Problems solved by technology

[0005] The disadvantages of the above patents are: it can only be used to improve the inherent color and metallic feeling of gold and silver, and improve the product grade of brush products, but the structure of the gold and silver printing layer is poor in stability, and there is no protective measure for the gold and silver printing layer. The service life of the gold and silver printed matter produced is short. Once the gold and silver printed layer is damaged, the corresponding object will become a waste product, which will easily cause a large amount of social garbage and is not conducive to environmental protection.

Abstract

The invention discloses a gold and silver printing method which includes the steps of material preparation, auxiliary material addition, plate making, printing and curing. The process is simple, printing efficiency is high, various protective component structures are added to a gold and silver printing layer, and the service life of the gold and silver printing layer is greatly prolonged.

Description

Technical field [0001] The invention relates to the field of gold and silver printing, in particular to a gold and silver printing method. Background technique [0002] At present, both producers and users are paying more and more attention to the outer packaging of products, and the market demand for various high-end packaging and personalized packaging is also increasing. Under this trend, the packaging and printing field is constantly developing new processes and new materials to meet the needs of the packaging market. [0003] The primary color gold and silver printing is a printing technology in which the color that appears on the printed matter after printing is basically the same as the actual color purity of the corresponding gold and silver powder. When the currently used offset presses are used for printing gold and silver inks, due to the limitation of the printing principle of water-oil separation, the particle size of the gold and silver powder in the gold and silver ...
