Problems solved by technology

[0002] Generally, the direct imposition of the laser nickel plate is made by applying conductive adhesive to the imposition seam, or by welding, but there are problems of thick imposition seam or poor flatness of the imposition seam. As a result, the seams of the remade master plate are more obvious, which affects the quality of the produced laser anti-counterfeiting materials

Embodiment Construction

[0029] Please refer to Fig. 1 as shown in the schematic diagram of imposition structure of the present invention, a kind of imposition process of laser nickel plate, it is characterized in that comprising the following steps:

[0030] The first step: cutting the laser nickel plate with a thickness of 20-30 μm, and the cutting edge is straight and burr-free;

[0031] Pre-bonding: face up two laser nickel plates 1 and 2 with the same thickness, splice their straight and burr-free cutting edges relative to each other, and temporarily bond them together with adhesive tape;

[0032] Step 2: Put a magnetic rubber plate on a flat table, put a layer of copy paper on the magnetic rubber plate, turn the two pre-bonded laser nickel plates 1 and 2 over, and cover the magnetic rubber plate with the front facing down On the copy paper, splice the straight and burr-free cutting sides together, and the 8 seams are closely attached to each other;

[0033] Correction: Grind, smooth, and clean ...

Abstract

The invention relates to a plate splicing process of laser nickel plates, which comprises the following steps of: cutting the laser nickel plates with the thickness of 20-30mu m, wherein cut edges are flat and straight and have no burr; placing the two laser nickel plates with consistent thickness and downwards front surfaces on a magnetic rubber plate, oppositely splicing the respective cut edges which are flat and straight and have no burr, and mutually pressing a joint; bonding an adhesive tape at the joint of the back surfaces of the two laser nickel plates, and then bonding a double-faced adhesive tape with the width smaller than that of the adhesive tape at the middle part of the adhesive tape; pasting an reinforced nickel plate with the width larger than the adhesive tape to the double-faced adhesive tape, and wrapping the whole adhesive tape and the double-sided adhesive tape; and respectively bonding and fixing the reinforced nickel plate and the laser nickel plates at the left side and the right side of the reinforced nickel plate through the adhesive tape. The invention has the advantages that compared with the prior art, the invention has the key that plate cutting and plate splicing processes are different, the whole process is concise and novel, has strong operability, thinner plate splicing joint (which can be smaller than 0.1mm) and better evenness, can greatly improve the plate splicing quality and is applicable to the direct plate splicing of the laser nickel plates.

Description

technical field [0001] The invention relates to the technical field of packaging and printing, in particular to an imposition process of a laser nickel plate for producing laser anti-counterfeiting materials. Background technique [0002] Generally, the direct imposition of the laser nickel plate is made by applying conductive adhesive to the imposition seam, or by welding, but there are problems of thick imposition seam or poor flatness of the imposition seam. As a result, the patchwork of the master plate that has been reproduced is more obvious, which affects the quality of the laser anti-counterfeiting materials produced. Contents of the invention [0003] The problem to be solved by the present invention is to provide an imposition process of the laser nickel plate, so that the imposition seam of the laser nickel plate is less than 0.1mm, and the flatness of the imposition seam is better. [0004] The technical scheme adopted by the present invention to solve the abo...
