Problems solved by technology

[0003] However, this one-way perspective sticker has the following disadvantages: 1. After pasting, the one-way perspective sticker has stress, and the edge curls or the inkjet surface shrinks.
2. After the inkjet is punched, the strength of the product is not enough, and the self-adhesive layer is also reduced due to the punching, making the paste not firm
3. The punching part is exposed to the outside for a long time, resulting in hole marks on the glass, which is very dirty and difficult to clean
4. The larger the hole, the lower the accuracy of the picture, and the smaller the hole, the worse the perspective effect

Abstract

The invention relates to a manufacturing method of a unidirectional perspective paste with single-sided printing and picture displayed at both inside and outside. The method comprises the following steps: (1) preparation of a printing super permeable membrane; (2) preparation of a unidirectional perspective paste; and (3) preparation of the unidirectional perspective paste with single-sided printing and picture displayed at both inside and outside. Compared with the prior art, the invention has advantages of improved printing precision, clear picture, improved product strength, no printing surface shrinkage, improved bonding fastness, no warped edge, cleanness and easiness for cleaning.

Description

technical field [0001] The invention relates to a one-way see-through sticker, in particular to a manufacturing method of a one-way see-through sticker with single-side spray-painted internal and external display images. Background technique [0002] The one-way perspective stickers currently on the market, the surface is a white spray-painted film after punching, the reverse side is a gray or black coated self-adhesive layer after punching, and the bottom of the self-adhesive is a coated release paper. The white spray-painted film and the self-adhesive layer evenly punch out small holes arranged in a rectangular array. When in use, spray the picture on the white spray-painted film surface, peel off the coated release paper, and stick it on the transparent glass. This one-way perspective sticker is widely used in advertising and other fields based on the principle of small hole imaging. It is especially suitable for glass, car windows, etc. You can see the spray-painted pic...
