Second, light box sheet material
1Back spray light box piece
The back spray light box sheet is composed of a sheet base and a coating. The coating is on the back and consists of a special coating and a white light blocking layer on top of it. The white shading layer makes the light diffuse, and the ink penetrates through the shading layer to the other side of the coating after printing, presenting a positive image. The image is painted on the back, and the front of the light box piece will not be harmed, and the viewing effect of the image will not be affected.
2Positive spray light box piece
Positive spray light box sheet is front coating, printing images colorful, rich layers. The positive spray light box sheet can be printed with water-based ink or solvent-based ink, but it needs to be coated after the image printing is completed to improve its color saturation and waterproof function and improve its service life.
Three, light box sheet production method
①Remove the back film: Evenly remove the film from the back of the color photo.
②Sanding fibers: Smooth the wool fibers on the paper base on the back of the photo.
③Paper enhancement base: The anti-reflection material such as resin, varnish, oil or wax is evenly applied to the paper base of the photo, and the transparency of the photo increases after a few hours.
④Speed protection: Slightly dry the anti-reflection material on the back of the enhanced photo and add a protective layer to it. Such as plastic film, transparent varnish, etc.
The above is about the actual needs of different users, and the positive spray light box sheet and the back spray light box sheet are determined, hoping to help friends who mainly make light box sheets!
