What is stereoscopic printing?

Stereo printing, also called 3D printing, usually refers to stereoscopic raster printing. It uses the principle that simulating the distance between eyes can produce spatial differences. Pixels with different angles and levels are recorded on photosensitive materials, and then three-dimensional effects and even virtual reality are presented on two-dimensional plane images with the help of grating materials. In this way, people can clearly feel the wonderful pleasure of stereoscopic images through eye observation without any tools. Three-dimensional printed matter can't see the three-dimensional effect like a three-dimensional picture on the computer, but after the three-dimensional printed matter is printed, due to the particularity of grating materials, you can see the three-dimensional effect without wearing three-dimensional glasses! Stereo printing originated from the three-dimensional image negative provided by stereo photography. Although the theory of stereo photography has been put forward for more than 100 years, stereo photography has developed in this long time. However, because stereo photo adopted the traditional optical principle in shooting and production, stereo photo has great limitations in its application. In addition, because of the expensive production equipment, complex process operation and high production cost, stereoscopic photography cannot be popularized, and stereoscopic printing is also affected by long process flow and large accumulated errors between processes in the prepress plate-making process, which reduces the picture clarity and affects the printing effect. In the 1980s, the arrival of digitalization promoted the development of stereoscopic printing, and the production technology became more and more perfect and stable. Stereo printing has thus entered a new era. Nevertheless, the rejection rate of stereoscopic printing is as high as 40%, mainly because it is difficult to meet the requirements of screen color separation and amplitude modulation dot accuracy above 300 lines/inch, and it is difficult to overprint screen angles and color printing. 2 1 century, stereo photography entered the digital age, and stereo multi-image synthesis used computer software, computer-to-plate CTP technology and FM dot high-precision printing equipment. The quality system of stereoscopic printing has been guaranteed. This technology is applied to packaging and decoration products, commercial advertisements, science and education cartoons, postcards, New Year cards, anti-counterfeiting labels, trademark labels, mouse stands, various credit cards and so on. Stereo printing will provide us with unlimited business opportunities.
