Hot gold foil

Abstract

The invention relates to the technical field of printing and particularly relates to a hot gold foil. The hot gold foil comprises a base film layer, a release layer on the base film layer, a colour layer on the release layer and an aluminium coated layer on the colour layer, wherein an ink layer is arranged at the bottom of the aluminium coated layer, during hot stamping, firstly, a worker can lay one side, provided with the ink layer, of the hot gold foil onto the surface of a to-be-printed object, through heating and pressing of a gold stamping machine and a hot stamping template, the metal foil of the hot gold foil is printed on the surface of the to-be-printed object, during hot stamping, the ink layer provided by the invention is positioned in a high temperature environment with the temperature of more than 100 DEG C, at the moment, the stickiness of the ink layer is increased after melting by heating, and printing onto the to-be-printed object is achieved while the aluminium coated layer and the base film layer are peeled off. With pressure release, the ink layer is quickly cooled and solidified, and the aluminium coated layer is firmly adhered onto the to-be-printed object, so that the metal foil of the hot gold foil is firmly adhered onto the to-be-printed object. Therefore, due to the use of the hot gold foil for gold stamping, the gold stamping process and steps are simplified, the production efficiency is improved, and the product cost of manufacturers is lowered.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a bronzing paper. Background technique [0002] Hot stamping, also known as hot stamping, is a printing decoration process. At present, the hot stamping technology is to heat the metal printing plate, apply foil, and emboss golden characters or patterns on the printed matter. With the rapid development of hot stamping foil and packaging industry, the application of metal foil hot stamping is becoming more and more extensive. Metal foil hot stamping foil mainly uses heating and pressure to transfer patterns or characters to the surface of the hot stamping material. To complete this process, you need a hot stamping machine, hot stamping templates (such as zinc plates, copper plates, silicone plates, etc.) engraved with special text or patterns, heated to the required temperature, transferred the required pressure and maintained for the corresponding time. But because the existi...

Problems solved by technology

But because the existing hot stamping paper itself is not sticky, therefore, when hot stamping, need to coat one deck hot stamping paste or hot stamping glue on the surface of substrate, the shape and pattern, text of hot stamping glue on the substrate surface The same shape, and then the hot stamping paper is covered on the surface of the substrate for hot stamping, so that the metal foil on the hot stamping paper adheres to the surface of the substrate

Therefore, there are following deficiencies in the existing hot stamping paper, (1) the existing hot stamping paper itself has no stickiness, and when the hot stamping paper is hot stamped, it needs to be coated with a layer of hot stamping paste or hot stamping glue on the substrate, which will It will increase the complexity of the operation, the operation is very cumbersome, and the work efficiency will be reduced, especially for the hot stamping of complex curved surfaces. If the hot stamping glue is not evenly applied, it will lead to false hot stamping of the metal foil and easy to lose gold

(2) With this hot stamping method, the metal foil on the surface of the substrate is not strong enough, and the metal foil hot stamping is not solid or easy to lose gold, easy to fall off

For inorganic substrates with high hardness such as glass, ceramics, and stainless steel, since the bronzing paste of bronzing paper cannot be well bonded to these inorganic substrates, it cannot be applied to the bronzing of these inorganic substrates, thus making bronzing The range of applications of paper is very limited
