A high-precision plate-free hot stamping process

Abstract

The invention discloses a high-precision plate-free hot stamping process, which includes the following preparation steps: first, designing a hot stamping document; second, making a closed oil layer document in reverse; third, installing it on a flexible glazing unit of a UV offset printing machine; fourth, Prepare thermoplastic varnish, and then apply full plate on the bronzing document, and print and apply thermoplastic varnish layer to the product; fifthly, prepare inert sealing oil, and then apply full plate on the sealed oil layer file, and print and apply inert to the product Seal the oil layer; the sixth is to make hot stamping foil, which includes the vacuum aluminized layer, PET film layer and varnish layer that are stacked in sequence; the seventh is to install the hot stamping plate, and maintain the heating temperature of the hot stamping plate at 110°C through the control program of the hot stamping machine Between ~130℃, the pressure of the hot stamping plate is adjusted to 30~40t to carry out the hot stamping process. Through the above method, the present invention combines hot stamping and cold stamping, realizes the improvement of stamping accuracy, reduces the production cost of stamping, and enriches the present There are bronzing process methods.

Description

technical field [0001] The invention relates to the technical field of hot stamping, in particular to a high-precision plate-free hot stamping process. Background technique [0002] Hot stamping is a processing technology of post-press decoration. It is to attach colored anodized aluminum to the printed matter by heating or transferring to form a special metal effect, thereby improving the grade of the printed matter. [0003] In the prior art, the commonly used equipment for bronzing process is mainly divided into: flat stamping machine, round stamping machine, and round stamping machine. These three methods are hot stamping, and different bronzing contents require different moulds. Therefore, it will require a certain amount of time to adjust the position every time the order is cut to ensure the accuracy and the effect of hot stamping. However, due to the influence of hot stamping equipment, the precision of hot stamping is limited. [0004] Cold stamping process is a ne...

Problems solved by technology

[0003] In the prior art, the commonly used equipment for bronzing process is mainly divided into: flat stamping machine, round stamping machine, and round stamping machine. These three methods are hot stamping, and different bronzing contents require different moulds. Therefore, it will require a certain amount of time to adjust the position every time the order is cut to ensure the accuracy and the effect of hot stamping. However, affected by the hot stamping equipment, the precision of hot stamping is limited

[0004] Cold stamping process is a new type of hot stamping technology developed with the progress of the market. Hot stamping combined with printing has good comprehensive performance, more accurate hot stamping accuracy, can beautify fonts and can handle details more perfectly; but cold stamping needs It is very expensive to invest in special cold stamping equipment, and the special cold stamping foil and cold stamping glue make the price of cold stamping twice as much as the traditional price; therefore, there is an urgent need for a hot stamping process with high stamping precision and low production cost
