There are two kinds of lamps we usually use, one is the Back light inkjet film and the other is the Positive spray lamp. The light box has the distinction of positive and negative spray. The photo machine has different applications in the positive and negative spray box. In the inkjet printing application of the light box, the printed picture pattern is clear and exquisite, delicate, bright and clear after lighting, good visual, high contrast, rich in layers, high in saturation, high temperature and low temperature resistance, waterproof and UV resistant, no fading .
First, the Positive spray lamp
The positive torch is printed directly on the material of the lamp. The effect of printing is not much different from whether the lamp is turned on. The back is sprayed on the image to use the image to print. There are related options on the print menu. It is installed inside, and the display effect is poor when the light is not turned on, because the internal light is insufficient and the light transmittance of the light is not very good. The lack of illumination makes it difficult to see the printed content of the light. . The positive torch is coated on the front side, and the printed image is colorful and rich in layers. The positive torch can be printed by water-based ink or solvent-based ink. However, after the image is printed, it needs to be coated to improve its color saturation and waterproof function and improve the service life. Moreover, for example, in the application environment of the tea shop, the light box piece can be made completely transparent or semi-transparent if the front part of the light box is used. The full-transmission light box is completely transparent, and it will appear brightly colored only when illuminated by the light, and it will appear dark when there is no light. The translucent light box is translucent, also called too white, and the semi-transparent light box will also show the effect of color photos when there is no light, and it will be more beautiful when illuminated by light.
Second, the Back light inkjet film
The Back light inkjet film is a combination of a base and a coating. The coating is on the back and consists of a special coating and a white opaque layer on it. The white light-shielding layer diffuses the light, and after printing, the ink penetrates through the light-shielding layer to the other side of the coating to present a positive image. The image is printed on the back, and the front of the light box is not damaged, which does not affect the viewing effect of the image. However, it is generally only applicable to the back light box, and the scope of application has great limitations.
From the general price point of view, the back burner lamp is much cheaper than the positive torch. Therefore, many customers often do not need to pay attention to the quality of the back, but many of the commonly used jewellery is a blowtorch. Positive blower film.
