A kind of holographic positioning cold stamping printing method

Abstract

The invention discloses a holographic positioning cold stamping printing method, comprising step 1, using a cold stamping film containing a holographic pattern to perform cold stamping printing on white cardboard through a cold stamping printing machine, to obtain a cold stamping plate; and step 2, drying and peeling the first plate After filming, offset printing is carried out on an offset printing machine to obtain a finished plate. A holographic positioning cold-foil printing method of the present invention skillfully adopts the cold-foil film containing the holographic pattern and applies it to the printing process of the holographic pattern of the packaging box, which can not only greatly improve the printing quality, but also realize the The process of hot stamping and offset printing of holographic patterns can be completed in two steps at one time, and better quality packaging box printing products can be directly obtained. It changes the high temperature and equipment requirements required for high temperature hot stamping, reduces the printing process cost, improves the printing efficiency, and also reduces the environmental pollution of materials and manufacturing processes.

Description

technical field [0001] The invention relates to a printing method, in particular to a holographic positioning cold stamping printing method with simplified procedures and high printing quality. Background technique [0002] Packaging box is a kind of container used for packaging goods. In order to make the appearance of goods more beautiful and increase consumers' desire to buy, there are endless styles of packaging boxes, and the quality requirements are getting higher and higher. Especially in the tobacco industry, most of the middle and high-end cigarette boxes are printed on gold, silver or laser cardboard, and then the holographic pattern is hot-stamped on the printing surface to obtain a dazzling appearance effect, which is particularly important as a packaging material for tobacco products of high-end. Hot stamping laser holographic patterns on high-grade cardboard, the existing process includes at least two processes of offset printing and hot stamping, the color pr...

AI Technical Summary

Problems solved by technology

However, the cost of gold, silver, and laser cardboard is relatively high, and it needs aluminized film transfer and molding to achieve the laser effect, resulting in defects such as environmental protection and high cost.

And because the hot stamping and ink printing temperatures of holograms are different, they need to be completed by two sets of equipment respectively. Not only is the process complicated, but the accuracy and quality of hot stamping cannot meet the quality requirements of high-end products, and the cost is high, making it impossible to make the existing Products are highly competitive in the market
