AI Technical Summary

Technical Problem

Existing 3D grating lamination technology makes it difficult to achieve local anti-counterfeiting printing on paper, and the uncovered part is easily damaged when the hard grating film is bonded to the paper.

Method used

First, light-colored UV ink and UV high-gloss transparent oil are printed on the paper to form a background, then the logo image is printed and high-temperature transparent hot-melt resin is sprayed to form a transparent spacer layer, and then a microlens array is printed on the spacer layer to present a three-dimensional dynamic pattern using the microlens array.

Benefits of technology

It realizes the partial printing of three-dimensional dynamic anti-counterfeiting patterns on paper, enhances the flexibility and strength of the anti-counterfeiting label, avoids the damage caused by the hard grating film, and presents a three-dimensional dynamic anti-counterfeiting effect.

Abstract

The application discloses a three-dimensional dynamic pattern anti-fake label and a printing method thereof, and relates to the technical field of anti-fake printing. The anti-fake printing method comprises the following steps: printing a layer of light-color UV ink on paper by offset printing, and printing a layer of UV high-light transparent oil on the light-color UV ink to obtain a UV high-light transparent oil layer; printing a dynamic target base pattern on the UV high-light transparent oil layer by UV offset printing to obtain a three-dimensional dynamic pattern base layer; printing mark graphics on the three-dimensional dynamic pattern base layer to form a first anti-fake pattern; spraying high-temperature transparent hot-melt resin on the first anti-fake pattern to form a transparent interval layer; and printing a silk screen microlens array on the transparent interval layer by using transparent UV expansion ink to obtain a second anti-fake pattern with the three-dimensional dynamic pattern.
