Description

Technical Field

[0001] The present invention relates to the field of inkjet printing technology, and in particular to a method, device, equipment and storage medium for determining ink output amount. Background Art

[0002] The inkjet printing market is stable and shows good development prospects. The inkjet printing system usually includes inkjet print heads, ink cartridges, ink pumps, ink lines, nozzles and other components. The ink cartridges are used to hold ink. Inks of different colors are usually placed in different ink cartridges. Ink cartridges are usually made of materials with good sealing properties to ensure the viscosity of the ink. The ink pump is used to transport the ink in the ink cartridge through the ink line to the nozzle of the inkjet printer. The nozzle is used to spray the ink transmitted from the ink line onto the object to be printed. Among them, there are nozzles arranged in an array on the nozzle, including multiple rows and columns.

[0003] Before printing, data processing is performed based on the image to be printed, specifically analyzing the color information of the image to be printed, calculating multiple or one ink colors corresponding to each pixel, and the ink output size corresponding to each ink color, and then obtaining the ink output color of each nozzle, the ink output size corresponding to the ink output color, and the timing sequence of ink output as a printing rule for instructing the nozzles on the nozzles to print. The nozzle is controlled to perform inkjet printing according to the printing rule, so as to realize printing the image to be printed on the object to be printed.

[0004] In the actual inkjet process, the nozzles on the nozzle may be clogged, which may be caused by ink coagulation and agglomeration caused by long-term non-operation, or the introduction of impurities. The existing technology usually deals with the problem of nozzle clogging by regularly printing test pages, cleaning the inkjet print head, etc. When the problem of nozzle clogging still cannot be solved after cleaning the inkjet print head, the nozzle will be replaced, which costs a lot. Summary of the invention

[0005] The object of the present invention is to provide a method, device, equipment and storage medium for determining ink output amount, so as to reduce printing costs.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0026] In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and effects. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and their order is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0027] It should be noted that, in the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0028] In the present invention, "at least one" means one or more, "more than one" means two or more. "And / or" describes the association relationship of the associated objects, indicating that three types of relationships may exist.

[0029] like Figure 1 As shown, an embodiment of the present invention provides a method for determining ink output amount, comprising:

[0030] Step 110, obtaining printing information of the image to be printed, position information of each nozzle on the nozzle of the inkjet printer, and preset printing conditions; the position information at least includes first position information of the blocked nozzle and second position information of the normal nozzle;

[0031] In an optional implementation, the process of determining the first position information of the blocked nozzle includes:

[0032] Along the direction of the nozzle, each row of nozzles of the nozzle is controlled to print a section of test data in turn to obtain a test pattern; when there are white stripes in the test pattern, the position information of the white stripes is determined as the first position information. It is understandable that after the above-mentioned blocked nozzles are determined, they can be set by relevant personnel to determine that the blocked nozzles set by the relevant personnel are all blocked nozzles.

[0033] In an optional embodiment, a preset image may be printed to determine the nozzle status of each nozzle on the inkjet printer nozzle, where the nozzle status includes a non-inking state and an ink-emitting state, and then the blocked nozzle is determined based on the nozzle status of each nozzle.

[0034] Specifically, the preset printing conditions may include default conditions, ambient temperature conditions, ink type conditions, and material conditions of the object to be printed, etc. Before controlling the inkjet printer to spray ink, the specific printing conditions may be determined according to the user's selection input, and then the ink output of the inkjet printer under different printing conditions may be determined.

[0035] Step 120: Based on the first position information, controlling the blocked nozzle to stop ink discharge;

[0036] Specifically, the actual ink output of the blocked nozzle is 0, that is, the blocked nozzle does not participate in printing.

[0037] In an optional embodiment, a print mask can be used to control whether each nozzle of the inkjet printer is working (jetting ink). Then, for a clogged nozzle, the clogged nozzle can be shielded by setting the print mask of each clogged nozzle of the inkjet printer to zero (or one), so that the clogged nozzle no longer works.

