Printing process of UV flash three-dimensional pyrography

Abstract

The invention discloses a printing process of UV flash three-dimensional pyrography, which is used for printing on cartons. The printing process comprises the following steps of (1) plating silver: partially plating silver on the cartons; (2) calibrating: determining that the gilding position and the printing position are kept consistent through the registration of a positioning film; (3) printing patterns: partially printing patterns on the cartons with printing ink, wherein the registration error of the printing patterns is less than or equal to 0.05 mm; (4) performing matte printing: performing matte printing on full pages of the cartons; and (5) glazing: registering gilding and printing contents, and glazing with UV varnish. The printing process of the UV flash three-dimensional pyrography has the following advantages that (1) the visual stereoscopic effect of the surfaces of the graphic cartons is good, and the display effect is good; (2) the UV flash three-dimensional pyrography has a strong concave-convex feeling.

Description

technical field [0001] The invention relates to a printing process, in particular to flashing three-dimensional hot stamping printing on a color box. Background technique [0002] The printing industry is a very complex industry. It not only has many internal sub-sectors, but also involves many related industries. It can be said that it is a huge industry system, but also an industry system with a long history. Since the invention of printing in ancient China, printing technology has gradually penetrated into production and life, and has been developed and expanded step by step, forming a huge industry. Although China has become a major printing country, its per capita printing consumption is only 1 / 10 of that of developed countries, its industrial structure is unreasonable, its structural contradictions are prominent, its research and development foundation is weak, its technical innovation is insufficient, its technical equipment, and the quality of its practitioners need...
