Stereoscopic printing originated from the three-dimensional image negatives provided by stereo photography. Although the stereographic imaging theory has been proposed more than one hundred years ago, stereo photography has developed to a certain degree during this long period of time. However, due to the use of traditional optical principles in the production and synthesis of stereoscopic photographs for photographing and production, there are many limitations in the application of stereoscopic photographs, as well as the expensive production equipment, complicated process technology operations, and high production costs. The three-dimensional photography cannot be promoted and popularized. Therefore, the three-dimensional printing is also subject to a long process flow in the pre-printing process, and the cumulative error between the processes is large, which reduces the definition of the screen and affects the printing effect.

In the 1980s, due to the arrival of digitalization, the development of three-dimensional printing was promoted, and the production technology became more and more perfect and stable. Therefore, three-dimensional printing entered a new era. In spite of this, the three-dimensional printing waste rate is as high as 40%, mainly due to the difficulties of plate separation and amplitude modulation, and the difficulty in achieving 300 lines/inch or more. The screen angle and color printing are difficult to print. In the 1970s, China's high-precision four-color offset printing press With a limited number of products, it is difficult to meet the technical requirements for three-dimensional printing. Fortunately, in the early 1980s, the Beijing Institute of Graphic Arts provided us with print quality assurance, using them to teach an internship factory that was the only one Heidelberg four-color four-color offset printing press with CPC remote control. , so that the stereo print genuine rate reached 85% or more. Build our confidence in improving quality.

In the 21st century, three-dimensional photography entered the digital era. The three-dimensional images were synthesized using computer software and were directly processed by computer. Technology, and the use of high-precision printing equipment network FM. Three-dimensional printing quality system has been guaranteed.

At present, the scope of three-dimensional printing applications has not yet been understood by the general public, and it is still impossible to get rid of this concept of “treasures.” Therefore, when a printer is asked to print, there is often a case where it is intended to be monopolized. Today, from the perspective of the market economy, it should be considered as far as possible from a wider range of uses and users, focusing on long-term and extensive use as soon as possible, and the application of three-dimensional printing is attracting attention. In packaging and decoration products, commercial advertising, science and education cartoons, postcards, New Year's cards, anti-counterfeit marks, trademark tag, mouse care, all kinds of credit cards. Three-dimensional printing will provide us with unlimited business opportunities.