[0038] Step 130: Based on the first position information and the second position information, determine the normal nozzle hole adjacent to the blocked nozzle hole as the compensation nozzle hole;

[0039] After the first position information of each blocked nozzle hole and the second position information of each normal nozzle hole are known, a compensation nozzle hole is determined for the blocked nozzle hole based on the first position information of each blocked nozzle hole and the compensation nozzle hole is used to compensate the ink volume for the blocked nozzle hole.

[0040] In an optional implementation, the normal nozzle hole closest to the blocked nozzle hole is determined as the compensation nozzle hole. The closest normal nozzle hole can be the closest normal nozzle hole in front of the blocked nozzle hole, or the closest normal nozzle hole behind the blocked nozzle hole, or the closest normal nozzle hole to the left of the blocked nozzle hole, or the closest normal nozzle hole to the right of the blocked nozzle hole. Whether it is the closest in front, the closest in back, the closest on the left, or the closest on the right can be set in advance. Of course, if there is no normal nozzle hole to choose from in front, behind, left, or right, the next closest normal nozzle hole can be selected, and so on, which will not be repeated.

[0041] In another optional embodiment, the next most adjacent normal nozzle hole which is separated from the blocked nozzle hole by one nozzle hole is determined as the compensation nozzle hole.

[0042] Step 140, determining a preset initial ink output amount of each nozzle hole based on the printing information and the position information; the preset initial ink output amount includes a first initial ink output amount of the blocked nozzle hole and a second initial ink output amount of the compensated nozzle hole;

[0043] Specifically, the preset initial ink output amount may further include a third initial ink output amount of the remaining normal nozzle holes except the blocked nozzle holes and the compensating nozzle holes.

[0044] To put it another way, the preset initial ink output can be represented by the preset initial printing data. For example, in images in PRN format and PRT format, each pixel usually stores the color information and size information of the ink droplet in binary form. The embodiment of the present invention does not discuss the color problem, but only discusses the ink droplet size problem. Then, the ink output (or printing data) in the embodiment of the present invention is the ink droplet size. If the ink droplets are divided based on the size information, then in the first printing mode, the ink droplet size information is stored in the form of 2 bits on the PC side, and all ink droplets can be divided into three categories: large ink droplets, medium ink droplets and small ink droplets. If two bits are used to represent the ink droplet information, the ink droplet size can be represented by the following printing data: 00 means no ink droplets, 01 means small ink droplets, 10 means medium ink droplets, and 11 means large ink droplets. In the second printing mode, medium ink droplets and large ink droplets are not used, and only small ink droplets can complete the printing task. At this time, the ink droplets are divided into ink droplets and no ink droplets. The ink droplet size information is stored in the form of 1 bit on the PC side, so 0 represents no ink droplets and 1 represents ink droplets. It should be specially explained that the printing scenario targeted by the scheme in the embodiment of the present invention is the second printing mode. In the second printing mode, although the ink droplet size information is stored as 1 bit, since the nozzle can correspond to 2 bits of printing data information, the bit size representing the ink droplet size information can be adjusted during printing, from the original 1 bit to 2 bits. For example, 0 becomes 00, 1 becomes 01, etc.

[0045] Therefore, the ink output amount determination method may further include:

[0046] Get input information;

[0047] Based on the input information, a printing mode is determined; the printing mode includes a first printing mode and a second printing mode; in the first printing mode, ink drop information representing the amount of ink is represented by 2 bits, wherein 00 represents no ink drop, 01 represents a small ink drop, 10 represents a medium ink drop, and 11 represents a large ink drop; in the second printing mode, the ink drop information is represented by 1 bit, wherein 0 represents no ink drop, and 1 represents an ink drop, and when there is a blocked nozzle hole, the ink drop information of the compensation nozzle hole corresponding to the blocked nozzle hole is adjusted from 1 bit to 2 bits;

[0048] A printing process is performed based on the printing mode.

[0049] Step 150: Determine the actual ink output of the compensation nozzle based on the printing conditions and the preset initial ink output.

