Example Embodiment

[0020] A. Printing pattern design; use a computer to draw a color-separated and layered printing pattern; divide the entire printing pattern into several areas (for accurate alignment during engraving);

[0021] B. Surface treatment: First use pigment (black asphalt paint or colored paint) to evenly smear the surface of the copper printing roller mold blank, with a thickness of 0.1-0.15mm. The function of the paint is to facilitate the observation of the engraving effect when used for engraving;

[0022] C. Engraving: Place the surface-treated copper printing roller die blank on the engraving table of the laser 3D engraving machine, and the computer will output the color-separated and layered printing pattern to the laser 3D engraving machine. The laser 3D engraving machine will print on the copper Carry out layered and step-by-step engraving on the roll mold blank; the specific layer-by-step engraving method is as follows:

[0023] a. Determine the baseline and starting point of car...

Abstract

The invention relates to a process for engraving a three-dimensional large-sized copper pattern roller by using laser, which comprises the following technological steps of: (A), designing a printed pattern; (B), processing the surface; (C), engraving; (D), detecting; (E), removing pigment on the surface; (F), polishing the surface; and (G), electroplating. The invention has the following advantages that: (1) the environment is protected, and the discharge of the waste liquid of chemicals does not exist in the entire engraving process; (2) the engraving accuracy is high, and the engraving quality is good; and (3) the labor strength is low, the efficiency is high, and time, labour and force are saved.

Description

technical field [0001] The invention relates to the field of embossing roller engraving technology. Specifically, it relates to a laser three-dimensional large-scale copper printing roller engraving process. Background technique [0002] At present, the engraving process of large copper flower rollers (printing rollers, embossing rollers, coating rollers) with a diameter of more than 0.8-1.5 meters and a length of more than 1 meter is a photocorrosion engraving process. The disadvantages of this engraving process are: The waste liquid produced in the photo-etching process will cause environmental pollution, and the engraving quality is not good enough, labor-intensive, time-consuming and labor-intensive. Contents of the invention [0003] The object of the present invention is to provide a laser three-dimensional large-scale copper flower roller engraving process for the above-mentioned shortcomings of the current large-scale copper printing photo-corrosion engraving proc...
