Roller painting reaction and reverse glazing combined process

Abstract

The invention discloses a roller painting reaction and reverse glazing combined process, which comprises the following steps of printing four-color ink on a substrate in sequence according to a color sequence; partially printing base coat on a presswork by a printing color cell and forming an image-text region A through partially printing the base coat; fully drying or solidifying; coating the base coat on the presswork by a glazing set I and forming an image-text region B through coating the base coat; fully drying or solidifying; coating face oil on the presswork by a glazing set II and forming two reverse glazing regions at the image-text region A and the image-text region B after coating the face oil; fully drying or solidifying. According to the process, two or more than two reverse reaction vision effects are implemented by an on-line printing machine, the effect of matt vision of different figures can be generated in more than two image-text regions, on the one hand, the variety of the figures on products is increased and the packaging level of the products is improved, and on the other hand, a certain anti-fake effect is implemented.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a composite reverse glazing process that can produce two or more shrinkage effects and has good bronzing processability. Background technique [0002] Glazing is a common processing technology in printing, which is to coat a layer of colorless and transparent paint on the surface of the printed matter. After leveling, drying and calendering, a thin and uniform transparent and bright coating is formed on the surface of the printed matter. Floor. Through the glazing process, the appearance of the printed matter can be enhanced, the performance of the printed matter can be improved, the grade of the product can be improved, and the added value can be increased. [0003] With the increasing level of people's appreciation, the traditional glazing process that only brightens the entire surface or part of the printed matter can no longer meet people's needs, and the reverse glazing pr...

Problems solved by technology

Compared with the traditional double-light process, the reverse glazing has the advantage that the partial primer operation is performed by the PS plate on the printing color group of the offset printing machine, which ensures the overprint accuracy of the partial glazing and satisfies the complex local glazing requirements. The disadvantage is that the effect of the process is single, and two types of shrinkage effects cannot be processed on the same layout at one time; the bronzing processability is not good
