Method of forming notched color fine pattern on the surface of glass product

Abstract

A method of forming colored intaglio fine patterns on the surface of glass, suitable for the manufacture of art glass and glass products. Its method is: (1) color image manuscript is made digital image file. (2) AM screening with a raster image processor. (3) Use a digital jet printer to print color negative images on the surface of glass and glass products. (4) Carry out chemical intaglio treatment on glass and glass products with color negative image spray-printed patterns. (5) Remove the negative image pattern ink. (6) Use a digital jet printer to print a color positive pattern at the position of the original negative pattern. The advantages of the invention are: (1) The color and light and shade levels of the color original image can be well reproduced on the surface of glass and glass products, and the original original can be reproduced faithfully. (2) Observing from the back of the spray-printed glass, the color of the pattern is exceptionally bright, vivid and firmly adhered, which is suitable for daily use conditions. (3) Suitable for mechanization and batch production. (4) There is no need for negative film and printing plate, and the processing cost is low.

Description

technical field [0001] A method of forming photo-effect colored intaglio fine patterns on the surface of glass and glass products. The invention relates to a method of forming a color negative image pattern on the surface of glass and glass products (hereinafter collectively referred to as glass) by using a digital jet printing device, and then performing chemical surface treatment to produce intaglio points on the glass surface, and then printing a color positive pattern on the intaglio position. Like a pattern, it is a method of forming a photo-like color intaglio fine pattern on the surface of the glass. Background technique [0002] The so-called art glass, which forms various patterns on the glass surface, is getting more and more applications in fields such as architecture, decoration, furniture, daily necessities, and artwork in recent years. At present, the manufacturing methods of art glass mainly include color printing method, etching printing method, sandblasting...

AI Technical Summary

Problems solved by technology

The oil-based or water-based pigment or dye ink used in digital jet printing machines has poor bonding force with glass, and the pattern is not firmly attached, and sometimes it cannot even form a pattern

Roughening the glass surface (such as sandblasting) and using special ink before printing can improve the bonding force, but the degree is limited, and the fine pattern will be blurred, the effect will be poor, and it is not practical.
