Transferring method and device for positioning and non-positioning heat protruding gold stamping

Abstract

The invention discloses a transferring method and device for positioning and non-positioning heat protruding gold stamping. According to the method, in the manner of gravure printing, screen printing or offset printing coating, UV heat protruding transferring printing ink is printed at the position needing gold stamping; and after UV curing, a high temperature resistant colloid soft roller capable of being heated and a pressure bearing roller are used for performing combined pressing, a metal material on metal foil is transferred onto the surface of the cured UV heat protruding transferring printing ink in a wrapping manner, and an effect similar with heat protruding gold stamping is formed. According to the transferring method and device for positioning and non-positioning heat protruding gold stamping, compared with heat protruding gold stamping, no gold stamping plates need to be manufactured in the process, 78.5% of hot stamping cost can be saved under the same printing amount, the process cost can be greatly saved, transferring of large-area exquisite patterns can be performed, and the problems of line break and the like can be avoided; and compared with cold stamping, the metal luster sense of the heat protruding transferring effect is higher, and the protrusion hand feel is achieved.

Description

technical field [0001] The invention relates to the field of hot stamping, in particular to a transfer method and device for positioning and non-positioning hot embossing hot stamping. Background technique [0002] At present, the bronzing methods on the market are mainly divided into two types: hot stamping and cold stamping. Hot stamping can achieve two effects of flat stamping and convex stamping. Its bronzing surface has a strong metallic texture and a gorgeous style. It is suitable for making small-area LOGOs, texts, and icons. The effect is very good, but when dealing with large-area patterns and fine-line patterns, problems such as broken lines, pasted plates, and incompleteness are prone to occur, the production efficiency is low, and the scrap rate is high. Expensive; cold stamping is a hot stamping effect achieved by printing cold stamping glue transfer, which can handle large areas of fine patterns and hanging net layers, but does not have a raised feel, and curre...

[0002] At present, the bronzing methods on the market are mainly divided into two types: hot stamping and cold stamping. Hot stamping can achieve two effects of flat stamping and convex stamping. Its bronzing surface has a strong metallic texture and a gorgeous style. It is suitable for making small-area LOGOs, texts, and icons. The effect is very good, but when dealing with large-area patterns and fine-line patterns, problems such as broken lines, pasted plates, and incompleteness are prone to occur, the production efficiency is low, and the scrap rate is high. Expensive; cold stamping is a hot stamping effect achieved by printing cold stamping glue transfer, which can handle large areas of fine patterns and hanging net layers, but does not have a raised feel, and currently all cold stamping equipment in the world cannot achieve precise jumping functions , can only realize full-page skipping of printing pages, and the non-cold stamping parts between printing pages cannot be utilized through precise skipping, the waste of cold stamping foil is large, and the metal texture is not as good as hot stamping

The existing hot embossing hot stamping technology is not conducive to the fine-effect bronzing of large layouts, and it is easy to produce broken lines, paste, incomplete, high reject rate, and the production cost of hot stamping plates and supporting resin film is very high; the existing cold stamping technology can only For flat ironing, no raised handle
