Referring to fig. 2, an embodiment of the present invention provides a method for processing feathering of print data, in which a first mask template and data in a first print data matrix, which start to have a height equal to a feathering length in a sub-scanning direction, are subjected to an and operation, and a second mask template and data in a first print data matrix, which start to have a height equal to the feathering length in a direction opposite to the sub-scanning direction, are subjected to an and operation, so that errors caused by printing accuracy and a driving motor are diffused as data of the first print data matrix are dispersed, and thus, overlapping or blank spaces existing in a print image disappear, thereby ensuring that the print image is not distorted seriously and improving the quality and quality of the print image. The method comprises the following steps:
s1, acquiring a printing data matrix corresponding to the feathering length and the nozzle scanning once along the main scanning direction and recording the printing data matrix as a first printing data matrix;
referring to fig. 3, the head 100 has a plurality of nozzles 101, the plurality of nozzles 101 are distributed at uniform intervals along a sub-scanning direction L2, and the head 100 scans back and forth along a main scanning direction L1 to form an image; in this embodiment, the height of the print data matrix corresponding to one scan of the head 100 in the main scanning direction L1 is equal to the number of nozzles 101 on the head 100, a direction L2 perpendicular to the main scanning direction is a sub-scanning direction of the head 100, and if the number of nozzles 101 on the head 100 is m and m is an integer greater than or equal to 1, the first print data matrix is:
wherein n is the width of the first printing data matrix, n is an integer greater than or equal to 1, and the width of the first printing data matrix is determined by the printing width and the printing precision.
S2, acquiring a first mask template and a second mask template;
preferably, the height of the first mask stencil is equal to the feathering length, and the second mask stencil is equal to the first mask stencil subtracted from the full one matrix, the first mask stencil being the first mask matrix, and the second mask stencil being the second mask matrix. In this embodiment, the width of the first mask matrix is equal to the width of the first print data matrix, and the width of the second mask matrix is equal to the width of the first print data matrix.
The mask template is determined according to different printing requirements and different printing scenes, as shown in fig. 4, the density of the mask template gradually and uniformly transits from 0 to 100% from top to bottom, the position with the density of 0 corresponds to the edge part of a printer nozzle, the position with the density of 100% corresponds to the data which is not subjected to mask processing, and the mask template is suitable for most scenes. As shown in fig. 5, the mask stencil has a laterally non-uniform concentration gradient, and a laterally cyclically varying concentration band, which helps to eliminate the yin-yang channels generated when the printer performs printing back and forth, wherein the yin-yang channels are the ink drop points of the printer caused by the influence of gravity and inertia during the movement process, so that the dots printed by the nozzle during the printing back and forth process are distributed irregularly, and the printed image has a non-uniform ink concentration. As shown in fig. 6, the mask stencil has non-uniform density distribution in both the longitudinal and transverse directions and a filament portion in the middle, and not only can eliminate the yin and yang channels, but also can eliminate transverse joint marks generated by the nozzle printing back and forth. As shown in fig. 7, the mask template is obtained by performing phase-joining of upper and lower data layers, and not only can eliminate yin and yang channels, but also can eliminate the phenomenon of longitudinal excessive non-uniformity. Referring to fig. 8, the mask template is a combination of the two templates of fig. 5 and 6, which can further eliminate some defects that may be generated by one template. The mask template can solve the problem of poor printing effect caused by unheated or poor ink absorption capacity of a printing carrier, as shown in FIG. 9.
In this embodiment, the mask matrix is obtained by processing the corresponding gray-scale image through an error diffusion algorithm in a halftone algorithm, which is a common technique in the printing field and is not described herein again.
S3, according to the feathering length, performing an and operation on data having a starting height in the sub-scanning direction equal to the feathering length in the first mask template and the first print data matrix, performing an and operation on data having a starting height in the direction opposite to the sub-scanning direction equal to the feathering length in the second mask template and the first print data matrix, and recording the first print data matrix subjected to the two and operations as a second print data matrix.
