Advantages of digital printing
1. Digital printing dyes are inkjet on demand, which reduces the waste of chemicals and wastewater discharge; the noise is low during inkjet, it is quiet and clean, there is no environmental pollution, and the process of green production is realized.
2. The printing process simplifies the cumbersome process, cancels the complicated screen making and color matching process of traditional printing, the cost of receiving orders and proofing is greatly reduced, the delivery speed is fast, and instant supply can be realized.
3. The process has a high degree of automation, the whole process is controlled by computer, and can be combined with the Internet to realize the e-commerce of textile production and sales.
4. The production flexibility is strong, which means that the materials for printing are flexible, without restrictions on color and position, and can make textile fabrics achieve high-end printing effects; the printing quantity is flexible, especially suitable for small batches, multi-variety, and personalized production; printing Very easy to organize
5. The colors are colorful and vivid, and the printing fineness is high. In the printing of high-precision patterns such as color gradients and moiré, digital printing has unparalleled advantages. Inkjet printing can express up to 16.7 million colors, while traditional printing methods only have a dozen; The resolution is as high as 1440dpi, while the traditional printing process can only reach 255dpi (DPI is the expression of resolution, which means the number of vertical and horizontal dots in a unit inch).
shortcoming:
(1) Slow printing speed
(2) High cost of ink
Digital printing does not need to make screens, and the cost advantage of small batch production is much higher than that of traditional printing. However, because its ink price is relatively expensive compared with traditional printing color paste, the cost of mass production is still higher than traditional production.
(3) Color accuracy
Compared with the spot color printing of traditional printing, that is, each set of colors is adjusted separately, the color measurement and matching system of the computer can achieve high color accuracy. Even if a certain type of color paste deviates, it will only affect one set of colors, while digital The printing is CMYK mixed-color printing, all colors are mixed by four-color inks, a little bit of external influence, such as ink differences, differences between print heads, and slight changes in the environment during the printing process, will affect a series of mixed colors. Color Accuracy. It is easy to produce poor machine performance, especially for sensitive colors mixed with inks, such as gray, brown, dark green and red.
Digital printing can be said to be indispensable in personalized customization, especially in fabric clothing. After digital printing, most of the cutting is done by laser cutting.
