AI Technical Summary

Problems solved by technology

In this way, a lot of time is wasted in the correction process from deviation to discovery, and from discovery to correction, which requires multiple perimeters to realize the error. During this period of time, the printed products printed are all inaccurate overprints, resulting in waste products.

Embodiment Construction

[0023] The specific steps of the unit-type gravure registration printing method of the present invention are:

[0024] (1) The manuscript is processed by computer;

[0025] (2) After the text pattern printed on the printing plate roller of the first color is completed, the tracking marks that meet the requirements of the color registration system are made, and the marking group is composed of a single marking, and each marking group is based on the first printing mark. One color is the reference, the first color is arranged at a certain interval and according to the number of colors, other colors are evenly interspersed between the first colors, and the marking is made according to the number of colors, and several groups are made on the circumference of the printing plate roller. For printing, keep a certain interval between groups. The interval depends on the diameter of the plate roller, the number of printed colors and the speed of the machine. The types of printing includ...

Abstract

A chromatic printing method for a gravure printer and a flexographic pre-printer produces a tracking printing mark, which meets the need of a chromatic printing system. A printing mark group formed from single printing mark makes the first color as a base color. The first color is arranged according to a certain interval and the number of colors. The other colors intercalate evenly between the first colors. The printing mark is made according to the number of colors. A plurality of such printing marks is arranged on the version-roll circumference. The groups keep a certain interval with each other. The invention has the beneficial effects of saving rectification time, reducing the volume of waste caused by the chromatic deviation and increasing no cost.

Description

technical field [0001] The invention relates to a printing method, in particular to a color printing method of a unit-type gravure printing machine. [0002] The assortment of colorful prints is pleasing to the eye. How to improve the quality of printed matter to make it more exquisite and more realistic in color is an important issue in the printing industry. Background technique [0003] At present, the overprint printing method of the unit-type gravure printing machine is that the back color tracks the front color, that is, the second color tracks the first color, the third color tracks the second color, and so on, regardless of the size of the plate roller diameter, each Only one set of printing marks is printed on the perimeter of the plate roller, and then the color registration error is corrected to realize the color registration method of the unit-type gravure printing machine and the unit-type flexographic pre-printing machine. In this tracking method, as long as ...
