The modern printing technology began with John Gutenberg's design of the first complete printing system. It has been more than 500 years old. During this period, three changes can be called epoch-making technological advances.
The first change began in the middle of the eighteenth century. Due to the use of photolithography technology, the exposed plates formed different shades of change to carry thin inks of different thicknesses to achieve a continuous change of tone similar to that of photo effects. Image printing. This kind of printing effect greatly promoted the prosperity of the advertising industry at that time and gave birth to periodical media, which played an important role in promoting the development of science and technology and commerce.
The second change started in the early 20th century. With the help of the development of optics and chemistry technology, the photographic separation technology created a color print production process, which enabled the printing and copying of full-color images; computer technology and laser technology Years have made electrical extensions, so the printing industry can apply analog circuits and subsequent digital circuits to control color separations.
The third change is the research and application of the high-fidelity color printing technology that began at the end of the 20th century. It completely broke through the limitations of the conventional four-color printing gamut, and brought the printing color effect closer to the visual effect of natural color spectrum. The popularity of high-speed large-capacity computers and colorimetric theoretical research and technology applications.
High-fidelity color printing technology is the research content that emerged in the mid-1990s. Some internationally renowned companies, such as HEIDELBERG, AGFA, DUPONT, PANTONE, etc., as well as China's Peking Founder Group, have published their own high-fidelity printing samples since 1995.
The use of high-fidelity color printing technology as a production specification means that the color space for printing and copying colors is based on the visual effects of natural color spectrum. The application of innovative color separation technology can greatly exceed the traditional four-color printing color space. Therefore, in the field of printing, the highest color expression is truly achieved. Due to the birth of CTP technology, high-definition printing effects can be realized under the condition that the printing equipment and materials are basically unchanged, and the continuity of sharpness and tone of the printed matter is greatly improved, and the visual clarity and exquisiteness of the printed image are also improved. Have been greatly improved.
The research and application of high-fidelity color printing technology is a technological revolution in the field of printing, which has greatly promoted the quality of printed matter. In the printing industry, it also triggered a series of changes in personnel concepts, application technology standards, and quality standards. As a result, the overall strength of printing companies has leapt to a new level.
If Gutenberg had designed the first complete printing system before—movable typesetting and various basic forms of printing technology—it was called the first generation of printing technology, which featured the ability to print only single-colored text and lines. In this sense, a long time after the start of modern printing technology, it was still in the first generation of printing technology.
In the middle of the eighteenth century, photographic technology was introduced into the process of printing platemaking. The continuity of the tone of the printed image became the main content of technological progress, and the printing technology represented by it was the second generation.
In the early 20th century, the photographic color separation technology entered the printing platemaking process, and the color separation and screening technology necessary for printing full-color images, and the printing technology represented by it was the third generation, and the modern printing period began. At the end of the 20th century, color separation technology has undergone a revolutionary change. Hi-fidelity color printing technology has begun to enter printing production applications, and high-definition screening technologies and equipment have also become functional in printing companies. With the realization of high-definition and high-fidelity effects for printed copy images, the printing industry began its fourth-generation printing technology era.
Progress in printing technology has not stopped for a moment. The new functions and new quality of printed matter will enable print users and printing companies to obtain more economic and social benefits. In today's fierce market competition, users and service providers achieve a win-win situation is the benign market model.
