Perspective film

Abstract

The invention discloses a perspective film, comprising a transparent film and backing paper, wherein a color-development printing layer is printed on the transparent film and is composed of color-development printing bodies and light transmitting areas, wherein the color-development printing bodies and the light transmitting areas are staggered; and the transparent film is laminated on the backing paper. According to the invention, because the color-development printing layer is directly printed on the transparent film, a pictured sprayed and drawn on the transparent is very clear by means of the color-development printing layer; in addition, because the color-development printing layer is composed of the staggered color-development printing bodies and light transmitting areas, the requirements of a light transmitting effect and a perspective effect can be met under the condition of guaranteeing the clear display of the sprayed picture; because the transparent film per se is not punched, the transparent film at the light transmitting areas can be used for blotter and coloring, the precision of the picture is high, the definition of the front face of the picture is greatly increased compared with that of the traditional unidirectional perspective patch, and the picture can be displayed from a back face and is not influenced by light intensity at two sides of a transparent plate; and the color-development printing layer is arranged on the transparent film in a printing manner, so that the production efficiency is greatly increased, the manufacture is more convenient and the production cost is low.

Description

technical field [0001] The invention relates to a see-through film, in particular to a see-through film widely used in the fields of advertising, decoration and the like, and especially suitable for pasting on transparent plates such as glass and car windows. Background technique [0002] There is a one-way perspective sticker in the prior art, which includes a layer of inkjet film (generally PVC film), and a self-adhesive layer (usually called a pressure-sensitive adhesive layer) on the reverse side of the inkjet-paintable surface of the inkjet film. Sensitive glue, for the sake of understanding, hereinafter referred to as self-adhesive), paste the backing paper (coated paper) on the self-adhesive layer, and evenly distribute several small holes on the inkjet film and self-adhesive layer, each Small holes all run through the inkjet film and the self-adhesive layer. The production process is to punch the inkjet film pasted with the backing paper through a punching machine t...

AI Technical Summary

Problems solved by technology

[0003] However, this one-way perspective sticker has the following disadvantages: 1. The film for inkjet printing is slow to punch holes (only about one meter per minute), which leads to low production efficiency; 2. A lot of garbage will be generated during the production process (Garbage caused by punching), polluting the environment; 3. The bottom paper has been scrapped after being punched, and must be replaced with a new non-punched bottom paper, resulting in great waste and high production costs; 4. The noise of the machine is very loud when punching holes, which is likely to cause noise pollution; 5. Since the film for inkjet printing is perforated, from the front, the inkjet painting picture cannot be displayed at the hole, so the accuracy is not high; 6. The picture cannot be seen from the reverse side , so the image can only be displayed in one direction; 7. When in use, if the side of the inkjet printing film with a picture is weak in light, but the side without the picture is strong in light, the picture cannot be seen clearly (especially at night); 8. 1. Due to the perforation of the inkjet film, its strength is low, and the edges are easy to warp after pasting, and the adhesion is not firm; 9. It is difficult to tear the old picture when changing the picture, and it is easy to break when it is torn, and it is inconvenient to replace; 10. It is easy to accumulate dust in the hole and pollute the screen, and after tearing, it is easy to leave hole marks on the bonding place
