UV makeup method of holographic dedicated plate

Abstract

The invention provides a makeup method of a holographic dedicated mother plate. The makeup method comprises the following steps: 1. designing and making a location film and an exposure film according to mother plate patterns; 2. adding a UV paint A between a transparent substrate and a holographic nickel plate or a holographic film, rolling to uniform, jointing the exposure film, irradiating light, stripping and cleaning; 3. adding a UV paint B between a small-width transparent substrate and a holographic unit nickel plate or a holographic film, repeating the processes after addition of the UV paint A in the step 2; 4.on an operating table successively placing the location film, a transparent large plate (with the surface of the pattern up) and a transparent small plate (with the surface of the pattern down), wherein the transparent large plate and the transparent small plate being in counterpoint jointing; 5. adding the UV paint A below the transparent small plates and then repeating the processes after the addition of the UV paint A in the step 2; 6.obtaining a broad-width holographic transparent large plate; 7. obtaining the broad-width holographic dedicated mother plate through metallization processing on a coating layer surface. The makeup method of the holographic dedicated mother plate has the advantages of high precision and no generation of bubbles and clearances, and the broad-width seamless holographic large plate which is suitable for production is prepared through repeating makeup of holographic dedicated pattern small plates.

Description

technical field [0001] The invention relates to a method for imposing laser holographic special plates, in particular to a method for imposing laser holographic special plates using light curing technology. Background technique [0002] One of the most important processes of molded holographic technology is to make a holographic molded master. In the mass production process of molded holographic products, the holographic molded master is required to have a larger size, that is, a wide holographic molded master. The manufacturing method of the wide-width holographic molding template in the prior art is to directly emboss the holographic pattern on the small-sized holographic molding template onto the plastic sheet through an imposition machine, and then electroform the plastic sheet to obtain a wide-width holographic molding template. The holographic molded master plate is cast to obtain a wide-width holographic molded template. Due to the small size of the special image pla...

Problems solved by technology

[0004]Traditional manual imposition is not only inefficient, but also the location accuracy is not high, and gaps tend to appear where the special pattern and the background pattern connect, resulting in no special There is no background pattern in the plate pattern, which affects the subsequent printing effect and its anti-counterfeiting performance; while machine imposition, if the special plate pattern area is large, it is difficult to control the heat source and pressure uniformly, and the quality of the middle and edge of the special plate pattern is difficult to be consistent. There are certain defects in the special pattern that causes the transfer; the above-mentioned UV imposition method, the bonding process of the UV coating layer and the holographic nickel plate or holographic film is not easy to operate, and it is easy to generate bubbles and voids, which makes the holographic information transfer effect incomplete, and the UV coating layer Positioning printing involves issues such as printing plate making, overprinting accuracy, and cumbersome operations
