Cold perm process and uv glue used in this process

Abstract

The invention provides a cold ironing technology and UV glue applied to the technology. The technology comprises the steps that 1, the UV glue is printed to the portion, needing cold ironing, of a printed material and the tone and hue of an electrochemical aluminum foil film easy to strip are adjusted according to the hue needed by a product; 2, opposite pressing is conducted on the electrochemical aluminum foil film easy to strip and the printed material so that the electrochemical aluminum foil film easy to strip and the printed material can adhere together through the UV glue; 3, the portions, not adhering to the printed material through the UV glue, of the electrochemical aluminum foil film easy to strip are stripped and an aluminum layer easy to strip of the electrochemical aluminum foil film easy to strip which adheres to the printed material through the UV glue is transferred to the printed material; 4, the UV glue is solidified through illumination of an ultraviolet ray lamp. According to the cold ironing technology and the UV glue applied to the technology, the technology process is simple, the ironing and printing speed is high, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of printing, in particular to a cold stamping process and a UV glue used in the process. Background technique [0002] With the development of social urbanization, technology, and humanization, the printing industry has developed vigorously. More and more packaging boxes for food, cosmetics, and industrial products need to be printed and finely stamped. In recent years, domestic printing manufacturers have successively introduced and purchased A number of newly developed cold stamping equipment, the cold stamping process can stamp fine lines, and the difference in dots has been well received by the industry. The manifestation of problems such as complex and unstable and high loss costs. [0003] At present, the domestic cold perm technology mainly adopts two methods: one is the ordinary cold perm self-drying glue matching self-drying cold perm anodized aluminum foil film; the other is to use UV adhesive and UV cold p...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a cold stamping process, which first peels off the easy-peelable anodized aluminum foil film, and then cures the UV glue, effectively solving the problem of ordinary self-drying glue sticking to the bottom, and its process is simple and the stamping speed is high. Fast, and in actual production, the anodized aluminum foil film can be moved differently from the substrate, which greatly saves the amount of anodized aluminum foil film used and reduces production costs
