Problems solved by technology

[0005] The traditional printing color separation is C, M, Y, K. If the traditional color separation method is used in the flexo printing process, the face is prone to dirty plates when printing the faces of the characters, and frequent plate changes will cause the printing effect to fail to meet the requirements. also increased printing costs

Embodiment Construction

[0012] The following examples can enable those skilled in the art to understand the present application more comprehensively, but do not limit the present application in any way.

[0013] Blue ink C, red ink M, yellow ink Y, and black ink K are used as four-color inks for printing; the Lab values ​​of the four-color inks are respectively: blue ink C (L=50.50±2, a=1.50±1, b=-2.0±1), red ink M (L=70.40±2, a=2.5±1, b=3.0±1), yellow ink Y (L=74.0±2, a=0.95±1, b=5.0 ±1), black ink K (L=11.98±2, a=0.35±1, b=0.30±1).

[0014] The present invention defines the optimized color separation as: M, Y, K. Use K and M to fill in the C color hue, so that the printed face of the character is not easy to get dirty, the face is rosy and soft, and the whole face will be brighter than that with C.

[0015] The present invention can avoid the problems of traditional printing such as fading and smearing of characters’ facial images when the water-based ink dries, and solves the problem of black an...

Abstract

The invention provides a flexible printing figure face color optimization control method. The method comprises the following steps of using red M, yellow Y and black K to replace four-color printing, and using black K and red M to supplement a C color hue; the face of a person printed through the method is not prone to being stained, the face is ruddy and soft, and the whole face is brighter than the face with C; in addition, the problems that in traditional printing, when water-based ink is dried, printing dry fading and over-bottom smearing are generated, and consequently a figure face image is dirty can be solved, and the problems that in traditional printing, black and white printed matter is impure in color, and the printed matter is dark and dim after being dried are solved; and black-gray image printing of warm hues or cold hues or other hues can be achieved, meanwhile, fine-level reduction can be supplemented, and the requirement for the printing effect is met.

Description

technical field [0001] The present application relates to the field of printing, and in particular, relates to a method for optimizing and controlling the face color of a character in flexographic printing. Background technique [0002] Four-color printing generally refers to the printing process of using yellow, red, cyan (blue) primary color inks and black inks to reproduce various colors of color originals. Among them, C: the abbreviation of Cyan in Chinese: blue; M: the abbreviation of Magenta in Chinese: magenta; Y: the abbreviation of Yellow in Chinese: yellow; K: the abbreviation of Black, Chinese: black. [0003] Due to the requirements of the printing process or the consideration of economic benefits, when using the four-color printing process, in order to ensure the correct restoration of the tone and color, the thickness of the ink layer of each color is strictly controlled. Usually in four-color printing, the density of black solids does not exceed 1.8. Printing...
