Equipment for manufacturing multilayer gradual change and light change effect and use method thereof

Abstract

The invention relates to equipment for manufacturing a multilayer gradual change and light change effect. The equipment comprises a printing stock plane magnetic table arranged in a silk screen machine and a UV drying tunnel, a plane magnet is arranged in the printing stock plane magnetic table, a detonation lamp and a UV lamp are sequentially arranged on the UV drying tunnel, and the detonation lamp is an ultraviolet lamp. The method using the equipment comprises the following steps of 1) aligning a printing product; 2) ink mixing and inking; 3) loading a plate by the silk screen machine; 4) impressing to manufacture a multi-layer gradual change effect; and 5) manufacturing the optical variability effect. The printing stock plane magnetic table is installed on an existing silk screen machine, then prepared magnetic fluorescent ink is printed on the printing product through a silk screen plate, the gradient printing effect is formed through a magnetic field, an optically variable fluorescent pigment layer in the ink is excited through the UV drying tunnel, the ink is cured, the printing technological process is effectively shortened, the printing pattern manufacturing effect with the multi-layer gradual change and light change effect is obtained at a time, and the technical efficiency of the silk-screen printing technology is greatly improved; and the gradual change and light change effects on the pattern have the characteristic of bright color.

Description

technical field [0001] The invention belongs to the technical field of packaging and printing anti-counterfeiting, and in particular relates to a device for producing multi-layer gradient and optical change effects and a method for using the same. Background technique [0002] At present, the method and process of printing gradients are to fill in multiple colors when making pre-press files, and use the size of "dots" to print the depth of the color gradient transition. To achieve anti-counterfeiting printed products with multi-layer gradient and light-changing effects, the gradient prints can only be printed with dots (the first offset printing), and the second screen printing light-changing ink covers the first printed pattern. The printing process is relatively long, and the method is complicated, and the gradient and light change effects are single. This technology is a common technology in this field. In actual production, there has always been a secondary overlay print...

AI Technical Summary

Problems solved by technology

However, the printed color block can only present a pair of colors, such as: red-green, green-blue, gold-silver or colorless to colored, etc.

The light-changing effect is relatively simple, and the light-changing effect can only show two reversed colors. It is easy to be copied into the same fake and shoddy printed matter, and the anti-counterfeiting performance is very weak.
