Traditional printing and dyeing "three high and one low" (high consumption, high pollution, high emissions, low value-added) business model is already in a white-hot competite situation, its market space is gradually shrinking. However, low pollution, low consumption, high value-added, flexible production of digital printing, comply with the green, environmental protection and sustainable development trend, also meet the "small batch, variety, short delivery," the fast Fashion style, in line with the transformation and development of the printing and dyeing industry in the future.
Also, digital printing, as an alternative to traditional printing, is now widely used in garments, home textiles, industrial textiles and other fields. It is suitable for a variety of fibers and blends, including cotton, wool, silk, hemp, polyester and nylon. Undoubtedly, digital printing has a very bright future and has become a rare high-margin industry in the market, attracting many investors to enter this field. According to experts, the next few years will be the golden period for the development of digital printing in our country.
However, can Digital printing really replace screen printing? What are the differences between the two printing process,how to understand and choose?
Printing refers to the use of dyes or paints to form graphics on the fabric surface. Since the development of printing technology, a variety of printing processes, such as screen printing, rotary screen printing, cylinder printing, and digital printing, have coexisted. A variety of printing process for different areas, process characteristics vary, the use of printing equipment and supplies are different.
As a traditional classic printing process,Screen printing, is wide range of applications, the proportion of the printing industry is relatively high, while the rapid development of digital printing in recent years, many people think there will be an alternative trend of screen printing. What are the differences between these two printing processes? In this digital printing and screen printing differences were analyzed.
Less differences in printing material
1. Digital printing is divided into acidic digital printing, digital printing activity, digital paint printing, thermal dispersion printing and decentralized direct printing five categories.It is used for wool, silk and other protein fibers and nylon fiber fabrics.
2. Digital printing reactive dye ink is mainly applied to digital printing of cotton, hemp, viscose fiber and silk fabrics, etc. It can be applied to digital printing of natural fiber fabrics such as cotton fabric, silk fabric and woolen fabric.
3. Digital printing ink coating for cotton fabrics, silk fabrics, chemical fiber and blended fabrics, knitwear, sweaters, towels, blankets digital inkjet coating printing.
4. Digital printing thermal transfer ink suitable for polyester, non-woven fabrics, ceramics and other materials transfer printing.
5.Digital printing direct-jet discrete ink for polyester fabrics, such as decorative cloth, banner cloth, banners and other digital printing.
Compared to digital printing, traditional screen printing don't have much advantages in the type of printing materials. First, there is a limit to the size of the traditional printing of the printing format, large industrial digital ink jet printing machine ink width up to 3 to 4 meters, not only continuous printing but also no limited in length, they can even form a whole production line; In some materials, the traditional water-based ink printing can not achieve better performance, this can only use solvent-based ink to print, and digital printing in any material can use water-based ink for inkjet printing, thus avoiding the heavy use Flammable and non-environmentally friendly solvents.
There is no much difference in material type between digital printing and traditional screen printing. However, there is a limit to the size of the traditional printing format; in some materials, screen printing can only be printed using flammable and explosive non-environmentally friendly solvent-based inks. But digital printing color more vivid.
The biggest advantage of digital printing mainly in the color and the degree of detail on the pattern. First of all, from the color, digital printing ink is divided into dye-based inks and pigment-based inks. Dyes which are more colorful and better than the pigment.
Acid-based digital printing, digital printing active, distributed thermal transfer printing and distributed direct-jet digital printing are used dye-based inks.
Although the use of paint digital printing pigment as colorant, but they are used in nano-pigment paste. Specific ink, as long as supporting the ICC curve for supporting the color to achieve the ultimate show.
Traditional screen printing color, one is based on four-color dot hit color, the second is to rely on prepress ink color to control, color rendering power than digital printing. In addition, digital printing, the pigment ink is used in the nano-level pigment paste, dyes, dyes in water-soluble dye, even the dispersion of sublimation transfer ink, pigment is nano-scale.
Digital printing pattern's fineness is related to inkjet print head characteristics and print speed. Thr inkjet print head drops smaller, the higher printing accuracy, of which Epson Micro Piezo print head for the smallest drop, industrial ink droplets larger than it, but you can print accuracy of 1440 dpi images. In addition, the same printer, print faster, print less accurate.
Screen printing need to make negative plate first, the error during plate making process and the number of mesh have an impact on the fineness of the pattern. In theory, the smaller the screen aperture, the better fitness it is, but more common print 100 to 150 mesh screen, four-mesh dot is 200 mesh. The higher the number of mesh, the greater the chance of blocking water-based ink, which is a common problem. In addition, the time of scraping on the version of the accuracy of the extent of the fine print pattern, the machine printing is relatively better, but manual printing is more difficult to control. Obviously, color and fine graphics are not the advantages of screen printing.
Digital printing has wide range of printing materials, printing products colorful, fine patterns,strong environmental protection, which are its typical characteristics. However, ink jet printing machines are expensive, consumables and maintenance costs are high, which is its drawback. Digital printing products in the washing fastness and rubbing fastness is difficult to enhance; it is difficult to develop a stable white ink, resulting in black and dark cloth can not be better printing; inkjet print head constraints, it is difficult to develop can Printed special effects of ink; printing sometimes pre-treatment and post-processing, more complex than traditional printing, these are the current digital printing disadvantages.However, digital printing will be an unforgettable change in textile printing industry. Although there are still some flaws in digital printing when compared to wire mesh, but it benefits more.
