A method for automatic printing color registration by using non-automatic color registration marking plate roller

Abstract

The invention relates to the technical field of printing color registration. The purpose is to provide a method for automatic printing and color registration by using non-automatic color registration marking plate rollers. The method can use non-registering color marking plate rollers to perform automatic color registration, and has high degree of automation, accurate color registration and simple operation. The technical solution is: a method for automatic printing and color registration using non-automatic color registration marking rollers, including the following steps: 1) Engraving a short line at one end of the first color group roller as the color mark line; each color group roller Servo motors are installed Encoder; starting from the second color group version roller, each color group version roller is equipped with a photoelectric eye; 2) The printing machine is started to adjust the printing material; 3) The color mark line prints the first color on the printing material 4) Starting from the plate roller of the second color group, each color group prints its own color registration, and each encoder rotates synchronously; the operator presses the "confirm" button to confirm the standard Set value; 5) The printing material completes color printing.

Description

technical field [0001] The invention relates to the technical field of printing color registration, in particular to a method for automatic printing color registration by using non-automatic color registration marking plate rollers. Background technique [0002] Printing is a technology that transfers the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, and pressurization to copy the contents of the original manuscript in batches. It is the process of transferring the printing plate to the printing substrate (printing material) through printing machinery and special ink. In printing, there are different colors, and each color needs to be printed in stages; generally speaking, several color registrations mean the combination of several colors. Color registration is an important part of printing quality control. It is responsible for controlling the precise positioning of each design and color in the printed matt...

AI Technical Summary

Problems solved by technology

This manual color registration method is limited by the experience of the workers, the accuracy is low, and the rejection rate during the color registration process is high, which is time-consuming and laborious

However, there are still a lot of non-registered marking plate rollers still in use; since automatic color registration cannot be used, manual color registration can only be used
