Embodiment approach

[0020] In order to enhance the color fastness of the printed matter to the greatest extent, as a preferred embodiment of the present invention: the dilution ratio Q2 of the ink prepared in step 1 is the minimum value that can meet the following two conditions: condition 1, step 2 Printed The hue of the color is the target hue; condition 2, the dot coverage P calculated by the formula falls within the preset maximum dot coverage range.

[0021] In order to ensure the effect of dot printing, as a preferred embodiment of the present invention: the maximum dot coverage ranges from 5% to 95%.

[0022] As a preferred embodiment of the present invention: the above-mentioned outlets may be frequency modulation outlets. Moreover, in order to ensure the stability of the FM dots, the size of the FM dots is between 10 μm and 30 μm. Among them, the size of the frequency modulation dots is selected as 20 μm, which can optimize the stability of the frequency modulation dots in actual produc...

Abstract

The invention discloses a printing method capable of enhancing the color lightfast capacity. The method comprises the steps that printing is conducted through ink formed by blending color ink used for color development and reducer used for diluting color of the color ink, when the dilution ratio value is Q1, hue of the ink is target hue, the dilution ratio is the weight percentage, accounted for the ink, of the reducer, and the Q1 is smaller than than 0% and larger than 100%; the printing method is characterized by comprising the steps that 1, the ink with the dilution ratio value that Q2 is smaller than the Q1 is blended; 2, printing is conducted through the ink blended in the step 1 by adopting dots, and the printing technology meets the formula of P=(100%-Q2)+10%, wherein the P represents the dot area coverage which is the percentage, accounted for the mesh area, of the dot area in a mesh in a printing technology adopting the dots, and the P is larger than 0% and smaller than 100%. Accordingly, on the basis that the color with the target hue is printed out, the color lightfast capacity of the printed color can be enhanced.

Description

technical field [0001] The invention relates to a printing method capable of enhancing color fastness to light. Background technique [0002] Due to the characteristics and blending methods of the printed matter itself, most of the colors are not light-resistant among the many color hues. These colors are prone to fading, whitening, and yellowing in sunlight, and lose their own hue. It greatly affects the appearance of the product and directly affects the sales of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a printing method capable of enhancing the color fastness to light. [0004] To solve the problems of the technologies described above, the technical scheme adopted in the present invention is as follows: [0005] A printing method capable of enhancing color fastness to light, using an ink prepared from a color ink for color development and a diluent for diluting the color of the color ink f...
