Problems solved by technology

Hot stamping and concave-convex process are two different processes in the later stage of printing. Hot stamping is to heat the hot stamping plate to above 100 ℃, and transfer the anodized aluminum of the hot stamping transfer layer to the printed matter, while the concave-convex process is to use the concave mold and the convex mold To deform the printed matter to have a three-dimensional convex-c

Embodiment Construction

[0015] Such as figure 1 Among them, a bronzing embossing one-time forming method comprises the following steps:

[0016] 1) Make the die 21, the punch 22 and the stamping plate 23 on the upper die 1 and the lower die 2 of the same group;

[0017] 2) heating the upper mold 1 and / or the lower mold 2 to a temperature for bronzing;

[0018] 3) A heat insulating layer 3 is provided between the concave mold 21 or the convex mold 22 and the printed matter 5;

[0019] 4) A hot stamping transfer layer 4 is set between the hot stamping plate 23 and the printed matter 5;

[0020] Through the above steps, one-time molding of hot stamping and concave-convex processing is realized.

[0021] The heat insulation layer is a thin material that can withstand a temperature of 80°-120°C and has elasticity.

[0022] The heat insulation layer is rubber or rubber cloth, and the thickness of the heat insulation layer is usually below 1mm. After testing, the setting of the heat insulation layer ca...

Abstract

The invention relates to a bronzing and concave-convex one-time forming method, which comprises the following steps: 1) producing a female die, a male die and a bronzing on a same group including an upper die and a lower die; 2) heating the upper die and/or the lower die to the temperature for bronzing; 3) arranging a thermal insulation layer between the female die or the male die and a printed product; and 4) arranging a bronzing transfer printing layer between the bronzing plate and the printed product; and realizing bronzing and concave-convex one-time forming through the above steps. By adopting the bronzing and concave-convex one-time forming method, the bronzing process and the concave-convex process can be merged, the printing quality is improved, and the adoption of the thermal insulation layer can avoid the problems of flower pulling and fogging of printing ink or decline in bright degree of color in concave and convex positions due to the temperature reason.

Description

technical field [0001] The invention relates to a post-treatment process for printed matter, in particular to a bronzing concave-convex one-time forming method. Background technique [0002] With the improvement of people's living standards, product packaging has become more and more demanding and more exquisite. Many products use bronzing and embossing processes to enhance the aesthetics of the products. Hot stamping and concave-convex process are two different processes in the later stage of printing. Hot stamping is to heat the hot stamping plate to above 100 ℃, and transfer the anodized aluminum of the hot stamping transfer layer to the printed matter, while the concave-convex process is to use the concave mold and the convex mold To deform the printed matter to have a three-dimensional convex-concave shape, the printing factory usually uses a fully automatic hot stamping machine for processing. The hot stamping and embossing processes at different positions on the same ...
