Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a jet orifice compensation printing method and related equipment, which are used for improving the ink jet printing efficiency and reducing the ink jet printing cost.
Referring to fig. 1, a first aspect of the present application provides a nozzle compensation printing method, including the following steps 101 to 105:
101. determining and shielding each clogged orifice of the inkjet printing device;
when printing an image using an inkjet printing apparatus in which there are clogged ejection holes, it is first necessary to determine each clogged ejection hole of the inkjet printing apparatus and shield all the clogged ejection holes of the inkjet printing apparatus.
In some embodiments, this step may be implemented by: printing a preset image to determine a nozzle hole state of each nozzle hole in the inkjet printing device; each clogged orifice of the inkjet printing apparatus is determined according to an orifice state of each orifice. Specifically, an image may be preset for determining the nozzle hole state, and then the clogged nozzle hole may be determined according to the nozzle hole state of the nozzle hole, where the preset image may be any image that tests the nozzle hole state (whether clogged) of each nozzle hole in the inkjet printing apparatus. It can be known that the blocked orifices of the inkjet printing apparatus can also be set by an operator using the inkjet printing apparatus, and the blocked orifices set by the operator are determined to be all the blocked orifices of the inkjet printing apparatus.
102. And respectively determining the compensation jet holes of each blocked jet hole when the target image is printed by using different snapshot algorithms.
After each blocked nozzle of the inkjet printing device is determined, the compensation nozzle corresponding to each blocked nozzle needs to be calculated when the inkjet printing device prints a target image by using different snapshot algorithms. Wherein, different snapshot algorithms include but are not limited to: a no-snapshot algorithm, a secondary snapshot algorithm, a tertiary snapshot algorithm, and a quartic snapshot algorithm. The non-snapshot algorithm means that the target image is printed once in the process of printing the target image; the snapshot algorithm means that the target image can be printed for a plurality of times in the process of printing the target image, and different snapshot algorithms are named according to the printing times required by printing completion. If the printing is finished and needs to be performed twice, performing a secondary snapshot algorithm; three times of printing is needed after the printing is finished, and a three-time snapshot algorithm is adopted; four prints are required for printing completion, and the four-time snapshot algorithm is adopted. The second snapshot algorithm, the third snapshot algorithm and the fourth snapshot algorithm are all snapshot algorithms.
According to the above, when different snapshot algorithms are used to print a target image, the compensation nozzle holes corresponding to the same blocked nozzle hole may be different.
103. And respectively determining the compensation printing data of each jet hole in the ink-jet printing device when the target image is printed by using different snapshot algorithms according to the compensation jet hole of each blocked jet hole when the different snapshot algorithms are used.
104. And determining a target snapshot algorithm from the different snapshot algorithms according to the compensation printing data of each jet orifice when the different snapshot algorithms are used.
After the compensated print data corresponding to each nozzle hole is determined in step 103 when different snapshot algorithms are used, the snapshot algorithm with a better print effect is determined as the target snapshot algorithm from the plurality of snapshot algorithms. Specifically, the offset print data corresponding to each nozzle hole when different snapshot algorithms are used may be determined by an operator of the inkjet printing apparatus or the inkjet printing apparatus.
105. And printing the target image according to the compensation printing data corresponding to the target snapshot algorithm.
After the target snapshot algorithm is determined in step 104, the target image is determined to be printed according to the compensation print data corresponding to the target snapshot algorithm determined in step 104.
In the embodiment of the application, the blocked jet holes can be predetermined and shielded, and then the corresponding compensation jet hole is determined for each blocked jet hole. Then, based on the compensated orifice corresponding to each clogged orifice, compensated print data corresponding to each orifice in the inkjet printing apparatus when printing the target image using different printing algorithms is determined. And finally, printing the target image according to the compensation printing data corresponding to the target printing algorithm. Under the condition that the spray hole is blocked and the spray head is not replaced, the image printing effect of the ink-jet printing device can be ensured, the ink-jet printing efficiency is improved, and the ink-jet printing cost is reduced. In addition, compensation printing data of each jet hole in the ink-jet printing device are calculated, then a target image is printed based on the compensation printing data of each jet hole corresponding to the target snapshot algorithm, and jet hole compensation in the printing process is directly achieved through the compensation printing data.
