Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0019] A kind of manufacture method of anti-counterfeit photoresist film belt provided by the invention comprises the following steps:

[0020] S1. Use professional drawing software on the computer to draw design drawings.

[0021] S2. Select a diffractive lithography machine, and set the number of alignments of the lithography machine to 2200-2600. Preferably, the inventor has found that the anti-counterfeiting effect is the best when the number of alignments is 2400-2500 through multiple tests. Then the design drawing is photoetched on the glass plate, the photoresisted surface of the glass plate is flat, and a layer of photoresist is evenly coated on it.

[0022] S3. Spraying silver on the photoetched glass plate, and then electroforming a replica to obtain a metal nickel ...

Abstract

The embodiment of the invention discloses a method for manufacturing an anti-counterfeiting photoetching film tape, which comprises the following steps: S1, drawing a design drawing; S2, setting the number of alignment lines of the photoetching machine to be 2200-2600, and photoetching a design drawing on a glass plate; S3, spraying silver on the glass plate, electroforming and copying to obtain ametal nickel plate; S4, recopying the metal nickel plate to obtain a working plate unit, and splicing a plurality of working plate units to obtain a working plate; and S5, copying the pattern mirrorimage on the working plate onto the thin film material through high temperature and high pressure to obtain the anti-counterfeiting photoetching film tape. Compared with the prior art, the manufacturing method of the anti-counterfeiting photoetching film tape has the following beneficial effects that as the surface of the photoetching film tape is lost by about 20 percent in each copying, the manufacturing method of the anti-counterfeiting photoetching film tape improves the alignment number of the photoetching machine during photoetching, so that the manufactured original photoetching film strip reaches the imaging limit; and if the original photoetching film strip is copied again to forge the photoetching film strip, the pattern on the surface part of the original photoetching film stripis lost, and the function of preventing the photoetching film from being forged is realized.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeit photoresist tapes, in particular to a method for manufacturing an anti-counterfeit photoresist film tape. Background technique [0002] Using holographic printing technology to make anti-counterfeiting marks and attaching them to the surface of packaging is currently the most popular anti-counterfeiting method. Commonly used is laser rainbow embossed hologram anti-counterfeiting technology, which is a kind of visible graphic information produced on products by applying laser rainbow hologram plate making technology and mold embossing replication technology. The rainbow holographic image is a rainbow holographic photo made of a general holographic image as a shooting object and processed by a series of procedures. For example, if the photosensitive sheet of photoresist is used to replace the hologram taken by ordinary photos, after exposure treatment, a relief-type phase hologram is obtai...
