Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0062] The invention aims at the problem in the prior art that manual operation of mechanical equipment is required to adjust the angle between nozzle plates in the calibration of four-color overprinting, which is relatively complicated and easy to damage the machine, and instead causes a decrease in precision, and provides a method for ghosting in inkjet printing The correction method and device can reduce or even eliminate the double image generated in inkjet printing.

[0063] Such as Figure 5 As shown, the embodiments of the present invention provide a method for correcting ghosting in inkjet printing, comprising the following steps:

[0064] Step 51, obtaining an electronic scanning diagram, said electronic scanning diagram is obtained based ...

Abstract

The invention provides an ink-jet printing double image correction method and apparatus, wherein the method comprises the steps of obtaining an electronic scanning pattern, the electronic scanning pattern being obtained from a detection image composed of actual pixels printed by a nozzle plate; obtaining nozzle double image parameters corresponding with the actual pixels according to the scanning pattern; and correcting the actual pixels in a pre-printed image according to the nozzle double image parameters to obtain a corrected pre-printed image. The ink-jet printing double image correction method and apparatus can mitigate and even eliminate double images generated in ink-jet printing.

Description

technical field [0001] The present invention relates to the field of correction of ghosting in inkjet printing, and in particular to a method and device for correcting ghosting in inkjet printing. Background technique [0002] In printing, four-color overprinting is usually used to print a color image. When printing, a color image needs to be decomposed into sub-images of four colors of cmyk, where c stands for cyan and m stands for magenta ), y stands for yellow (yellow), k stands for black (black). figure 1 As shown, according to the obtained sub-pictures of the four colors of cmyk, the work of the nozzle board 1 of four different colors is controlled respectively. When the carrier 2 (paper or ceramic) advances at a certain speed under the nozzle 3, the ink droplets 4 ejected by the four color nozzles 3 are superimposed in a certain order on the same position of the carrier 2 through the control of the printing system to form The desired color. Wherein, the z direction ...
