Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and the embodiments given in the accompanying drawings. The production technique of the present invention is easy to implement for those skilled in the art.

[0018] 1. The printing material is unwound through the deviation correction device and tension control, and first enters the ordinary ink printing unit, performs at least one single-color ordinary printing and obtains detectable tracking lines, cursors (or the edge of the first set of color images), see figure 1 1 place and figure 2 (A).

[0019] 2. Control the electronic axis 5 or floating roller 3 through photoelectric detection and PLC calculation to accurately apply the transfer printing ink to the required color register position through the gravure roller 6, and keep its viscosity without curing, see figure 2 (B).

[0020] 3. Through photoelectric detection and PLC central calculation, the electronic axis...

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...
