Problems solved by technology

[0002] Paper packaging boxes for food, cosmetics, and medicines that are commonly used in our lives are usually printed, die-cut, and folded by color printing machines. One decorative effect, such as partial particle frosting effect and glossy effect, or matte and glossy effect, if you want to add a third effect, you must print for the second time or achieve it through post-press equipment, and the printed matter is in the second printing or finishing In the process of printing, the problem of inaccurate printing is prone to occur, the production efficiency is low, and the cost and defective rate are high

Abstract

The invention relates to a method for realizing three kinds of surface finishing effects through one printing on one printing device. The device adds an anilox roller glazing unit between two adjacent printing units, that is, it is connected after the glazing unit. The printing unit, the method includes: S1, respectively arranging the first glossy printing plate and the second glossy printing plate on two adjacent printing units before and after the anilox roller glazing unit; S2, completing UV ink printing on the surface of the substrate ; S3, printing the first UV varnish in the first area with the first glazing plate, and UV curing; S4, coating the second UV varnish on the surface of the substrate through the anilox roller glazing unit, the first After the UV varnish reacts with the second UV varnish, a particle frosting effect is formed in the first area, and a bright light effect is formed in areas other than the first area, which are cured by a curing device; S5, through the second printing plate on the surface of the substrate Print a layer of third UV varnish on the second area to make the substrate form a matte effect on the second area, and perform UV curing.

Description

technical field [0001] The invention belongs to the technical field of ink printing, in particular to a printing process for decorative cardboard and cartons. Background technique [0002] Paper packaging boxes for food, cosmetics, and medicines that are commonly used in our lives are usually printed, die-cut, and folded by color printing machines. One decorative effect, such as partial particle frosting effect and glossy effect, or matte and glossy effect, if you want to add a third effect, you must print for the second time or achieve it through post-press equipment, and the printed matter is in the second printing or finishing In the process of printing, the problem of misregistration is prone to occur, the production efficiency is low, and the cost and defect rate are high. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a process method for achieving three effects of matte,...
