Stereoscopic printing originates from the three-dimensional image negatives provided by stereo photography. Although the theory of stereoscopic imaging has been published for more than 100 years, stereo photography has developed to a certain extent in this long period of time. However, due to the traditional optical principle of making and synthesizing stereo photographs, the stereo photo has great limitations in application, plus expensive production equipment, complicated operation technology, high production cost, etc. Stereo photography cannot be promoted and popularized. Therefore, stereo printing is also subject to long process flow in the prepress printing process, and the cumulative error between processes is large, which reduces the sharpness of the image and affects the printing effect.
In the 1980s, due to the advent of digitalization, the development of three-dimensional printing was promoted, and the production technology was becoming more and more perfect and stable. Three-dimensional printing entered a new era. Despite this, the scrap rate of stereo printing is as high as 40%, mainly because the plate color separation and the amplitude adjustment dot precision are difficult to reach 300 lines/inch or more. The cable angle and color printing overprinting are difficult. In the 1970s, China's high-precision four-color offset printing machine The number is limited, it is difficult to meet the technical requirements of three-dimensional printing. Fortunately, in the early 1980s, Beijing Printing College provided us with printing quality assurance. The only one of them was the Heidelberg four-color offset printing press with CPC remote control. , so that the stereoscopic print quality rate reached more than 85%. Establish our confidence in improving quality.
In the 21st century, stereo photography entered the digital age, and the three-dimensional multi-image synthesis uses computer software, computer direct plate making, <CTP> technology, and uses high-precision printing equipment for FM network. The three-dimensional printing quality system has been guaranteed.
At present, the application scope of three-dimensional printing has not been understood by the masses, and it is still impossible to get rid of the concept of "treasures". Therefore, when commissioning a printing house, it is often the case that it is intended to be monopolized. Nowadays, from the perspective of the market economy, it should be considered as far as possible from the perspective of a wider range of uses and users. As soon as possible, the focus will be on long-term and widespread use. The range of three-dimensional printing applications is compelling. In packaging and decoration products, commercial advertising, science and education cartoons, postcards, Chinese New Year, anti-counterfeiting marks, trademark tags, mouse support, all kinds of credit cards. Three-dimensional printing will provide us with unlimited business opportunities.
