An offset press UV varnishing method

Abstract

The invention relates to the field of printing, in particular to a UV glazing method for an offset printing machine. It includes the following steps: selecting the liner paper and the original, cutting off the area of ​​the liner paper corresponding to the non-image part of the printed matter to form a hollow, installing the color sequence printing plate, and laying the cut liner paper in a corresponding manner On the printing area on the blanket, install the liner paper together with the blanket on the blanket cylinder and fix and lock it, then set the light ink, UV lamp, adjust the offset printing machine and print, UV on the printed matter Varnish. The invention provides a high-efficiency glazing method for performing UV three-dimensional effect of an offset printing machine by hollowing out the liner paper, and solves the problems that the existing offset printing machine glazing method has complicated procedures and cannot print three-dimensional effects.

Description

technical field

[0001] The invention relates to the field of printing, in particular to a UV glazing method for an offset printing machine. Background technique

[0002] Offset printing has many advantages such as fast printing speed, relatively stable printing quality, and short printing cycle. Offset printing is a type of lithographic printing, that is, a printing method in which the graphics on the printing plate are transferred to the substrate by means of rubber (rubber cloth). The blanket plays an irreplaceable role in printing. The blanket can well compensate for the unevenness of the surface of the substrate, fully transfer the ink, and reduce the transfer of water from the printing plate to the substrate.

[0003] When producing products on offset printing machines, there are two existing methods that can meet the full-page UV coating requirements. One is to use a flexible resin plate for coating, and the other is to use a method of dividing the blanket for coating...
