Description

A method of making dynamic grain effect printed matter

technical field

The invention belongs to the technical field of printing, and in particular relates to a method for making printed matter with dynamic texture effects.

Background technique

With the anti-counterfeiting upgrade of printed packaging products, the requirements for anti-counterfeiting of paper packaging products are getting higher and higher. At present, the four major printing technologies used by printing companies, gravure printing, offset printing, flexo printing, and silk printing, cannot produce paper crafts with "three-dimensional dynamic texture" effects on paper packaging products. The technology of dynamic texture can be easily imitated by another printing company, so the anti-counterfeiting technology of paper packaging products is reduced.

At present, the method for printing companies to produce three-dimensional dynamic lines is to make anodized aluminum (bronzing film) or positioning paper through holographic lithography. Technology is not mastered by printing companies.

The current automatic screen printing machine does not have a three-dimensional dynamic texture forming device, which is a design defect of the previous screen printing machine (the defect is mainly because the previous printing technology cannot produce paper packaging products with three-dimensional dynamic texture effects, all The screen printing machine manufacturer does not have the production and production of the three-dimensional dynamic texture forming device), and the forming device needs to be designed and installed in alignment according to the pattern position on the screen plate, and the forming unit installed in the alignment screen plate can Better meet the overprint accuracy, so that when the paper packaging products are printed multiple times on the screen printing machine and the printing process increases, the overprint fluctuation of the printed matter is small, the production waste is low, and the production efficiency of the printing enterprise is greatly improved, so that the three-dimensional dynamic lines The forming unit implements applications on printing presses and in the printing field.

At present, the anti-counterfeiting technology of three-dimensional dynamic texture effect used by printing companies is made on anodized aluminum or positioning paper by holographic lithography technology. It is not strong, and does not have any printing technology and color reproduction effect.

The three-dimensional dynamic texture effect anodized aluminum or positioning paper technology produced by holographic lithography has been used for many years. The anti-counterfeiting performance of the three-dimensional dynamic texture paper packaging produced by this kind of paper packaging is greatly reduced (why it is reduced: because of the holographic lithography production technology. Enterprises can make it, and it is easy to be imitated and plagiarized. However, the technology of three-dimensional dynamic lines produced by holographic lithography is not in the hands of printing companies, which is not conducive to the long-term development of printing companies.), resulting in holographic lithography The anti-counterfeiting and visual impact distance of the three-dimensional dynamic texture produced by the technology is getting lower and lower, which can no longer meet the anti-counterfeiting requirements of printing and packaging.