[0050] Step 150 may specifically include:

[0051] (1) Based on the default condition in the printing condition, a first ink volume compensation mode is determined; the first ink volume compensation mode is: making the ink volume level of the actual ink output volume higher than the ink volume level of the second initial ink output volume by one ink volume level;

[0052] As mentioned above, all ink droplets can be divided into three categories: large ink droplets, medium ink droplets and small ink droplets. Based on this, the ink output can be divided into, for example, four ink output levels in order from large to small. The ink output of the first ink output level is set to correspond to the first ink output, and the printing data corresponding to the first ink output is 00 (indicating that the first ink output is zero); the ink output of the second ink output level is set to correspond to the second ink output, and the printing data corresponding to the second ink output is 01; the ink output of the third ink output level is set to correspond to the third ink output, and the printing data corresponding to the third ink output is 10; the ink output of the fourth ink output level is set to correspond to the fourth ink output, and the printing data corresponding to the fourth ink output is 11.

[0053] Since the printing scenario targeted by the solution in the embodiment of the present invention is the aforementioned printing scenario where ink droplets are divided into those with ink droplets and those without ink droplets, that is, the preset initial ink output of each nozzle is either 00 or 01, and there are only two levels of ink output, but the actual ink output can be 00, 01, 10 or even 11.

[0054] (2) Based on the first ink amount compensation mode, the first initial ink output amount, and the second initial ink output amount, the actual ink output amount is determined.

[0055] Step (2) may specifically include:

[0056] Based on the first ink amount compensation mode, when the first initial ink output amount is greater than zero, if the second initial ink output amount is the preset first ink output amount, the preset second ink output amount is determined as the actual ink output amount;

[0057] If the second initial ink output is the second ink output, the preset third ink output is determined as the actual ink output; wherein the first ink output is less than the second ink output; the second ink output is less than the third ink output, and the third ink output is less than the maximum ink output.

[0058] For example, in the first ink volume compensation mode, when the first initial ink output is greater than zero, that is, the first initial ink output of the blocked nozzle is 01, if the second initial ink output of the compensating nozzle is 00 at this time, then the actual ink output of the compensating nozzle is 01; if the second initial ink output of the compensating nozzle is 01 at this time, then the actual ink output of the compensating nozzle is 10.

[0059] It is understandable that when the first initial ink output of the blocked nozzle is the first ink output (i.e., zero), the second initial ink output of the corresponding compensation nozzle does not need to be changed, and the actual ink output of the compensation nozzle is the second initial ink output of the compensation nozzle. For example, when the first initial ink output of the blocked nozzle is 00, and the second initial ink output of the compensation nozzle is 00, then the actual ink output of the compensation nozzle is 00; when the first initial ink output of the blocked nozzle is 00, and the second initial ink output of the compensation nozzle is 01, then the actual ink output of the compensation nozzle is 01.

[0060] It should be noted that the above scheme describes a specific method for determining the actual ink output of the compensation nozzle. In addition, the first actual ink output of the blocked nozzle is 0, and the second actual ink output of the remaining normal nozzles other than the blocked nozzle and the compensation nozzle is as described above: the third initial ink output of the remaining normal nozzles other than the blocked nozzle and the compensation nozzle in the preset initial ink output. In short, the final actual ink output of the remaining normal nozzles other than the blocked nozzle and the compensation nozzle is the same as the initial ink output corresponding to them and has not changed. Based on the above, after the final ink output corresponding to all nozzles, including the blocked nozzle, the compensation nozzle of the blocked nozzle, and the remaining normal nozzles other than the blocked nozzle and the compensation nozzle, is determined, printing can begin.

[0061] From the above content, it can be seen that an embodiment of the present invention provides a method for determining the ink output amount. First, the printing information of the image to be printed, the position information of each nozzle on the nozzle and the preset printing conditions are obtained; wherein the position information at least includes the first position information of the blocked nozzle and the second position information of the normal nozzle; secondly, the preset initial ink output amount of each nozzle on the nozzle of the inkjet printer is determined based on the printing information of the image to be printed; and based on the first position information and the second position information, the blocked nozzle is controlled to stop outputting ink, and the normal nozzle adjacent to the blocked nozzle is determined as the compensation nozzle; finally, based on the printing conditions and the preset initial ink output amount, the actual ink output amount of the compensation nozzle is determined. In this way, the condition that the blocked nozzle cannot output ink can be compensated by determining the actual ink amount compensation of the compensation nozzle under different printing conditions, and the blocked nozzle does not need to be replaced at a higher cost, thereby reducing the printing cost.

