Digital printing technology It is a process of realizing clothing printing through digital image processing and printing technology. It mainly uses computer-aided design software and ink jet printer, Spray out the desired patterns and colors on the textile. Compared with the traditional printing technology, digital printing has many advantages. First, it prints faster and can be mass-produced. Secondly, it can provide more accurate patterns and color effects, making the printing pattern clearer, more vivid, more vivid. At the same time, digital printing technology can also realize personalized printing, according to the needs of customers for design and production. In addition, digital printing is also environmentally friendly because it uses renewable resources and reduces the pollution caused during production. Therefore, digital printing has become an important development trend in the printing industry.
Digital printing can be divided into two categories from the production process: digital transfer printing and digital inkjet printing. The content of the last section has involved digital transfer printing, this section introduces digital inkjet printing. Digital inkjet printing refers to the computer production processing of various digital graphics input computer, then through the computer color printing system processing, by special RIP software through the printing system will be all kinds of special dye (active, dispersed, acid paint) printing directly to all kinds of fabric or other medium, then after steaming, water processing, in all kinds of textile fabrics required for all kinds of high precision printing products.
Digital inkjet printing according to the variety of fabric and dye types can be divided into acid inkjet printing (silk, nylon), active inkjet digital printing (cotton, hemp, silk), thermal sublimation inkjet printing (polyester), paint inkjet printing (almost all materials of cutting, clothing). According to the form of the fabric, it is divided into continuous inkjet printing and garment inkjet printing. According to the characteristics of different elasticity and fragility, guide strip direct spray printing and non-guide strip direct spray printing appear.
Digital printing technology gets rid of the traditional simulation mode of printing color separation, production and network making, and has the characteristics of simple operation, high efficiency, no pollution, low investment and high return, which has brought unprecedented opportunities for development to the textile printing and dyeing industry. But it needs to combine color management to achieve color reproduction.
Advantages of digital printing
(1) Simplify the work process and shorten the work cycle
The production process of digital printing gets rid of the process of traditional printing color separation, publishing and plate making, thus greatly shortening the production cycle. The whole process only needs a few hours, and the traditional proofing cycle is generally about a week digital printing to do instant, the production batch is not limited, really realize the small batch, many varieties, rapid response of the production process.
(2) Clear image, rich color, and quality assurance
Due to the limitation of traditional printing patterns, the design and color of many images can not be printed, mainly because the image is complex and difficult to divide colors, too much color is difficult to locate, too many colors is difficult to adjust colors, resulting in the quality of printing is difficult to control. The digital printing process, controlled by a computer, has 16.7 million colors, breaking the limits of traditional printing. Especially in the color gradient, moire and other high-precision pattern printing, digital printing has more incomparable advantages in technology, but also to ensure the effect and quality of printing.
(3) Simple operation, strong stability, and no technical requirements
Traditional printing needs professional color separation film proofreading personnel, professional plate-making personnel, professional color mixing personnel in every link of the problems can not guarantee the effect of the final printing. And digital printing only needs a graphic image designer can complete, simple operation, strong stability.
(4) print according to the need, reduce waste, low rate of defective products
Digital printing from proofing to finished production, can control the material loss, unlike traditional printing waste a lot of raw materials.
(5) Meet the growing personalized needs
According to the personal needs of consumers, the electronic documents can be directly exported to the inkjet printing machine, and the product can be formed after printing and molding, to achieve rapid and personalized consumer demand.
(6) Green protection, environmental protection and pollution reduction
Pollution-free production, digital printing does not need to wash the flower plate, also does not need to use a lot of water to wash the printed fabric to recede the surface floating color, so there is no serious environmental pollution caused by dyes and other raw materials.
Current problems with digital printing
(1) High production cost
Although digital printing production has improved significantly in energy saving and environmental protection, the cost of consumables is too high, and the high price of digital inkjet rinting machine and ink has become a major obstacle to the popularization of products.
(2) Slow production speed
The speed of digital printing machine is generally 60m2 / h, the production efficiency is low, it is difficult to achieve the scale production of digital printing products.
(3) It needs to be matched with the corresponding post-processing equipment
Inkjet printing after steam, baking and curing and washing treatment, the corresponding equipment, the economic strength is not strong manufacturers are limited. If the original dye printing curing and reprocessing equipment, only to increase the digital jet printing machine, the economic pressure of the manufacturer can be relieved.
