Process and device for manufacturing three-dimensional imaging anti-counterfeiting packaging with positioning function

Abstract

The invention relates to the fields of printing, packaging and machinery, in particular discloses a process and a device for manufacturing three-dimensional imaging anti-counterfeiting packaging with a positioning function. The technology comprises the following steps of: (1), printing a printing layer comprising a printing structure and a printing pattern at the specified position below a film through high-precision printing; (2), manufacturing an optical element at the specified position above the film; and (3), positioning and cutting a film finished product. The optical element structure and the printing structure on the three-dimensional imaging anti-counterfeiting packaging produced by adopting the process and device form the packaging having the positioning and anti-counterfeiting functions and presenting the effect of stereoscopic vision in a mutual-interference imaging mode, and the packaging can be used for various products with high added values.

Description

technical field [0001] The invention relates to the technical fields of printing, packaging and machinery, and relates to a manufacturing process and a manufacturing device, in particular to a manufacturing process and device of a high-precision three-dimensional imaging anti-counterfeiting package with a positioning function. Background technique [0002] Due to the limitations of human vision on resolution, existing products with high-precision anti-counterfeiting functions require some form of tools to decode or display anti-counterfeiting features. This kind of second-line anti-counterfeiting means has great requirements and costs for the sales of tobacco companies' best-selling brands in terms of distribution and explanation to consumers, and because all anti-counterfeiting materials, including anti-counterfeiting inks on banknotes, can be purchased in the market or by It is provided by outsourcing manufacturers, so its anti-counterfeiting strength is very limited.

Problems solved by technology

Due to the relationship between production principle and precision, holographic hot stamping has not been able to be presented and produced in the form of printing.

However, regardless of the three-dimensional imaging process used in three-dimensional printing, whether it is the principle of strip imaging, parallax imaging or collision imaging, it is impossible to use thin films to generate three-dimensional images due to the mutual restraint between the thickness of the transparent layer, the number of grating lines, and the printing accuracy. visual effects of