[0062] The above description is about the ink volume compensation method when the printing condition is the default condition. The following description is about the ink volume compensation method when the printing condition is the ambient temperature condition.

[0063] When the printing condition is the ambient temperature condition, step 150 determines the actual ink output of the compensation nozzle based on the printing condition and the preset initial ink output, specifically including:

[0064] The first step: based on the ambient temperature condition in the printing conditions, obtaining the printing ambient temperature;

[0065] Specifically, the printing environment temperature may be the temperature of the inkjet printer nozzle surroundings, or may be the indoor temperature of the studio where the inkjet printer is located.

[0066] Step 2: If the printing environment temperature is lower than the preset temperature, determine the second ink volume compensation mode; the second ink volume compensation mode is: make the ink volume level of the actual ink output volume higher than the ink volume level of the second initial ink output volume by a preset number of ink volume levels; the preset number is greater than 1;

[0067] In fact, the size of ink droplets ejected from the nozzle of an inkjet printer is related to the temperature. When the printing environment temperature is low, the ink droplet size is likely to be smaller than the printing parameters set by the manufacturer. At this time, if the first ink volume compensation mode is followed, only the ink volume level value of the actual ink output in the compensation nozzle is increased by one ink volume level, the ideal compensation effect may not be achieved. Therefore, one of the inventor's ideas is: if the printing environment temperature is lower than the preset temperature, the ink volume level of the actual ink output is made higher than the ink volume level of the second initial ink output by a preset number (for example, two) ink volume levels, so as to achieve a better compensation effect and improve printing quality.

[0068] The third step is to determine the actual ink output amount based on the second ink output compensation mode, the first initial ink output amount and the second initial ink output amount.

[0069] When the preset number is 2, the third step may specifically include:

[0070] Based on the second ink amount compensation mode, when the first initial ink output amount is greater than zero, if the second initial ink output amount is the preset first ink output amount, the preset third ink output amount is determined as the actual ink output amount;

[0071] If the second initial ink output amount is the second ink output amount, the preset fourth ink output amount is determined as the actual ink output amount, and the fourth ink output amount is the maximum ink output amount.

[0072] For example, based on the second ink volume compensation mode, when the first initial ink volume is 01, if the second initial ink volume is 00, the actual ink volume is 10;

[0073] When the first initial ink output amount is 01, if the second initial ink output amount is 01, the actual ink output amount is 11.

[0074] In an optional implementation, step 150 determines the actual ink output of the compensation nozzle based on the printing conditions and the preset initial ink output, and further includes:

[0075] If the printing environment temperature is greater than or equal to the preset temperature, determining the first ink volume compensation mode;

[0076] Based on the first ink amount compensation mode, the first initial ink output amount, and the second initial ink output amount, an actual ink output amount is determined.

[0077] The above description is about the ink volume compensation method when the printing condition is the ambient temperature condition. The following is a brief description of the ink volume compensation method when the printing condition is the ink type condition.

[0078] When the printing condition is an ink type condition, step 150 may specifically include:

[0079] Get ink type information;

[0080] When the ink type information indicates that the ink type currently used belongs to the first set type, the first ink volume compensation mode is adopted.

[0081] When the ink type information indicates that the ink type currently used belongs to the second set type, the second ink volume compensation mode is adopted.

[0082] The above description is about the ink volume compensation method when the printing condition is the ink type condition. The following is a brief description of the ink volume compensation method when the printing condition is the material condition of the object to be printed.

[0083] When the printing condition is the material condition of the object to be printed, step 150 specifically includes:

[0084] Get the material information of the object to be printed;

[0085] When the material information of the object to be printed indicates that the material of the object to be printed currently used belongs to the first type of set material, the first ink amount compensation mode is adopted.

[0086] When the material information of the object to be printed indicates that the material of the object to be printed currently used belongs to the second type of set material, the second ink amount compensation mode is adopted.

[0092] The third determination module 250 is used to determine the actual ink output amount of the compensation nozzle based on the printing conditions and the preset initial ink output amount.
