Embodiment 1

[0020] refer to Figure 1~2 , a resin plate for optically variable anti-counterfeiting ink offset printing of the present embodiment, a resin plate for optically variable anti-counterfeiting ink offset printing, comprising a metal base 1, an adhesive layer 2, a resin layer 3, a printed graphic layer 5 and a balance bar 4. The resin layer 3 is attached to the outer surface of the metal-based substrate 1 through the adhesive layer 2, the printed graphic layer 5, the balance bar 4 and the resin layer 3 are integrally formed, and the printed graphic layer 5 and the balance bar 4 protrude The outer surface of the resin layer 3; the balance bar 4 is arranged at intervals on both sides of the printed graphic layer 5, and the position relative to the metal base 1 corresponds to the blank part 71 of the required printed graphic.

[0021] The height of the balance bar 4 protruding from the outer surface of the resin layer 3 is consistent with the height of the required printed graphics,...

Embodiment 2

[0028] Compared with Example 1, the resin plate for optically variable anti-counterfeiting ink offset printing of this example has the following differences:

[0029] The height of the balance bar 4 protruding from the outer surface of the resin layer 3 is 0.8 mm.

[0030] The area of ​​the printed graphic layer 5 is 1 / 10 of the area of ​​the resin layer 3 .

[0031] The metal base 1 is an aluminum base with a thickness of 0.20mm.

[0032] The hardness of the resin layer 3 is 75 degrees Shore hardness.

[0033] The aluminum content in the aluminum base is 99.2%, iron accounts for 0.5%, silicon accounts for 0.25%, copper accounts for 0.01%, and titanium accounts for 0.04%.

[0034] The use method and working principle of a resin plate for optically variable anti-counterfeiting ink offset printing of the present invention are as follows: the resin plate is sleeved on the plate roller 6, and the resin plate is in contact with the anilox roll, and the printing graphic layer 5 of...

Abstract

A resin plate for optical variability anti-fake ink offset printing comprises a metal matrix base body, a bonding layer, a resin layer, a printing image-text layer and balance strips. The resin layer is attached to the outer surface of the metal matrix base body through the bonding layer. The printing image-text layer, the balance strips and the resin layer are integrally formed, and the printing image-text layer and the balance strips protrude out of the outer surface of the resin layer. The balance strips are arranged on the two sides of the printing image-text layer at intervals, and the positions, opposite to the metal matrix base body, of the balance strips correspond to blank parts of an image and text needing to be printed. The resin plate for optical variability anti-fake ink offset printing is simple in structure and convenient to use, uniform stress between the resin plate and a printing stock is facilitated, and printing is stable. The press run is high, and compared with a traditional resin plate, the amount of paper capable of being printed by the resin plate is 1.5 times of the amount of paper printed by the traditional resin plate. The service life of the resin plate is long.

Description

technical field [0001] The invention relates to a resin plate for printing, in particular to a resin plate for optically variable anti-counterfeiting ink offset printing. Background technique [0002] Offset printing is a kind of lithographic printing. By means of rubber (metal-based resin plate and UV glazing blanket), the graphics on the printing plate are transferred to the printing material. These two glazing media can ensure that the printed matter Different needs of glazing. However, metal-based resin plates are used in existing offset printing equipment, and the substrate (paper) is easily deformed and rubs against the blank part of the resin plate, causing the pattern on the substrate (paper) to be scratched. [0003] CN 104723716 A discloses a metal-based resin plate for laser direct plate-making, which contains an oxidized and electrolytically treated metal-based support, a bonding layer that absorbs UV light refraction and scattering, a photosensitive elastomer l...
