At the same time, clothing has become increasingly popular short-cycle, the pattern changes faster and faster, producing increasingly high demand for bulk orders getting smaller and smaller, flower-rampant piracy. Although the printing business in the traditional way of printing a stamp on the introduction of CAD systems, laser Imagesetter, flat screen, the rotary-jet, spray wax and other network system of digital tools to improve the processing, printing and dyeing mill, but is seems that the concept of factory pollution Has created a deep impression. At the same time, in the international printing and dyeing our exports are increasing, the environment, including the “non-trade barriers” hindered. On the current technology, the digital printing area of the city to resolve the many problems printing the best way.
Second, digital printing machine’s technical characteristics
Digital jet printing systems and printing process compared to traditional printing process has been a fundamental change to simplify the design process, jet printing, post-processing, save the text description, the producers (or network system, sculpture), the screen (or Rotary) installation, simplifies debugging equipment, such as the mixing process; to simplify the process save the film plane (or network system, engraving machine), and other equipment and film, screen, the consumption of materials such as the drum.

Three digital printing technology track
Whether the use of traditional printing from flat screen, rotary screen can not be separated from network, but the plate by the cost and time consumption, can not be satisfied no matter how small, multi-stamp species of modern trends, the development of a free version, without the pressure of the digital Printing. The basic principle with the same ink-jet printers.
Ink-jet printing technology can be traced back to 1884, the Americans C. H. Richard put water in the syringe, needle on the fly out exerting pressure drops, if droplets direction control, we can form images on paper, printing ink as the fog. At that time, because the needle, ink problems, poor results until 1960 before formally entering the practical stage. 10 years ago to ink-jet technology for processing and product serial number bar code printing, said Pen Maji.
Digital jet printing is a systematic project involving CAD technology, network communications technology, precision machining technology and cutting-edge technology, fine chemicals and technology, information technology and machinery, textile and chemical technology integration of traditional products. As the digital jet printing technology involves a large number of computing and control, you can not say that today’s high-speed digital computer, there can be no jet printing technology. For now, digital jet printing technology is basically a computer with the ability to work simultaneously, and the development of computer technology is still no sign of abating, with the development of computer technology can be expected in the future of digital jet printing technology will have high-speed发展. At the same time, head of manufacturing technology also benefited from the integrated circuit technology, such as etching, precision assembly, and so on. Modern high-frequency, multi-nozzle head of emerging on the proof of that.
90 popular computer technology step by step, straight-jet digital printing machine, to 1995 on the carpet, wall and so on the rough design on textiles has been a mature application. ZIMMER Austria’s lead in the digital display for carpet jet printing prototype, resolutions 9-18, the use of spray valve technology, not the usual sense of the nozzle; their production rapidly, up to 16/min. However, due to a large spray droplets, low-resolution, in regard to clothing fabrics can not be applied.
In 1995 there have been on-demand ink-jet digital printing machine, when the main hot-foam nozzle, the resolution of 300dpi, then gradually developed to 600dpi, 4-color-based, the basic fabric can be applied.
1999-2000 using piezoelectric nozzle jet digital printing machine with more countries on display, including the Netherlands, Japan, Switzerland, the United States, Italy and China Honghua, a resolution of up to 360 ~ 720dpi, 6 / h, due to Piezoelectric ink-jet nozzle of the minimum amount is very small (textile applications can be achieved 6p1), produced relatively sophisticated design, color and more uniform nature, so popular, is also gradually expand the application area.
At present, all kinds of new digital jet printing machines have appeared, mainly piezoelectric nozzle; the highest printing speed of 90 from the year 1 / h, 2000-year 6 / h to the development of 080-150 / h; the use of dyes from the 4-color development 6-8 to the color and color 2X6-8; application process has become more sophisticated; control software features improved step by step.
This shows that the digital jet printing technology is basically in a row from the shoot-on-demand jet to the development of the heat from the nozzle to the bubble-type piezoelectric nozzle changes from 6-8 to 4-color color change. At present, digital printing technology is crowded and has shown, the trend of letting a hundred flowers bloom.
From the basic theory of production equipment, from the application of technology to the development of the dye, as well as equipment, software and color control in a comprehensive study of the development.
90, ITMA exhibition on digital printing products from a display manufacturers to develop 5, the last 5 years ITMA exhibition on digital printing products manufacturers display the development of high-speed, it was reported that in the digital printing ITMA2003 on the number of exhibitors Up to 23, including equipment, dyes, technology and other aspects. In particular the traditional printing machine manufacturers and dye maker has invested with great enthusiasm, such as STORK and ZIMMER have been launched 4 models of digital printing machine, CIBA, BASF, Dystar such as dyes and auxiliaries of the top manufacturers as far as we They have to understand the introduction of digital printing dye for a number of improvement. Even Taiwan’s Ministry of Economic Affairs on December 5 last year with the signing of a number of business R & D Alliance, the development of “industry-wide use of digital ink-jet printing technology,” These international companies with so much effort to develop a digital printing machine to reflect their Textile digital printing direction of the judge.
