Embodiment
[0021]A production process for photoetching glass to replicate film images, including the following steps:
[0022]S1. Prepare liquid medicine, add sodium hydroxide into purified water in proportion to make sodium hydroxide solution for later use;
[0023]S2 Place the front of the photo-engraved glass pattern on the plate making table;
[0024]S3. Drop UV varnish into the front end of the photoetching glass;
[0025]S4. Paste the coated surface of the film onto the front side of the lithographic glass plate;
[0026]S5. Use UV ultraviolet lamp to irradiate film and photo-engraved glass plate;
[0027]S6. Put the irradiated film and the lithographic glass plate into the solution prepared in step S1 and soak;
[0028]S7. After the pattern on the lithographic glass plate is completely copied to the film, take out the film.
[0029]In one of the embodiments, in step S1, 30 grams of sodium hydroxide per 1000 milliliters of purified water is used to prepare a liquid medicine.
[0030]In another embodiment, in step ...

The invention discloses a production technology of a photoetching glass duplicating film image. The technology comprises the steps that S1, a medicinal solution is prepared, wherein sodium hydroxide is added to purified water according to proportion to prepare a sodium hydroxide solution for use; S2, the front face of a photoetching collotype pattern is placed on a platemaking platform; S3, UV gloss oil is added to the front end of the photoetching glass dropwisely; S4, the surface containing a coating of the film adheres to the front face of the photoetching collotype; S5, the film and the photoetching collotype are irradiated by using a UV light; S6, the radiated film and photoetching collotype are placed into a solution prepared in S1 to be soaked; S7, the film is taken out after the pattern on the photoetching collotype is completely duplicated to the film. The technology has the advantages that the photoetching glass is transferred by duplicating image through UV glue, the properties of a UV photoetching glue material are changed to duplicating the photoetching collotype pattern to the surface of the film after photoetching collotype technology is completed, a traditional silver plating technology can be replaced, and the technology is more advanced and convenient.
Description
Technical field[0001]The invention relates to the technical field of holographic anti-counterfeiting plate making, in particular to a production process for photoetching glass to replicate film images.Background technique[0002]The holographic image production process exposed by the traditional lithographic glass plate mainly adopts electroforming silver plating technology. The holographic image on the surface of the lithographic glass sheet is plated with a layer of silver nitrate to cause a chemical reaction and put it into the electroforming tank Production of metallic nickel plates. The above-mentioned production process has a long production cycle and high cost.Summary of the invention[0003]In order to solve the problems in the prior art, the present invention provides a production process for copying film images on photolithographic glass. The production process transfers the photolithographic glass through the UV adhesive replication pattern, and by changing the properties of ...
