Problems solved by technology

[0003] No matter gravure printing, flat printing, flexo printing, screen printing or plateless digital printing, in order to highlight the metallic luster and luxurious and magnificent characteristics, at the same time create a strong contrast on the printed product screen, add bright colors to obtain a crystal clear eye-catching effect, especially on the packaging of cigarette labels, wine labels, gift boxes, etc., the bronzing process is generally used to achieve the effect that other processes cannot achieve at all
However, as far as the current hot stamping process is concerned, regardless of the flat pressing method, or the round pressing method, or the round pressing method, it must be cut into a single sheet, which has a long production cycle and low efficiency.
For products with large batches, although the use of gravure printing can effectively solve the problems of poor stability and low production efficiency, if the subsequent work is done with hot stamping, it will seriously restrict production efficiency, increase production costs, and deteriorate stability.

Abstract

A substitute method for gilding includes such steps as coating the parting paint on PET film, baking for solidifying, vacuum aluminizing, coating protecting paint with gilding pattern plate, baking for solidifying, immersing in alkali solution for removing aluminium, baking to obtain transfer film, coating adhesive, sticking onto substrate to obtain composite paper, stripping the film to obtain transfer paper, and printing with said transfer paper.

Description

technical field [0001] The invention belongs to a method for replacing bronzing, and in particular relates to a method for replacing bronzing by adopting an aluminum washing process to make transfer paper and using a film printing aluminum process for composite printed matter. Background technique [0002] The traditional bronzing process is: using anodized aluminum (also metal foil, powder, color foil, etc., but currently the most important is anodized aluminum) material, pre-engraving the pattern to be hot stamped on the hot stamping plate, when the hot stamping plate with the When the heating plate is heated up to a certain temperature, the anodized aluminum film and the substrate are imprinted, and the adhesive layer, metal aluminum layer and color layer attached to the anodized aluminum film are transferred to the substrate by the action of temperature and pressure. , forming bright, rich metallic effect patterns. [0003] No matter gravure printing, flat printing, fle...
