3D stereoscopic printing is a combination of digital technology and traditional printing technology, which uses a series of stereoscopic images to form a picture, and the surface of the picture is covered with a layer of grating.

To sum up briefly, stereoscopic printing can be divided into four categories:

A, UV printing, (3D pictures are directly printed on pet grating materials,) with strict technological requirements;

B, follow-up paper printing (3D pictures are printed on coated paper, and then the pictures are mounted on the back of grating material with 3D glue). This method is commonly used, and the price is more favorable compared with UV printing;

C, grating plate printing, (plate 3D stereoscopic painting is suitable for making large grating stereoscopic painting from a distance, and the stereoscopic picture is directly printed on ps grating plate with a printer, and the maximum grating size can be 2x3m, which can be spliced);

D, pvc soft adhesive paper mounting printing: it is the application of some 3D printing products used in clothing, shoes and hats, soft trademarks, etc.
