The development of traditional printing to digital printing

History of public view printing:

Printing is one of the four great inventions of the working people in ancient China. Block printing was invented in the Tang Dynasty and was widely used in the middle and late Tang Dynasty. Bi Sheng invented movable type printing in Renzong of Song Dynasty, marking the birth of movable type printing. He was the world's first inventor, marking the birth of movable type printing about 400 years before Johannes Gutenberg's lead type printing. Printing is the forerunner of modern human civilization, which has created conditions for the wide dissemination and exchange of knowledge. The following is a development process of printing technology.

History of printing

Types and characteristics of traditional printing:

In fact, the first four stages of printing belong to the traditional way of printing. Traditional Printing methods include Relief Printing (Relief Printing), Intaglio printing (Intaglio Printing), Stencil printing (Stencil Printing) and Planography, which require plate making and stereotyping.

Traditional printing has been inherited for thousands of years, and the technology has been quite mature. Can be very good to achieve high-speed printing, bearing the advantages of low mass printing cost. The disadvantage is that: the need for a complete set of plate making equipment, the need for skilled plate making technical workers, plate making and printing are easy to make mistakes because they can not be well matched, especially the color separation and color correction process, and it takes a long time to change. In the past, traditional printing could still meet people's needs.

The inevitability of digital printing trends:

However, when we enter the 4G/5G era, the rapid development of network technology has broken the traditional rules, eliminated the spatial limitations of people, and the timeliness of human access to information has been unprecedented improved, so anyone can speak for themselves, express themselves and show themselves. Since then, human beings have entered the era of information explosion. People began to slowly form their own values, began to pursue individuation, differentiation, novelty, traditional printing has been unable to meet the needs of contemporary people. In this context, digital printing arises. Because it has no plate making cost, it can be directly output by computer, the diversity of printing materials is flexible and changeable, and it can be printed immediately, without time and space restrictions, which conforms to the diversified needs of The Times. Since 2002, the growth rate of digital printing has greatly exceeded the growth rate of other traditional printing, and the growth rate of more than 10% per year. Therefore, the digital printing industry will lead the entire printing industry. This phenomenon is similar to the use of traditional and digital cameras.

Application areas of digital printing:

Digital printers can print pictures on irregular surfaces, and can print cylindrical objects. Product scope: photo studio, wedding photo studio, scenic spots, hospitals, schools, etc. Industrial application: For plastics, electronics, hardware, plexiglass and other industries sample proofing and product mass production has played a fast sample, processing costs are reduced exponentially. Personalized printing, such as boutiques, mobile phone decoration stores, personalized gift shops; On-site production at tourist attractions or market areas; All kinds of traditional printing template production; Digital image production; Clothing sample proofing or color printing of personalized patterns; Color printing of leather goods; Color printing of laptop shell and tablet appearance; Decoration tile or ceiling color printing, etc.

Digital printing machine:

In 1993, the world's first digital color printing press named Indigo was introduced. Now, a variety of digital printing press brands are also increasing. At present, the technology is relatively good, and the digital printing brands widely used in the world are: HP Indigo, Landa Nano Digital, Gaobo RotaJET, Fujifilm JetPress, Konica Minolta, Heidelberg Linoprint and so on.

Coating solution in digital printing:

Digital printing has made great breakthroughs, in addition to the continuous improvement of the performance of printing machines, the pre-press and post-press supporting measures of printing are also important. Such as printing substrate paper, film coating liquid.

The coating liquid is mainly used for paper and film pre-press surface treatment to prevent ink loss of the substrate during printing and to achieve the purpose of enhancing ink adhesion. A good coating solution will make the print output more perfect. For example, the use of HP Indigo coating solution is mainly based on the following two reasons: Inking: In the process of using HP Indigo digital printing, due to the high quality requirements of some materials, there may be problems of imperfect inking; Adhesion: HP Indigo electronic inks may have different adhesion problems on different materials. HP Indigo digital coating solution is mainly divided into water-based and oil-based two. Among them, the water-based coating solution has a wider adaptability, and is used for the surface coating of paper (cardstock, pearlized paper, powder paper). Water based coating liquid coating transparent, both environmental protection and non-toxic advantages.