In some embodiments, the foregoing step 102 may be specifically implemented by: and if the snapshot algorithm is a non-snapshot algorithm, determining that the spray hole which is not the blocked spray hole in the adjacent spray holes corresponding to each blocked spray hole is the compensation spray hole corresponding to each blocked spray hole. If the snapshot algorithm is a snapshot algorithm, judging whether spray holes which are not blocked spray holes exist in the snapshot spray holes corresponding to each blocked spray hole; if the nozzle holes which are not blocked exist in the snapshot nozzle hole corresponding to each blocked nozzle hole, determining that any nozzle hole which is not blocked in the snapshot nozzle hole corresponding to each blocked nozzle hole is a compensation nozzle hole of each blocked nozzle hole; and if the snapshot spray holes corresponding to each blocked spray hole are blocked spray holes, determining that the spray hole which is not the blocked spray hole in the adjacent spray holes corresponding to each blocked spray hole is the compensation spray hole corresponding to each blocked spray hole.
Specifically, if the snapshot algorithm is a non-snapshot algorithm, determining that a nozzle hole which is not a blocked nozzle hole in adjacent nozzle holes of the blocked nozzle hole is a compensation nozzle hole corresponding to the blocked nozzle hole. In practical application, if the blocked spray hole only has one adjacent spray hole, if the adjacent spray hole is not the blocked spray hole, the adjacent spray hole is determined as the compensation spray hole corresponding to the blocked spray hole; if two adjacent spray holes exist in the blocked spray hole, if only one adjacent spray hole in the two adjacent spray holes is not the blocked spray hole, the adjacent spray hole which is not the blocked spray hole is determined to be the compensation spray hole of the blocked spray hole.
If the snapshot algorithm is a snapshot algorithm, determining whether a snapshot nozzle hole corresponding to the blocked nozzle hole exists a nozzle hole which is not the blocked nozzle hole, and if the snapshot nozzle hole corresponding to the blocked nozzle hole exists a nozzle hole which is not the blocked nozzle hole, determining that any snapshot nozzle hole which is not the blocked nozzle hole and corresponds to the blocked nozzle hole is a compensation nozzle hole corresponding to the blocked nozzle hole. And if the snapshot spray holes corresponding to the blocked spray holes are all blocked spray holes, determining all spray holes which are not blocked spray holes in the adjacent spray holes corresponding to the blocked spray holes as compensation spray holes corresponding to each blocked spray hole. The snapshot nozzle hole is another printing nozzle hole of a different number of printing times corresponding to the printing position corresponding to the number of printing times of the blocked nozzle hole, and the other printing nozzle holes are other nozzle holes except the blocked nozzle hole in the plurality of nozzle holes of the different number of printing times corresponding to the printing position.
It can be known that if the compensation jet orifice is a snapshot jet orifice, the lossless compensation of blocking the jet orifice can be realized; if the compensation jet holes are adjacent jet holes, the lossy compensation of blocking the jet holes can be realized.
In this embodiment, a specific determination mode for compensating the nozzle holes is provided, so that lossy compensation can be implemented for a non-snapshot algorithm, and lossless compensation or lossy compensation can be implemented for a snapshot algorithm.
It is appreciated that, after the compensated orifice determination, the orifices in an inkjet printing device can be classified into three categories: blocking spray holes, compensating spray holes and residual spray holes. Wherein the remaining orifices are all of the orifices in the inkjet printing device except for the plugged orifices and the compensated orifices.
