In one embodiment, when leather is used as the print medium, it comprises three steps:
step one: the processing liquid is printed in advance in the area corresponding to the image to be printed, and the processing liquid is a penetrating agent material capable of absorbing the ink of the printed image, for example: the ink for printing the image is preferably a material containing an anion, and the treatment liquid is a material containing cations, and the anions and the cations perform neutralization reaction to fix the ink for printing the image, so that the purpose of coloring the leather is achieved.
Step two: after the printing of the treatment liquid is completed, ink ejection is started according to the image data of the image to be printed, thereby forming a printed image on leather.
Step three: in order to ensure that the image is not lost or damaged in the later period, a protection treatment is needed after the image printing is finished, the protection liquid is a fixing agent containing cations, and a protection film is formed on the printed image after the cations in the fixing agent react with anions in the ink for printing the image, so that the image is prevented from fading or damaging.
It should be noted that: the method for adjusting the data of the treatment fluid and the data of the fixing agent can be adopted, so that the effect is ensured, the material can be saved, and the production cost is reduced.
It should be noted that: the invention is not limited to leather printing but may be used for textile or other printing media requiring pretreatment and/or protective treatments, and is not particularly limited herein.

s301: acquiring an ink output threshold value of each pixel point;
specifically, each ink jet mechanism (hereinafter referred to as a nozzle) is provided with ink jet holes (hereinafter referred to as nozzles) with multiple apertures, and the ink jet holes with different apertures have different ink jet amounts each time, so that the obtained pixel points have different ink dot sizes; the ink outlet quantity threshold value of the pixel point is set, so that when the ink outlet information of the pixel point is adjusted, the ink outlet quantity threshold value can be more accurate, and if the ink outlet quantity threshold value is that the ink quantity of the pixel point can be diffused to the area corresponding to 1.2 pixel points.
S302: when the ink output of the pixel points on the first diagonal line is smaller than the ink output threshold, the pixel points on the first diagonal line in the dot matrix unit are adjusted to be non-ink output pixel points, and the pixel points on the second diagonal line are adjusted to be ink output pixel points with the ink output larger than the ink output threshold;
specifically, when the ink output of the pixel points on the first diagonal is smaller than the ink output threshold, and the ink output threshold is 1.2 ink output corresponding to the pixel points, the ink output of the ink points corresponding to the nozzles with the middle aperture and the nozzles with the large aperture is larger than the ink output threshold, and the ink output of the ink points corresponding to the nozzles with the small aperture and the pixel points without the ink output are smaller than the ink output threshold; at this time, the ink outlet information of the pixel points on the first diagonal line is set as no ink outlet, that is, the pixel points on the first diagonal line are all no ink outlet pixel points (when the nozzle is used for scanning the position, the corresponding nozzle does not jet ink), the pixel points on the second diagonal line are set as ink outlet pixel points, if the pixel points on the second diagonal line are already the ink outlet pixel points before adjustment, the ink outlet amount of the pixel points after adjustment is greater than or equal to the original ink outlet amount, and if the pixel points on the second diagonal line are not the ink outlet pixel points before adjustment, the pixel points are adjusted to be the ink outlet pixel points, and the ink outlet amount can be the ink outlet amount sprayed by the small-aperture, medium-aperture or large-aperture nozzle, preferably the large-aperture nozzle; thereby ensuring that the treatment fluid in the whole lattice unit meets the requirements.
S303: when the ink output of the pixel points on the first diagonal line is larger than the ink output threshold, the corresponding pixel points on the first diagonal line in the dot matrix unit are adjusted to be the pixel points with the ink output smaller than the ink output threshold, and the pixel points on the second diagonal line are adjusted to be the ink output pixel points with the ink output larger than the ink output threshold.
Specifically, when the ink output of the pixel points on the first diagonal is greater than the ink output threshold, and the ink output threshold is 1.2 ink output corresponding to the pixel points, the ink output of the ink points corresponding to the nozzles with the middle aperture and the nozzles with the large aperture is greater than the ink output threshold, and the ink output of the ink points corresponding to the nozzles with the small aperture and the pixel points without the ink output are less than the ink output threshold; at this time, the ink output of the pixel points on the first diagonal is adjusted to be smaller than the ink output threshold, that is, the ink output pixel points corresponding to the nozzles with large aperture and medium aperture are adjusted to be the ink output pixel points corresponding to the nozzles with small aperture, or are adjusted to be the non-ink output pixel points, the pixel points on the second diagonal are set to be the ink output pixel points, and the ink output of the pixel points on the second diagonal is greater than or equal to the ink output threshold, for example: the ink outlet pixel points corresponding to the nozzles with the middle aperture or the large aperture exist on the first diagonal, and the ink outlet pixel points on the second diagonal are set as the ink outlet pixel points corresponding to the nozzles with the large aperture; if the ink outlet pixel points corresponding to the nozzles with the middle aperture or the large aperture do not exist on the first diagonal line, the ink outlet pixel points on the second diagonal line are set to be the ink outlet pixel points corresponding to the nozzles with the large aperture or the middle aperture, the ink outlet amounts of the pixel points on the first diagonal line and the second diagonal line are adjusted according to the ink outlet amounts of the ink outlet pixel points in the dot matrix unit, and therefore the problem that the treatment liquid effect is poor because the pixel points with high treatment liquid requirements are directly adjusted to be the non-ink outlet pixel points or the treatment liquid in the area beside the adjusted treatment liquid cannot be diffused to the area is avoided; meanwhile, the effect uniformity of the treatment liquid can be ensured, and the consumption of the treatment liquid can be saved.
Referring to fig. 7, there are no ink-out pixels on the first diagonal line and the second diagonal line, the pixels on the first diagonal line or the second diagonal line are adjusted to be no ink-out pixels, and the corresponding pixels on the other diagonal line are adjusted to be ink-out pixels, so that in the dot matrix unit, the interval distance between two ink-out pixels is the farthest; the interval distance between the ink-outlet pixel points and the non-ink-outlet pixel points is nearest; thereby ensuring that the processing liquid in the image area corresponding to the whole lattice unit is uniformly distributed.
It should be noted that: if the ink-non-discharge pixels exist on the two diagonals, the ink-non-discharge pixels on the diagonals with less ink-non-discharge pixels are adjusted to be ink-non-discharge pixels, and the ink-non-discharge pixels on the diagonals with more ink-non-discharge pixels are adjusted to be ink-non-discharge pixels, so that the total quantity of the ink-non-discharge pixels in the image dot matrix data is reduced, and the consumption of processing liquid is saved.
