to the nozzle during printing, an embodiment of the present invention provides a pure color transfer printing method, the method comprising:

[0153] S01: Setting a first priority for the ink cartridge to supply ink to the nozzle.

[0154] The first priority is to design the ink supply sequence for multiple ink cartridges according to printing requirements. When printing large-format substrates, in order to improve printing efficiency and increase the speed of inkjet printing, the ink in the ink cartridge is consumed quickly. In order to prevent the ink supply from being delayed, more than two ink cartridges are set to supply ink to the printhead. At this time, 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: Setting a second priority of generating a preset color ink into the ink cartridge according to the first priority.

[0156] Specifically, the ink flushing sequence of the ink cartridges to generate the preset color ink in the ink cartridges is controlled according to the ink supply sequence of the ink cartridges, so as to ensure the normal progress of the ink flushing.

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

[0158] The second priority is determined according to the first priority, so as to ensure smooth ink supply and ink flushing of the ink cartridge and normal inkjet printing.

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

[0160] S05: Repeat step S03 to step S04, and control the nozzle 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 to the substrate until the transfer is completed.

[0161] When inkjet printing requires non-stop inkjet printing on large-format substrates, a large amount of ink needs to be supplied to the nozzle. Multiple ink cartridges are set to supply ink to the nozzles, and a first priority for supplying ink to the nozzles and a second priority for flushing ink to the ink cartridges are set between the ink cartridges. According to the first priority and the second priority, the ink cartridges are continuously flushed with ink and the ink cartridges are controlled to supply ink to the nozzles non-stop, thereby realizing printing of large-format substrates.

[0162] The order in which the ink cartridges supply ink to the nozzles is controlled according to the first priority, and the order in which the CMYK inks flow into the ink cartridges to generate the preset color inks is controlled according to the second priority. According to the first priority and the second priority, multiple ink cartridges are controlled to supply ink to the nozzles and produce ink in the ink cartridges to ensure the continuous inkjet printing.

[0163] In one embodiment, the S03: controlling the ink cartridge to supply ink to the nozzle according to the first priority, monitoring the ink status of the ink cartridge during printing, and when the ink status reaches the first preset status, controlling the ink cartridge of the next level of the second priority to produce the preset color ink according to the second priority, includes: obtaining the ink volume of the ink cartridge; obtaining the ink consumption speed in the ink cartridge; and confirming the ink flushing time of the next level of the ink cartridge in the second priority according to the ink consumption speed. According to the ink consumption speed and the modulation time required to produce the preset color ink in the ink cartridge, the ink flushing timing of the next level of the ink cartridge in the second priority is determined to ensure that the ink cartridge can supply ink to the nozzle in time.
