Digital spray printing is a kind of spray printing using digital technology. With the development of computer technology, digital jet printing technology is a new and high-tech product which integrates mechanical, computer and electronic information technology.
The emergence and continuous improvement of this technology has brought a new concept to textile printing and dyeing industry. Its advanced production principles and means have brought an unprecedented development opportunity to textile printing and dyeing industry.
Ink-jet printing technology
Inkjet printing technology can be traced back to 1884, when pressure needles are applied, droplets fly out. If the direction of droplets is controlled, an image can be formed on paper, which is called fog ink printing. At that time, because of the problems of needle and ink, the effect was very poor, and it was not until 1960 that it formally entered the practical stage. Inkjet technology is used for bar code processing or product serial number printing, which is called jet printer.
Digital jet printing
Digital jet printing is a system engineering, which involves cutting-edge technologies such as CAD technology, network communication technology, precision machining technology and fine chemical technology. It is a product of the integration of information technology with traditional technologies such as machinery, textile and chemical industry.
Because digital jet printing technology involves a lot of calculation and control, it can be said that without today's high-speed computer, there can be no digital jet printing technology. At present, the development of digital jet printing technology is basically synchronized with the working ability of computers, and there is still no sign of weakening the development of computer technology. With the development of computer technology, it can be predicted that the future digital jet printing technology will develop at a high speed. At the same time, the manufacturing technology of sprinkler also benefits from the related technology of integrated circuit, such as etching, precision assembly and so on. This is evidenced by the continuous emergence of modern high-frequency, multi-nozzle nozzles.
Paperless Digital Spray Printing Technology
Paperless digital jet printing can consume high-level products which are difficult to consume in traditional jet printing process. As for natural fabrics such as cotton, because their natural fibers are hydrophilic and disperse dyes capable of digital printing are hydrophobic, they are difficult to separate, so natural fabrics can not stop digital printing directly. However, the digital printing of natural fabrics can be accomplished by using bridging agent. However, there are still some shortcomings in this paper digital printing process. At the same time, paperless digital jet printing is to make dyes into printing pulp, and then print patterns on a special substrate by printing. After the substrate and the fabric are affixed and heated, the patterns on the substrate are transferred and fixed on the fabric, resulting in jet printing waste.
Paperless digital jet printing process, as a novel fabric jet printing process, has played an important role in textile jet printing, and its jet printing products are also popular with consumers.
Digital Inkjet Printer
The output speed is 20, 30, 40, 50, 60, 70, 80, 100 pages per minute or even higher, which can adapt to a wide range of markets; the quality is stable due to the digital technology; the equipment is simple to operate and the working environment is clean; the digital "group" service system becomes a reality, and users are more convenient; the system has low cost and strong competitiveness; It is precisely these characteristics of the digital printing machine that we expect to have broad prospects for its development.
(1) Digital Multifunctional Integrated Machine (DMIC) - This kind of equipment developed on the basis of printer technology is the same in principle as the former, but because they do not master the core technology of high-speed laser printer (except Canon and Xerox), most manufacturers'DMIC can only be in the low-speed (less than 30 pages per minute) market. Competition, even for the market of fax machines and printers. It is difficult for such devices to enter the digital printing market.
(2) Digital jet printer - HP INDIGO is a typical representative of the development of printing press technology, digital technology and electronic ink technology.
(3) Digital jet printer - developed from printing press technology plus digital technology and in-machine direct plate making technology. The production process of digital spray printing is simply to input various digital patterns into the computer through various digital means such as scanning, digital photographs, images or computer production processing, and then to process them by computer color separation spray printing system. Special dyes (reactivity, dyestuff) will be produced by special RIP software through its spray printing system. The disperse and acid main coatings are directly sprayed on various fabrics or other media, and then processed to obtain various high-precision spray printing products on various textile fabrics. Compared with traditional printing and dyeing processes, they have the following advantages:
1. The production process of digital jet printing greatly shortens the original technological route, speeds up the order taking and greatly reduces the cost of proofing.
Because the production process of digital jet printing has got rid of the traditional process of color separation, drawing, film making and screen making, thus greatly shortening the production time. Acceptance of patterns, through CD, E-mail and other advanced means, typically proofing time does not exceed a working day, while the traditional proofing cycle is generally about a week.
In addition, the cost of proofing is greatly reduced due to the simplification of the process. The shortening of proofing cycle and the reduction of proofing cost, which in today's time is money, efficiency is the law of market competition of life, undoubtedly bring more market opportunities to enterprises.
