A digital printing method for solving digital printing metamerism

Abstract

The invention embodiment provides a digital printing method for solving the same-color abnormal-spectrum phenomenon of digital printing, and belongs to the technical field of printing. According to the method, the color purity of ink or printing ink is improved, a professional image-text dot matrix system is used for carrying out specialized lattice processing on the graph to be printed, so that the distribution and the arrangement of the color dots of the pattern are uniformly dispersed, and a light reflection value is consistent when the color is viewed from all directions; the color of theprinted matter in various illumination environments is consistent; meanwhile, the software can judge the color characteristic according to the pattern, so that the color output sorting during digitalprinting is reasonably arranged, and the light reflection is consistent to obtain a stable color reflection value; after the printing ink and the ink saturation are increased, the single-point data volume is improved through software control, the amount of ink on the single point can be increased, and the adjustment of the amount of ink can be controlled; and the specific single-point ink amount is determined according to the specific single-color saturation degree of the ink or the printing ink so as to achieve consistent color output performance of the digital presswork under different lightconditions.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a digital printing method for solving the phenomenon of metamerism in digital printing. Background technique [0002] Digital printing often has the problem of metamerism that cannot be solved. The most prominent problem is light box painting, packaging printing, etc. Due to the color purity of ink and ink in traditional printing and digital printing processes, it is inevitable that it cannot reach 100% pure color. Requirements, it is inevitable that other colors will be mixed in a single color, which will cause interference in hue. The most intuitive performance is that the higher the monochromatic color purity is, the higher the gray value of the color will be. When the gray value reaches a certain level, the printed pattern will become black, and the printed matter will appear in different colors. Under lighting conditions, different color shades and hues appear. A more obv...

Problems solved by technology

However, the traditional solution has many inconveniences in actual implementation. For example, the display of the picture will be abnormal if the lighting environment changes slightly. In order to restore the color accurately, it may be necessary to continuously do curve calibration, so that the consistency of the picture quality and production efficiency will be greatly reduced
