Abstract

The invention discloses a coding type back printing automatic color register method. The method is implemented by a coding type back printing automatic color register device. The coding type back printing automatic color register device comprises a printing roller shaft, wherein the printing roller shaft is connected with a motor; the end of the printing roller shaft is connected with an encoder; a motion controller is connected with a coding machine; an automatic color register controller is further connected with a photoelectric head and the motion controller respectively; the coding machine and the photoelectric head are arranged on one straight line along the running direction of a material film. By using the coding type back printing automatic color register device, color codes are printed on the back sides of printed patterns, one color code is printed on the same phase once a printing roller rotates by a circle, and the printed color codes are completely consistent with front-side printed patterns, so that the problems of difficulty in detecting printed color codes during automatic color register of a wallpaper printer, high cost of flexible printing back printed color codes and complexity in operation in the prior art are solved by taking the printed color codes as reference color codes of color register.

Description

technical field

[0001] The invention belongs to the technical field of wallpaper printing and embossing, and in particular relates to an automatic color registration method for coded back printing. Background technique

[0002] In the process of traditional wallpaper printing, due to the particularity of the wallpaper industry, the color mark cannot be printed on the front of the substrate. If the color mark is printed on the front of the substrate, the color of the front color mark is too close to the color of the paper, and it is impossible to use the existing Standard photoelectric eye detection; the front color code is easy to interfere with the existing color code; when in the embossing part, the material is foamed, and the photoelectric eye cannot detect it; the color code is printed on the front, only on the edge of the material film , the existing materials have serious ruffles, which affect the printing accuracy.
