Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a colorful scrapeable coating printing layer structure. Background Art

[0002] There are currently two methods for making lottery tickets. The first is to apply a layer of silicone oil on the surface of the substrate (paper). The second lottery ticket uses a peel-off number. The structural shape is first printed with a pattern and the winning number or mark using offset printing, and then bonded, compounded, and molded.

[0003] Existing scratch-off tickets are usually silver-gray or black-gray, and are usually made by silk-screen printing or hot stamping. There is no color scratch-off ticket, which lacks beauty and fun for its application products. Therefore, a color scratch-off coating printing layer structure is proposed. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2As shown, the utility model provides a technical solution: a color scrapeable coating printing layer structure, including a film layer 1, a removable resin layer 2, a covering layer 3 and a printing layer 4, the film layer 1 is a PET film, and a removable resin layer 2 with a peeling force of 0.002-0.004 N / m is coated on the film layer 1. Such a peeling force not only ensures that the coating will not be easily scratched during the production process, but also ensures the scraping property of the finished product under appropriate force. The surface tension of this layer of resin wax should be controlled at 32-34 dynes to ensure that the subsequent printed covering layer has good bonding force. The covering layer 3 is arranged on the film layer 1 coated with the removable resin layer 2, and the covering layer 3 is flexographically printed. , offset printing or digital printing, print a covering layer 3 of ink with strong hiding power on the area to be scraped off on the film coated with the transferable resin layer, the thickness of the covering layer 3 is 1-2 microns, and the printing layer 4 is arranged above the covering layer 3, and the printing layer 4 is overprinted with the required color graphics on the ink printed with strong hiding power by flexographic printing, offset printing or digital printing, and the thickness of the printing layer 4 is 1-2 microns. The utility model makes the usual printing ink scrapeable by printing, which can replace the existing coating and has both decorative and interesting properties. It also combines the color printing process with the scrapeable coating to increase the anti-counterfeiting and decorative properties of the product, replace the silk-screen scraping ink method, and reduce costs.

[0021] The removable resin layer 2 in the device is preferably polyethylene wax, which is produced by coating a layer of removable resin on a PET film using a coating machine.

[0022] In addition, the covering layer 3 in the device is made of ink, and white ink or black ink is preferred because white ink and black ink have strong covering properties. Of course, if the image to be covered is colored, it is best to use colored ink similar to the image as the covering ink, which will interfere with the image to be covered, that is, it will be deceptive to the eyes, making it difficult for people to find the covered image.

[0023] The overall thickness of the removable resin layer 2, the covering layer 3 and the printing layer 4 in the device is 3-5 microns. Such a structure with a certain thickness is more suitable for scraping. If it is too thick, the cost will be high, and if it is too thin, it will be difficult to scrape.

[0024] Working principle: The utility model can make the usual printing ink scrape off by printing, which can replace the existing coating, and has both decorative and interesting properties. It combines the color printing process with the scrape-off coating to increase the anti-counterfeiting and decorative properties of the product, replace the silk-screen scraping ink method, and reduce costs.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