Preferably, the feathering length is greater than half the height of the first printed data matrix. Referring to fig. 10, when the feathering length is greater than half of the height of the first print data matrix, the data in the first print data matrix will be feathered and some overlapping feathering will occur, in which case the process of printing the data is as follows: if the nozzle 100 has 5 nozzles 101, the width of the nozzle 100 scanned once along the main scanning direction is 5 dots, and the length of the feathering is 3 dots, then the first print data matrix B corresponding to the image I scanned once along the main scanning direction by the nozzle 100 is:
intercepting data with the height equal to the feathering length from the first printed data matrix along the sub-scanning direction as a fourth processed data matrix, as shown in FIG. 10, wherein the image corresponding to the fourth processed data matrix is I1Said fourth processed data matrix B1Comprises the following steps:
intercepting data with the same height as the feathering length from the first print data matrix in the direction opposite to the sub-scanning direction as a fifth processed data matrix, as shown in FIG. 10, wherein the image corresponding to the fifth processed data matrix is I2Said fifth processed data matrix B2Comprises the following steps:
setting the first mask template C1Comprises the following steps:
the second mask stencil C2Comprises the following steps:
in this embodiment, the specific process of performing an and operation on the data having a height equal to the feathering length in the sub-scanning direction in the first mask template and the first print data matrix is as follows:
in this embodiment, the specific process of performing an and operation on the data having a starting height equal to the feathering length in the direction opposite to the sub-scanning direction in the second mask template and the first print data matrix is as follows:
processing data matrix B from the fourth1And said fifth processed data matrix B2It can be clearly seen that the two data matrices are partially overlapped, and the data of the overlapped part is processed twice when performing the and operation with the mask template, so that the ink output data in the overlapped data matrix is reduced, which may cause local unevenness of the printed image, and in order to solve the possible unevenness, the following steps may be further adopted with reference to fig. 11:
s4, obtaining the original data matrix of the data matrix which is subjected to the two-time AND operation in the second printing data matrix from the first printing data matrix, wherein the original data matrix D1Comprises the following steps:
D1＝[b31 b32 b33 b34 b35]
s5, acquiring a third mask template with the height equal to that of the original data matrix, and performing an AND operation on the third mask template and the original data matrix to obtain a fourth mask template;
s6, performing an or operation on the fourth mask template and the data obtained by performing the two-time and operation on the second print data matrix, and recording the second print data matrix subjected to the or operation as a fourth print data matrix.
In this embodiment, the third mask template and the original data matrix are subjected to an and operation to filter data corresponding to non-ink-output point data in the original data matrix in the third mask template, and then the fourth mask template and the data subjected to the two and operations in the second print data matrix are subjected to an or operation, and the second print data matrix subjected to the or operation and the fourth print data matrix mentioned in the present invention are used for printing during actual printing, so that ink output data in the eclosion overlapping area in fig. 11 is increased, and the problem that the ink output data in the eclosion overlapping area is reduced due to the two and operations, so that the printed image is locally uneven is solved.
Preferably, the feathering length is equal to or less than half the height of the first printed data matrix.
Referring to fig. 12, when the feathering length is less than or equal to half of the height of the first print data matrix, the step S3 specifically includes:
s311, dividing the first printing data matrix into three parts in sequence along a sub-scanning direction according to the feathering length, wherein the three parts are respectively a first processed data matrix, a second processed data matrix and a third processed data matrix, the heights of the first processed data matrix and the third processed data matrix are equal to the feathering length, and the sum of the heights of the first processed data matrix, the second processed data matrix and the third processed data matrix is equal to the height of the first printing data matrix;
specifically, referring to fig. 13, if there are 6 nozzles 101 on the inkjet head 100, the width of the inkjet head 100 scanned 1 time along the main scanning direction is 6 dots, and the feathering length is 2 dots, then the image T scanned 1 time along the main scanning direction by the inkjet head 100 corresponds to the first print data matrix, the image T is divided into three parts, i.e., T1, T2, and T3 according to the feathering height, the image T1 corresponds to the first processed data matrix, the image T2 corresponds to the second processed data matrix, and the image T3 corresponds to the third processed data matrix, and the specific allocation rule of the first print data matrix is as follows:
where E denotes a first print data matrix, E1 denotes a first processed data matrix, E2 denotes a second processed data matrix, and E3 denotes a third processed data matrix.