Four digital printing technology and advanced production
At present, digital printing technology can be applied not only personalized, small-volume production printing and dyeing enterprise, as well as proofing, and has entered mass production in the area. In Europe, less than 500 meters from the order is basically a digital printing machine to play, only the use of new digital printing system has a number of dyeing and printing enterprises, and network design, network production, combined with sales network and achieved good economic results. It can be said that we are ushering in a new era of digital textile.
We have to help Hong Kong, Shenzhen, Shanghai and other enterprises to establish a number of digital proofing the printing shop to improve overall economic efficiency of enterprises. We have been in Thailand, Malaysia and the establishment of a number of domestic mass production of digital printing products factory, all the profits into the state. Now we are entering a new era of economy and booming textile industry of the last century compared to the traditional economy of the times, textile production environment has undergone major changes, see Table 3
The traditional economy of the new era of economic times
Customers can choose to regional and global
Consumer demand for cost-effective to meet the basic needs of personalization, diversification
The relative stability of the market rapidly changing, unpredictable
Market demand for low-cost, high-quality customer-oriented, fast delivery
Market standardized way, serialized, single-volume, low-volume, multi-species
Technical resources relative concentration of the global distribution
Elements of the flexible production cost competitive with the response speed
As can be seen from Table 3, in the present and future development prospects, maintain high-volume production of textiles changes in the circumstances, particularly the first printing of textiles to the current mode of production that can not adapt to environmental changes.
In order to survive in the new development in the fierce global competition to win the victory, enterprises must change the product manufacturing strategy, to seek the implementation of the new mode of production to achieve time to market, improved product quality, reduce product cost targets, in order to Customers can accept the price of time and achieve customer customization of products, mass customization is the response to this demand.
Mass customization is a new mode of production and management, and its objective is to provide the benefits of high-volume production of customized products, this is the ideal manufacturing production. Therefore, mass customization of a concept put forward by the aroused wide concern in recent years become a world-wide research, some enterprises have been successfully implemented in the 21st century is becoming a mainstream mode of production for the manufacturing sector.
Mass customization in the system under the guidance of thinking in order to optimize the overall point of view, to fully tap the business potential in the standardization of technology, computer technology, modern design, concurrent engineering techniques and ideas with the support of, and ultimately According to the special needs of each customer in order to provide efficient mass production of customized products. Mass customization of the integrated high-volume production of low-cost advantages and customization to meet individual customer, the advantages of diversification needs, so that enterprises can adapt to rapidly changing market, customers in an acceptable time and price to provide customers Really need. Mass customization with the traditional distinction between high-volume production as shown in table 4.
Mass production and mass customization
Through the heart of the stability and control access to the realization of the efficiency of product variants and customization
To the target almost every customer will be able to afford the low-cost and low-cost development, production, sale, transportation of goods and services. With sufficient degree of flexibility and customer development, production, marketing, transportation, nearly every customer wants to get the goods and services.
The key characteristics of the product-centric; stable demand; large and unified market; product development chief Zhou collapse; low-cost, consistent quality, standardization of goods and services. Customer demand for the center; dynamic demand; fragmented market; shorter product development cycle; low-cost, high-quality, customized goods and services.
Mass customization based on the objectives of the benefits of mass production of customized products for users, the product is to be customized, personalized; to the manufacturer, the product is mainly used The formation of high-volume production methods.
Digital jet printing technology and gradually mature, successful solution to this problem, just a few primary colors could be released on 10,000,000 kinds of colors, can be made within 24 hours to provide customers with sample, it is convenient for customers according to the needs of small organizations, Even a single production, flower color can be arbitrary; when digital jet printing technology and further information network technology, the network will be able to carry out three-dimensional modeling and tailored to achieve fully personalized business model.
For example: Cus ~ mClmh. com is a custom-made clothing enterprises in the use of digital printing technology, one of the manufacturers. Their products include computer printing to produce a trademark fabric, ties and scarves.
Cus ~ mClo out. com application of the six-color ink-jet printing machine. Customers from 12-150 kinds of different patterns of arbitrary choice, you can use the page template provided by their own design, or paid by the company in accordance with the wishes of their own tailor-made. In this way feasible, a large number of stocks can be avoided entirely caused by the trouble.
In short, the emergence of digital printing technology and successful applications in the textile industry is a major technological revolution, which has landmark significance, digital printing brought about by the global economic and social benefits will be particularly great powers China textile printing and dyeing have a far-reaching Impact. And various industrial upgrading and transformation, the new digital jet printing technology is both a challenge and an opportunity for Chinese textile enterprises in the coming change must seize the opportunity.
