subject: Packaging Converting Special Printing Stamping Technical Overview [print this page] Holographic hot stamping technology is currently being certified in the world a safer and successful means of forgery, holographic hot stamping process high-volume applications hologram, hot stamping in the substrates are very thin hologram, and the substrate melting as a whole, rather than on Print Patterns and colors off by each other, get a good visual effect. According to the different stamping technique, holographic hot stamping can be divided into 3 types, namely low-speed holographic hot stamping, hologram stamping fast and high-speed random version of positioning holographic hot stamping. High-speed positioning holographic hot stamping technology which most demanding, most security efforts need to ensure higher productivity, will complete a hologram, accurately stamping the specified location, the positioning accuracy of not less than 0.25mm. Hologram positioning hot stamping with the appropriate security design, technology specific, its positioning through the use of holographic probe, precise control of the hot stamping foil, hot stamping and high quality, has worldwide reach a consensus. Because holographic hot stamping foil manufacture difficult, manufacturers less complex process, so costly.
Cold stamping technology is a new stamping techniques, without using the heating of the metallic silver version, but will bond decorative graphics painted directly on to foil attached to the printed surface. Cold Stamping usually rotary manner forming process, hot stamping speed, but the gilt surface effects and strong difference, it still needs polishing or coated printing process. Cold stamping technology, low cost, saving Energy High production efficiency. Tobacco Factory market today lifted some boxes of paper packets Article Package Switch to an alternative color film pack to reduce packaging article box cost. Use cold stamping technology, you can make a similar paper and film hot stamping effect, increasing the attractiveness of cigarette packets.
First printed in the printing industry after hot and Design New ideas. India is the first after the first hot white card in silver foil stamping on paper, then foil stamping the surface of the printed graphic is a large stamping area of technology. Such processing methods usually round flat or rotary press Stamping Machine , Stamping line contact when the pressure means, in large stamping, the stamping platen not appear when the bubble, stamping surface is very smooth, while full version stamping will not increase the load on the machine.
Three-dimensional hot stamping is the use of corrosion or carving stamping and embossing to create a graphic model up and down with the yin and yang die, stamping and embossing to achieve a complete process. This process simultaneously hot stamping and embossing, to reduce the processing procedure generated by the waste are not allowed to overprint, improved productivity and product quality. Often used three-dimensional hot stamping hot stamping and embossing a high-resolution material, in different angles graphics can present different colors to achieve the desired anti-copy and anti-counterfeiting features. Photo subtle levels of cover to avoid tampering and counterfeiting documents. Three-dimensional stamping platen can be used, round mild rotary hot foil stamping press Die Cutting Machine , Gilt sculptures using brass corrosion Zitong version or edition. Corrosion of copper version for flat stamping, life is short, usually 10 million, while the carved brass version of the service life of 100 million can apply to live a long version, but good quality gilt.