S312, performing an AND operation on the first mask template and the first processed data matrix to obtain a first printing sub-data matrix, and performing an AND operation on the second mask template and the third processed data matrix to obtain a second printing sub-data matrix; in this embodiment, the second processed data matrix is not processed.
S313, combining the first printing sub data matrix, the second processing data matrix and the second printing sub data matrix in sequence to form a second printing data matrix.
Referring to fig. 14, the first print data matrix includes an image data matrix and a padding data matrix, and the image data matrix is obtained by performing halftone algorithm processing on the image to be printed, and all elements in the padding data matrix are zero. For example, when the inkjet head 100 enters or leaves the printing area 201 on the printing medium 200, when the inkjet head 100 scans in the main scanning direction for 1 time, a part of the nozzles 101 that are not in the printing area 201 do not have a corresponding image data matrix, at this time, the part of the nozzles 101 that are not in the printing area need to be correspondingly filled with data 0, that is, a data matrix is filled, so that the entire inkjet head 100 corresponds to data, where the data 0 indicates that no ink is present in this embodiment; when the head 100 completely enters the printing area 201, and all the nozzles 101 are in the printing area 201 when the head scans 1 time along the main scanning direction, the first printing data matrix corresponding to the head 100 is the image data matrix.
Referring to fig. 15 and fig. 19 to fig. 21, the present invention further discloses an inkjet printing method, wherein for a certain region F to be printed, the J1 nozzle and the J2 nozzle on the nozzle 100 form an image 19 by discharging ink from the region F to be printed in the nth scan according to the printing data; when the printing medium moves a distance G along the sub-scanning direction L2 in the (n + 1) th scanning, the area F to be printed is inked by the J3 nozzle and the J4 nozzle on the spray head 100 according to the printing data to form an image 20; when the printing medium moves a distance G along the sub-scanning direction L2 during the n +2 th scanning, the area F to be printed is inked by the J5 nozzle and the J6 nozzle on the spray head 100 according to the printing data to form the image 20; when the printing medium moves a distance G along the sub-scanning direction L2 during the (n + 3) th scan, the image 21 is formed in the area F to be printed by the ink ejected from the nozzles J7 and J8 of the head 100 according to the printing data, and the images formed by the four scans are combined in the order of the specific dots to form the image of the area F to be printed. It can be seen from the figure that the image 19 formed by the nth scan of the J1 nozzle and the J2 nozzle covers the image 21 formed by the n +3 th scan of the J7 nozzle and the J8 nozzle, so as to present the image 20, while the print data matrix corresponding to the J1 nozzle and the J2 nozzle is the data matrix processed by the first mask template in the first print data matrix corresponding to the spray head 100 in the above-mentioned print data feathering method which scans 1 time (in this embodiment, the nth scan) along the main scanning direction L1, and the print data matrix corresponding to the J7 nozzle and the J8 nozzle is the data matrix processed by the second mask template in the first print data matrix corresponding to the spray head 100 in the above-mentioned print data feathering method which scans 1 time (in this embodiment, the n +3 th scan) along the main scanning direction L1, since the second mask template is the full matrix minus the first mask template, i.e.e. the first mask template is complementary to the second mask template, therefore, the data matrix obtained after the phase operation of the first mask template and the original printing data phase and the data matrix obtained after the phase operation of the second mask template and the original printing data phase are complementary, namely the first mask template enables the original printing data matrix to be thinned out so that the error of uneven density of a printed image caused by motor or stepping error is diffused, and then the second mask template is used for completely supplementing the original printing data so that the image density is even. Although the nth printing data of the area F to be printed is compensated for the (n + 3) th time, and the processing of the printing data in the printing data feathering method is performed on the printing data corresponding to a certain scanning of the nozzle 100, according to the inkjet printing method, the same processing is performed on the printing data corresponding to each scanning of the nozzle 100, and the feathering of the printing data in a certain area is not the same, so that the density of the whole image is uniform, and the quality of the product is ensured.
FIG. 16 is a diagram showing the effect of inkjet printing on the print data processed by the method for feathering the print data according to the present invention, compared with FIG. 1, the density of the diagram is uniform and no obvious pass is found, so that the quality of the printed product can be ensured by processing the print data by the method for feathering the print data according to the present invention.
