Manufacturing method of broad-width special holographic mold pressing mother matrix

Abstract

The invention provides a manufacturing method of a broad-width special holographic mold pressing mother matrix. The manufacturing method comprises the following steps of: dividing the surface of a base material into a plurality of areas; printing a photo-curing ink layer on the first area of the base material, and performing jointing, light illumination and stripping on the photo-curing ink layer and a holographic nickel plate or holographic film which is provided with a background pattern or special edition pattern; overprinting the photo-curing ink layer on the second area, and performing jointing, light illumination and stripping on an ink layer which is not photo-cured and a holographic nickel plate or holographic film which is provided with a special edition pattern; and metallizing the surface of the base material on which the background pattern and the special edition pattern are copied or only the special edition pattern is copied to obtain a broad-width holographic mold pressing mother matrix consisting of the special edition pattern and the background pattern or a broad-width holographic mold pressing mother matrix consisting of the special edition pattern. By using the manufacturing method provided by the invention, the special edition pattern can be accurately set in the background pattern, and small-area special pattern plates can be assembled into a truly seamless large plate, which is suitable for production, through repeated assembling.

[0002] Patterns (such as figure 1 As shown), it is formed by the hologram recorded by laser one-time photography with white light illumination to reproduce the monochromatic image, and its width is generally more than 780mm×650mm. The technology was very advanced at that time, and only a few people mastered it, so it had a strong anti-counterfeiting effect. However, with the passage of time, ordinary laser holographic image production technology spread rapidly, and its anti-counterfeiting function has gradually lost, but its streamer The appearance of Yicai is still the first choice for high-end packaging

In order to strengthen the anti-counterfeiting ability of ordinary holographic materials, more and more products are turning to use special holographic film as packaging material. A holographic film composed of a special pattern and an ordinary laser holographic pattern (also known as a background pattern); due to the limitation of the production technology of the existing lithography machine, it is impossible to economically produce a large-format and high-resolution holographic master. The usual method of special-purpose holographic molded master is to use a photolithography machine to make a small-format special pattern plate, and then combine the special pattern plates together by splicing, or combine the special image plate with the ordinary laser holographic plate (also called background pattern version) are put together to form a wide-format dedicated holographic molded master

[0003] The special holographic film composed of special pattern, the production of its molded master is generally: through the imposition machine, the personalized pattern on the small-sized special image plate is directly embossed on the transparent substrate, and then the transparent substrate is metallized Afterwards, electroforming is carried out to obtain a wide-width holographic molded master; because the small-sized special image plate will leave a seam when splicing, the existence of these seams will cause discontinuity in the image and text, which will seriously affect the quality of the product

[0004] There are currently two methods for the production of the molded master plate of the special holographic film composed of the special pattern and the background pattern: one is to use the method of manual film stitching, that is, to set the special pattern on the background pattern in advance. The position is hollowed out, the background pattern plate is pasted on the plate roller first, and then the special pattern plate is pasted on the hollowed out place, and all the information of the background plate and the special plate are transferred to the film by heating and pressing, and then the process is carried out by a well-known method in the industry. Silver spray metallization and electroforming to form a wide-width special holographic molded master; the other is the method of using machine imposition, that is, the special pattern plate is first pasted on the die head, and the information on the background pattern plate is first passed through the molding method. Copy it on the PC resin board, and then transfer the information on the special pattern plate to the PC resin board with the background version information one by one by means of flat pressure heat transfer, and then carry out silver spray metallization, electrical Casting to form a wide-format holographic molded master; due to the low efficiency of manual imposition, the position accuracy is not high, and gaps are prone to appear where the special pattern and the background pattern are connected, resulting in neither the special pattern nor the background pattern in the gap , affect the effect of subsequent printing, and also affect its anti-counterfeiting performance; and machine imposition, if the area of ​​the special pattern is large, it is difficult to control its uniformity due to the heat source and pressure, and the quality of the middle and edge of the special pattern is difficult to be consistent , resulting in certain flaws in the transfer pattern
