Abstract

The invention relates to a method for printing an embossment microstructure with a positioned color register, in particular to a method for the integrated online printing of an embossment type optical microstructure layer which is positioned and nested with an ink color. The method comprises the following steps: taking a microstructure area as a special color for printing; printing a molding ink at a specified position; in the state that the ink area is not completely dried and solidified, attaching and die-casting the ink area in a positioning mode by an embossment microstructure mother set roller on a next printing plate roller so that the ink is embedded in an embossment microstructure groove on a mother set; and solidifying and molding a hinge for drying the ink in a coating area of a printing material and a microstructure image, wherein the embossment shaped microstructure on the mother set roller is completely copied to the ink surface of a printing stock in a mirror image mode, and a copying molding area serves as a color register printed at the specified position and can be connected with front and back printing colors to form a + / -0.15 millimeter printing registration accuracy. The method can achieve the positioned color register with a common printing and the accurate positioning of pattern and ink printing on the mother set.

Description

[technical field]

[0001] The invention relates to a method for positioning and registering an embossed microstructure printing method, in particular to an integrated on-line printing method for embossed optical microstructure layer and ink color positioning and nesting. [Background technique]

[0002] The embossed microstructure can produce color separation and directional deflection of incident light, and can produce high-intensity changeable colors through optical coating and other treatments, lifelike three-dimensional images, hidden information text and micron extremely fine graphics, which cannot be achieved by ordinary ink printing It can be widely used in anti-counterfeit cards, packaging, positioning labels, functional materials and other fields. The substrates can be plastic, paper, glass and other hard and soft plates.

[0003] At present, most of the embossed microstructure replication methods are molded holography, which is pressed and formed on thermoplastic mat...
