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 laser holography anti-fake film nickel plate slicing method which comprises a step of manufacturing two special laser holography image nickel plates by using an electric casting method, wherein the thickness of each special laser holography image nickel plate is 30 microns, and the size of a nickel plate image is 10cm and 10cm in wide and length. The method scientifically explains the negative and positive relationship of a slicing unit, the nickel plates are accurately spliced in modes that splicing distance is preserved and photoresist is smeared, the nickel plates are not wasted and can be repeatedly used in the whole splicing process, the electric-plated nickel plates are smooth, and the plate seam is solid and durable, and is smaller than 0.1mm; the phenomenon that the slicing seams are fractured is avoided in the mold pressing process, and the binding strength of sub-plates is improved, and simple and precise alignment is achieved.

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 ...
