Method, system and medium for color registration control of electronic axis gravure printing machine based on set member identification

Abstract

The invention discloses a color registration control method, system and medium of an electronic shaft gravure printing machine based on set member identification. The method includes: obtaining the actual measurement error, and making a difference between the actual measurement error and the simulation result of the basic model to obtain the first residual difference; among them, the basic model is the relationship model between the color registration error and the control quantity; according to the actual control quantity, the preset residual with the smallest difference between the preset residual and the first residual is identified in the preset residual model set model, and determine the parameter values ​​in the preset residual model; wherein, the preset residual model is the relationship model between the preset residual and the control quantity; determine the color registration control model according to the basic model and the preset residual model; obtain Color registration error, and control the printing plate roller to run according to the model control amount according to the color registration control model. The embodiments of the present invention can further reduce the color registration error, make the model result closer to the actual result, and can be widely used in the field of printing control.

Description

technical field [0001] The invention relates to the field of printing control, in particular to a color registration control method, system and medium for an electronic shaft gravure printing machine based on set-member identification. Background technique [0002] The electronic shaft gravure printing machine is a roll-to-roll printing system. During the printing process of the electronic shaft gravure printing machine, the roll paper is transported out from the unwinding part, and the tension controller of the paper feeding part keeps the roll paper force in a stable state. Horizontal, and then send the web into the multi-color printing section, the gravure cylinders in each printing unit will print different patterns on the web in turn, and finally the web is convoluted to the paper outlet, and each color group is composed of different patterns. The printed pattern will eventually form the desired complex multi-color pattern. Among them, the position asymmetry of the pat...

Problems solved by technology

A traditional modeling method is based on the feedforward decoupling fuzzy PD control modeling of the system mathematical model, but it is limited by the discretization of high-order equations, so the model cannot completely decouple the system; another modeling The method is directly decoupled PD modeling. Although its model accuracy is better than the previous method, it has shortcomings in eliminating noise and disturbance effects.
