Example Embodiment

[0029] Embodiment 1: A combined process of roller coating reaction and reverse glazing, the process is completed online by a printing machine, the printing machine has five printing color groups and two glazing groups, and four of the five printing color groups in the printing machine. According to the requirements of the printing color sequence, the transfer of the four-color ink of yellow, magenta, cyan and black is completed, so that the effect of color printing is produced on the surface of the substrate (such as paper). The remaining one printing color group is used for the coating of the primer in the graphic area A, the glazing unit I is used for the coating of the primer in the graphic area B, and the glazing unit II is used in the entire graphic area A and graphic area. Coating top oil on B, in this way, through the reaction between the base oil and the top oil, the wetting performance of the top oil in the graphic area of ​​the printed base oil and the blank area of ​...

Example Embodiment

[0041] Embodiment 2: The specific steps of this process are:

[0042] 1) Print four-color inks in sequence on the substrate according to the color sequence, and obtain a printing layer with color effects on the substrate;

[0043] 2) The local primer coating of the printed matter is carried out by a printing color group, and the coating of the local primer constitutes the graphic area A;

[0044] 3) Fully dry or cured;

[0045] 4) The anilox roller of the glazing unit I is used to coat the base material again with the base oil of the printed matter to form a new graphic area B, and the graphic area A and the graphic area B do not overlap;

[0046] 5) Fully dry or cured;

[0047] 6) The anilox roller of the glazing unit II is used to coat the surface oil of the printed matter on the substrate to form a graphic area C. The graphic area A after the coating of the top oil forms a reverse glazing area A, and the coated surface A reverse glazing area B is formed at the graphic ar...

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...
