Digital cold-stamping gold film and production process thereof

Abstract

The invention provides a digital cold-stamping gold film, comprising an information carrier, a release layer on the first surface of the information carrier, an A pressure sensitive adhesive layer bonded on the release layer, a surface paper covered on the A pressure sensitive adhesive layer, a B pressure sensitive adhesive layer on the second surface of the information carrier, a silicone oil layer bonded on the B pressure sensitive adhesive layer and a bottom paper covered on the silicone oil layer. The digital cold-stamping gold film is characterized in that peel strength between the surface paper and a film carrier is F1, peel strength between the film carrier and the bottom paper is F2, peel strength between the film carrier and a stamping substrate is F3, and the relationship among F1, F2 and F3 is that F2<F1<F3. The invention has the following advantages: through usage of the digital cold-stamping gold film, digital stamping can be finished through the five steps consisting of cutting, film pasting, peeling, cold pressing and waste discharge, high temperature is not needed in the process of stamping, investment for equipment is low, process flow is short, operation is simple, and the digital cold-stamping gold film is applicable to stamping of temperature-sensitive materials in personalized service agencies having demands for variability, demand orientation and individuation and to processing of personalized labels.

Description

technical field [0001] The invention relates to a digital cold foil stamping film and a production process of the film. , Indoor and outdoor large-scale inkjet printing, hot stamping or personalized label processing, etc., belong to the field of digital post-press production. Background technique [0002] With the improvement of the national economy and the development of the printing and packaging industry, people require high-end, exquisite, environmentally friendly and personalized product packaging. In the post-press processing of packaging products, the hot stamping process has unique surface finishing effects has always been loved by people. Hot stamping has three main functions. One is surface decoration. The hot stamped text presents a strong metallic luster, bright colors, and never fades. Especially hot stamping silver embellishes the surface of printed matter with its magnificent, exquisite and elegant decoration, enhancing It improves the artistry of printed pr...

Problems solved by technology

[0009] Technical disadvantages of hot stamping: hot stamping plate making process is complex, time-consuming, energy-consuming, high pollution, and traditional hot stamping operation flexibility is poor

[0014] The technical disadvantage of cold stamping: when coating the adhesive on the surface of the printed matter, if offset printing is used, a printing plate must be prepared; if printing adhesive is used, a special UV flatbed printer must be used. The price of this flatbed printer exceeds one million, and UV The curing equipment has ozone emission, ultraviolet rays are harmful to the human body, the operation risk is high, and the pressing, winding / unwinding operations are complicated

[0020] Technical disadvantages: the hot stamping film must be a special anodized aluminum material with no hot melt adhesive on the back, the cost of toner as an adhesive between the hot foil and paper is high, and it is not environmentally friendly; the toner cartridge in laser hot stamping needs to be directly attached to the substrate Contact, the substrate is limited to thinner uncoated paper, and it is impossible to bronzing substrates such as coated paper, hard cardboard, film, plastic sheet, etc.; it is impossible to selectively print / copy graphics Partial hot stamping; large format hot stamping is not possible

[0025] Technical disadvantages: Due to the frequent work in high temperature and high pressure environment, the service life of thermal printing head is short, the replacement cost is high, and expensive customized anodized aluminum must be used, so this process not only has high equipment price (original imported equipment price is 12W) and high maintenance and use costs

[0026] Obviously, the limitations of the above two digital hot stamping processes in terms of equipment costs, raw material prices, hot stamping materials and formats cannot meet the needs of most personalized service agencies for miniaturization and low investment at this stage
