Printing in the digital age since the 1980s, the research and development of printing materials, equipment and processes in China has made printing play an advantage in the competition with other printing methods. At present, about 70% of large format color printing uses spot color printing, and nearly 30% of large format color printing uses four-color overprint, and the proportion of four-color overprint is still increasing steadily. Many types of inks can be used for plate printing, namely: oil-based, water-based, synthetic resin emulsion, powder and other types of inks. The missing printing method of plate printing determines its characteristics of thick ink layer, bright color and strong hiding power. The thickness of ink layer can reach 30 ~ 40 μ M (the thickest ink layer in all printing methods), with strong relief decorative effect. Due to the use of elastic and flexible plate, plate printing can be applied on the surface of substrate of various materials and shapes

printing can use inks or coatings with coarse particles and different solvents to adapt to the printing of different types of substrates. For example, the inks only used for paper packaging decorative materials include glazing paint, UV imitation gold etching ink, foaming ink, fragrance ink, pearlescent ink, liquid crystal ink, phosphorescent and fluorescent ink, crystalline gloss ink and UV "ice flower" ink

with the continuous expansion of application fields, printing has been paid more and more attention. Plate printing can print all kinds of plastics, textiles, metals, glass, ceramics, etc. it is suitable for commerce, advertising, decoration and other fields. Whether soft, hard or fragile; Whether plane, curved surface or spherical surface can be printed. Combined with electrolytic process, bronzing process, calcination process and plastic forming process, plate printing can produce different types of artworks

digital printing is now stepping into print

as we know, digital printing is also "instant printing", which is especially suitable for small batch of timely printed materials, such as restaurant menus, instant advertising leaflets, etc. if these are realized by the traditional printing method, it may not be a good way. However, the current era is in great need of this kind of timely thermal insulation effect and small batch printing with proven use effect, Even if it is too much, the advantage of printing is also clumsy here, and digital printing came into being. Now, some inkjet printers can print directly on uncoated self-adhesive vinyl substrates, banner vinyl substrates, polyester flags and silk, and also on hard substrates. In order to make color printing prosperous for a long time, it is necessary to generate square wave pulse signal with the same frequency as quartz crystal in the operation length and substrate range to maintain strong competitiveness

digital printing continues to develop, but not as fast as expected. Because the real difficulty in predicting the large format printing market is that it has not formed a market at all, digital printing still has its great limitations in the current era, and the shortcomings and disadvantages of digital printing can not be overstepped

in the era of digital printing, technology determines who is the winner of large format image printing. You should be a professional image studio, printer or label maker to win customers. A customer who needs a large outdoor area to show that the machine damage is about to start the poster will go to a printer, because no other technology can be more competitive than its price. However, if a buyer needs four multi-color panels for exhibition, the image studio is the natural choice. In fact, label makers, printers, image studios and fast printers rarely compete with each other, because their different technologies correspond to different customer groups

when technology reduces the technicalization of printing itself, other processes in the production process such as design, communication, color management and binding become more and more complex. Files and copies often appear in various formats. Sometimes a file made with an incompatible program cannot be input and opened at all. Many wide width equipment can not print out the registration line and cutting line, which makes it very difficult to register and cut. Sometimes new post press processes must overcome the limitations of digital printing inks, toners or media. Printing only accounts for 30% of all work, while other management work has occupied a major position. The performance of any digital printing system does not match the color expression ability and performance of plate printing. Therefore, digital printing is not a simple thing, nor can the establishment of a new digital printing company make customers turn to digital printing. Instead, it requires many senior talents with rich experience, keen market mind and a number of competitive technologies

will digital printing replace plate printing as the preferred way to produce wide color images? From the perspective of value, it is almost certain, but this does not mean the elimination of block printing. Many major printing companies have invested heavily in new machines and technologies, including multi-color printing machines and UV curing inks, as well as digital printing for proofing and short version printing

we must also remember that the complex manufacturing process and strict requirements for inkjet inks determine that digital printing may never be as cheap as plate printing, flexo printing and offset printing. Especially for the long-term printing industry, digital printing cannot be cost-effective compared with traditional methods, but in the long run, it is necessary to supplement the market share and income lost by any printing industry

as the computer digital processing technology continues to mature, a major technological revolution has taken place in the printing plate technology, which is the computer film free direct imaging plate making method CTS. There is a template direct imaging plate making method. The printing plate is coated with a chemical coating instead of photosensitive glue. Instead of spraying hot wax, the computer is used to scan the original image directly on the template coated with chemical coating, and then rinse off the chemical coating with water to form an image. Another direct imaging method for plate making is to use a computer to scan the laser image directly on a special metal platform, which can eliminate the silk and photosensitive glue, and does not need a complex process. The template made by this plate making method has no deformation, alignment and high printing precision, which is the future development direction

digital printing is a rising star with incomparable advantages and is the direction of future printing development. However, the excellent quality of printing also makes it a wonderful flower in the printing industry. We don't want to see it disappear and hope it will be stronger. In fact, perhaps the combination of digital printing and printing will make the printing industry more dynamic and vibrant