In some embodiments, the determination of the compensated print data for each orifice in the inkjet printing device (i.e., the aforementioned step 104) may be accomplished by: determining that the compensation printing data of each blocked jet orifice in the ink-jet printing device is zero when the target image is printed by using different snapshot algorithms; determining the compensation printing data of each compensation jet hole in the ink-jet printing device when the target image is printed by using different snapshot algorithms according to the initial printing data of each compensation jet hole and the initial printing data of the blocked jet hole corresponding to each compensation jet hole; and determining the compensation printing data of each residual jet hole in the ink-jet printing device when the target image is printed by using different snapshot algorithms as the initial printing data of each residual jet hole, wherein the residual jet holes are jet holes except each blocked jet hole and each compensation jet hole in the ink-jet printing device. The compensated print data refers to compensated print data of each nozzle hole, which is determined based on initial print data of each nozzle hole after considering the nozzle hole blockage and can still achieve a good image printing effect under the condition that the nozzle hole blockage exists, where the initial print data of each nozzle hole refers to initial print data required to be printed by each nozzle hole when a target image is printed under the condition that each nozzle hole of the inkjet printing device can be normally used (i.e. not blocked).
Specifically, if the compensation printing data for blocking the nozzle hole is zero, the blocked nozzle hole does not participate in printing. The remaining nozzle holes are not blocked and do not participate in compensation, and the initial printing data corresponding to each remaining nozzle hole can be directly determined as the compensation printing data of the remaining nozzle hole. Determining printing data of compensation spray holes, namely determining that each blocked spray hole compensated by the compensation spray hole has a plurality of compensation spray holes respectively, and if each blocked spray hole compensated by the compensation spray hole has only one compensation spray hole (the compensation spray hole), determining the compensation printing data of the compensation spray hole as initial printing data of the compensation spray hole and all initial printing data of each compensated blocked spray hole; if each blocked jet orifice compensated by the compensation jet orifice has two compensation jet orifices (one is the compensation jet orifice), the compensation printing data of the compensation jet orifice is determined as the initial printing data of the compensation jet orifice and the partial (such as half) initial printing data of each blocked jet orifice. For example, if the compensation nozzle hole a needs to compensate for the blocked nozzle hole B, the blocked nozzle hole C, and the blocked nozzle hole D, two compensation nozzle holes corresponding to the blocked nozzle hole B, only one compensation nozzle hole corresponding to the blocked nozzle hole C, and two compensation nozzle holes corresponding to the blocked nozzle hole D; the compensation printing data of the compensation nozzle hole a is all the initial printing data corresponding to the compensation nozzle hole a, half the initial printing data corresponding to the blocked nozzle hole B, all the initial printing data corresponding to the blocked nozzle hole C, and half the initial printing data corresponding to the blocked nozzle hole D.
Further, in some specific implementations, if the print mask is used to control whether each nozzle hole in the inkjet printing apparatus is operated (whether to eject ink), the blocked nozzle hole may be masked in the foregoing step 101 by setting the print mask of each blocked nozzle hole in the inkjet printing apparatus to zero (or one), so that the blocked nozzle hole does not operate any more. The printing mask is not limited specifically, as long as the printing mask only corresponds to two numerical values, one numerical value identifies that the nozzle hole works normally, and the other numerical value identifies that the nozzle hole is shielded (i.e., does not work). On this basis, when the compensation printing data of different nozzles are determined in the foregoing step, the compensation printing data of the clogged nozzles and the compensation printing data of the remaining nozzles may be respectively determined as corresponding initial printing data, and the determination method of the compensation printing data of the compensation nozzles is similar to that in the foregoing embodiment, and is not repeated here. And finally, determining actual printing data according to the printing mask of each spray hole and the corresponding compensation printing data, and printing the target image according to the actual printing data of each spray hole.
In this embodiment, because the print mask for blocking the nozzle holes is set to zero, and the print masks for the remaining nozzle holes and the compensation nozzle holes are 1, the actual print data determined according to the print mask and the compensation print data is zero, that is, no printing is performed, and the actual print data according to the remaining nozzle holes and the compensation nozzle holes is the corresponding compensation print data.
Specifically, in some embodiments, the final print data validation process for each nozzle hole of the non-snapshot algorithm may refer to fig. 2, the final print data validation process for each nozzle hole of the secondary snapshot algorithm may refer to fig. 3, the final print data validation process for each nozzle hole of the tertiary snapshot algorithm may refer to fig. 4, and the final print data validation process for each nozzle hole of the quaternary snapshot algorithm may refer to fig. 5. The final print data, that is, the print data used for printing the target image, may be the compensation print data or the actual print data in the foregoing embodiment; the current hole is any jet hole for which final printing data is not determined.
