Problems solved by technology

Due to the small size of the special image plate will leave a seam when splicing, the existence of these seams will cause the discontinuity of the image and text, which seriously affects the quality of the product
[0004] Through the search, no public process technology involving the use of nickel plate imposition was found

Embodiment Construction

[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0024] A laser holographic anti-counterfeiting film nickel plate imposition method is to use the electroforming method to make two special laser holographic image nickel plates with a thickness of 30 μm. The size of the nickel plate image is 10cm×10cm, and enough blank areas are reserved around.

[0025] The steps of imposition method are:

[0026] (1) Cut two laser holographic nickel plates with a thickness of 30 μm, the cutting edge is straight and without burrs, and produce the No. 1 nickel plate 5 with a size of 15cm×15cm, an...

Abstract

The invention relates to a method for imposing a nickel plate of a laser holographic anti-counterfeit film. Two nickel plates with a thickness of 30 μm and a special laser holographic image are produced by electroforming, and the size of the nickel plate image is 10cm×10cm. The invention scientifically interprets the inverse relationship of splicing units, and adopts the reserved distance for splicing and the method of applying photoresist to carry out accurate splicing of nickel plates, and does not waste nickel plates, and all nickel plates can be repeated during the entire splicing process In addition, the electroformed nickel plate is flat, the plate seam is strong and durable, and the imposition seam is less than 0.1mm; there will be no cracking of the plate seam during the molding process, which not only enhances the bonding strength between the daughter board and the daughter board, but also realizes Simple yet precise alignment.

Description

technical field [0001] The invention belongs to the field of packaging printing technology and anti-counterfeiting technology, and relates to a nickel plate imposition process for producing laser holographic anti-counterfeiting materials, in particular to a nickel plate imposition method for laser holographic anti-counterfeiting film. Background technique [0002] Laser holographic images are used as anti-counterfeiting marks due to their difficulty in production and high barriers to entry, and are widely used in packaging, certificates, stamps, coins, etc. At present, the high-efficiency laser holographic image production method is to transfer the texture pattern with a certain shape from the metal master plate to the product to be imprinted by embossing. Therefore, making a metal nickel plate as a metal master plate has become The key to this technical method, and the quality of the imposition technology is the key to the production of metal nickel plates. The mainstream ...
