Problems solved by technology

[0004] In order to solve the technical problem that the existing color registration control technology cannot completely decouple the control of the system, the present invention provides a color registration control method and system in the process of stable speed printing of electronic axis gravure printing machines, which improves the stable speed printing in the prior art. The technical problems of slow response speed and low color registration accuracy in the process; eliminate the coupling effect of the disturbance in the previous printing unit on the error of the subsequent printing unit during stable printing, and improve the response speed and color registration accuracy of the system

Embodiment Construction

[0037] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not used to limit the protection scope of the present invention.

[0038] The control system of the gravure printing machine is composed of two parts: the tension control system and the color register control system. The purpose of tension control is to maintain the tension balance of the rewinding and unwinding part of the printing equipment, so as to avoid the occurrence of printing material wrinkles and being broken, and to lay the foundation for the color registration control of the printing unit; The color registration error caused by it can improve the color registration accuracy and product quality. From the perspective of control objectives, the two control systems are different, but in essence, the core problems they solve are both tension control problems. In ...

Abstract

The invention relates to a color register control method and system for steady printing process of electronic shaft gravure printing machines. The method comprises the steps of: feeding the printing material to a first color group through an unwinding feeding portion of an electronic shaft gravure printing machine for printing and drying; an error detecting system of the second color group judgeswhether or not the second color group and the first color group have a color registration error; if an error exists, calculating the color registration error value to obtain the angular speed change of the second color group printing plate roll, and sending a control command to a servo motor of the electronic shaft gravure printing machine; the servo motor adjusts the angular velocity of the second color group printing plate roller until the color registration error is eliminated; the error detection system of each subsequent color group determines whether there is a color registration error between the color group and the first color group, and if an error exists, eliminating the color registration error according to the color error elimination method of the second color group. The invention eliminates the coupling effect of the disturbance in the pre-printing unit on the subsequent printing unit error during the steady speed printing, and improves the response speed and the color registration accuracy of the system.

Description

technical field [0001] The invention relates to a color registration control method and system in the low-speed printing process of an electronic shaft gravure printing machine, belonging to the field of printing control. Background technique [0002] In the printing process of the electronic axis gravure printing machine, the complex pattern to be printed is decomposed into several simple patterns and engraved on the printing plate roller respectively. When printing, the printing material passes through the printing units in sequence through the feeding part, and each printing The unit prints corresponding simple patterns on the printing material, and finally obtains complex printed patterns. In the printing process, there is a problem of accurate positioning of the corresponding printing pattern between each unit, that is, the problem of color registration error. The accuracy of color registration is very important to the quality of the product. Therefore, when there is a...
