Production method of gold stamping film

Abstract

The invention discloses a production method of a gold stamping film. The production method comprises the following steps that a substrate layer is coated with a release layer, the release layer is coated with a color printing layer, the color printing layer is coated with a mould pressing layer, and electroplating is carried out on the mould pressing layer to form an electroplated layer. A process of manufacturing the mould pressing layer comprises the following steps that a holographic embossment laser mould pressing plate is manufactured, graphic and text information is engraved on a nickel plate by using a laser holographic engraving technology, and the surface of the nickel plate is processed to manufacture a mould pressing metal plate; and positioning and mould pressing are carried out, an embossment laser transparent film is manufactured, and the set register precision is kept according to the used plate cylinder number. Color printing, the platinum embossment technology and the gold stamping technology are combined, the personalized 3D platinum embossment effect of container packaging is achieved through technological treatment of printing, mold pressing and electroplating, continuous printing and hot stamping are achieved, and large-scale production is facilitated. The method can be widely applied to the technical field of product packaging.

Description

technical field [0001] The invention relates to the technical field of product packaging, in particular to a production method of bronzing film. Background technique [0002] Hot stamping film has a colorful 3D effect and is widely used in the field of hot stamping decorative anti-counterfeiting packaging. It has a good color platinum relief effect, strong anti-counterfeiting performance, excellent wear resistance and hot stamping cutting performance, and meets the requirements of card, wine packs and cigarette packs. , gifts, cosmetics packaging and other high-end product requirements. The current bronzing film is common printed hot stamping film and cold stamping film, mostly gold or silver, and the newer one is holographic hot stamping film, but none of them can present the color platinum embossing effect. [0003] If manufacturers want to achieve partial color platinum relief 3D effects, they can use composite photoresist film or thermal transfer photoresist film, but t...

AI Technical Summary

Problems solved by technology

The current bronzing film is commonly printed hot stamping film and cold stamping film, mostly gold or silver, and the newer one is holographic bronzing film, but none of them can present the color platinum embossing effect

[0003] If manufacturers want to achieve partial color platinum relief 3D effects, they can use composite photoresist film or thermal transfer photoresist film, but this composite film has great limitations in application, lack of three-dimensional effect, and poor anti-counterfeiting

This method is complex and costly

There is a way to use thermal transfer photoresist film, and the subsequent printing process needs to use a large amount of white ink to cover the laser part, the cost and process are complicated
