Gilding plate, gilding press and gilding method

Abstract

The invention discloses a gilding plate, a gilding press and a gilding method, wherein the gilding plate comprises a plate base; a holographic hot stamping area and a concave-convex gilding area are arranged on the plate base in a bulging manner; the distance between the holographic hot stamping area and the concave-convex gilding area is smaller than or equal to 25 mm; the center of the holographic hot stamping area is bulged to form a pot-bottom-shaped surface; and a downwardly sunk pattern is formed in the surface of the concave-convex gilding area. As the holographic hot stamping area and the concave-convex gilding area are arranged on the same plate base at the interval, holographic hot stamping and concave-convex gilding of electrochemical aluminum can be fulfilled in the same process, that is, the production efficiency is greatly improved; and meanwhile, as the distance between the holographic hot stamping area and the concave-convex gilding area is smaller than or equal to 25 mm, the temperature change between the holographic hot stamping area and the concave-convex gilding area is small, and the gilding effect is effectively guaranteed.

Description

technical field [0001] The invention relates to hot stamping printing technology, in particular to a hot stamping plate, a hot stamping machine and a hot stamping method Background technique [0002] In the post-press process of trademark processing, many products are inseparable from the combination of holographic hot stamping and text embossed hot stamping. Whether it is holographic hot stamping or text embossed hot stamping (with embossed metal effect), its purpose is mainly to enhance Product anti-counterfeiting function and text decoration function. The commonly mentioned holographic hot stamping includes positioning hot stamping and non-positioning hot stamping. The positioning hot stamping pattern is uniform and has anti-counterfeiting function. The non-positioning hot stamping pattern is distributed regularly, and the anti-counterfeiting effect is not good. This technology is mainly for positioning hot stamping. The traditional method is to separate the product to t...

Problems solved by technology

[0003] Usually in the production process, in order to improve the production efficiency and product qualification rate, it is necessary to reduce the processing steps as much as possible to achieve the best processing effect, while the traditional hot stamping process has to be separated because of the products of holographic hot stamping and text embossing hot stamping. For processing, the holographic or embossed hot stamping text should be applied first, but no matter whether the holographic or embossed hot stamping is first applied, it is easy to cause slight scratches to the hot stamping part during the processing, which will affect the product quality, and there will be two times in the two processes Process loss, the increase in loss directly leads to a decrease in the product qualification rate. In addition, the hot stamping process needs to perform plate alignment and calibration on the honeycomb plate dedicated to hot stamping. Two times of hot stamping need to be installed and corrected twice. The processing time will be doubled, which is very unfavorable for efficient production

[0004] Although the current technology has also appeared the hot stamping plate and related technology that can complete holographic hot stamping and concave-convex hot stamping in the same process, such as the hot stamping process and hot stamping plate disclosed in patent documents CN101693427A and CN204977805U, but, due to the general holographic hot stamping area and concave-convex The bronzing area is divided far away, mostly above 50mm, so there is a difference in temperature between holographic hot stamping and ordinary hot stamping. If holographic hot stamping and embossed hot stamping are completed in the same process, it is difficult to guarantee the quality of bronzing; at the same time, due to the The temperature and pressure are greater than those required for holographic hot stamping, and the existing holographic hot stamping areas are all extremely flat, so that under high temperature and high pressure, the air in the holographic hot stamping area is difficult to flow from If the air in the holographic hot stamping area cannot be removed instantly, it will easily cause hot stamping mist in the holographic hot stamping area, which will seriously affect the hot stamping quality of the product
