Problems solved by technology

[0006] However, the traditional laser pattern imprint transfer needs to use high temperature and high pressure to complete the production of laser film first, and then use film-to-film transfer, which leads to the following disadvantages: 1. Long process route, low precision, low efficiency and high cost ; 2. Only the laser embossing transfer of continuous general laser patterns can be carried out; 3. The shadow problem is caused by lamination and overflowing glue around the laser pattern, and the surface quality of the laser positioning embossing transfer pattern is not high

Abstract

The invention discloses a laser pattern positioning impression transfer method. The method comprises the following steps: carrying out positioning printing treatment of a substrate through an intermedium printing device to obtain an intermedium position-printed substrate; allowing the intermedium position-printed substrate to go through a transparent roller and a bearing roller to make the intermedium on the substrate contact with a mother matrix of the transparent roller in order to impress a laser pattern on the medium in a positioning manner; and curing the substrate impressed with the laser pattern through an ultraviolet curing device to obtain a laser pattern laminae. The method has the advantages of realization of the point-to-point position special edition pattern impression transfer, elimination of the ghost phenomena of four edges of the transferred pattern, increase of the impression transferred pattern precision, and improvement of the surface quality of the pattern.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a laser pattern positioning imprint transfer method. Background technique [0002] At present, the laser pattern making method is realized by coating, molding (high temperature, high pressure), or made into a laser film, and then the laser effect is realized on the printing material by means of transfer, hot stamping, cold stamping, etc. The specific process route is as follows: [0003] One of the traditional laser pattern imprinting transfer production processes: the process steps are in order of selecting a specific film such as PET → coating a release agent on the film → molding graphics on the release layer at high temperature and high pressure → making a laser film → on the laser film Glue application→composite the laser film and printing material→peel off the laser film→transfer the graphic and laser texture layer to the printing material. [0004] The second tradition...
