Full-servo back label printing, intaglio printing, rotary screen printing and embossing register control method

Abstract

The invention discloses a full-servo back label printing, intaglio printing, rotary screen printing and embossing register control method. The method comprises the following steps of: 1, sequentially printing a dark color marks on the back surface of a paper tape material at a set interval; 2, making the paper tape material of which the back surface is printed with color marks pass through an intaglio printing unit, a rotary screen printing unit and an embossing unit, connecting a color register controller with a servo motor encoder of each unit roller respectively, and respectively recording a reference position of the servo motor encoder driven by each unit; and 3, directly adjusting the phase of the unit servo motor encoder by using the color register controller to ensure the register printing accuracy of each unit in the intaglio printing, rotary screen printing and embossing printing processes if the position of the unit servo motor encoder is different from the reference position recorded in the step 2. The full-automatic register printing method is simple in control process and can be conveniently and efficiently operated, and automatic detection and adjustment are realized completely.

Description

technical field [0001] The invention belongs to the technical field of printing machinery, and relates to the automatic control of gravure printing, rotary screen printing and embossing plate alignment synchronous registration, in particular to a full-servo back label printing and a control method for gravure printing, rotary screen, and embossing plate alignment. Background technique [0002] Because the color of the printing paste in the rotary screen wallpaper printing production line varies greatly, if the mark line is printed on the front of the paper, the sensor cannot recognize it, and the automatic overprinting function of gravure printing, rotary screen printing and embossing cannot be realized. At present, manual adjustment of overprinting technology is basically used, but the deformation of the paper when it passes through the oven of each color group is large, resulting in a large change in the tension of the paper during the subsequent printing of each unit, so t...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a full-servo back label printing and a control method for gravure printing, rotary screen, and embossing, which solves the problems of large overprint errors and unstable printing quality in the prior art using manual adjustment overprinting technology. Fully realize automatic overprinting of rotary screen printing, gravure printing and synchronous embossing printing
