1. Direct printing: the printing paste directly printed on a white or light background fabric, treated to obtain patterns of printing methods. Features: Indian pulp chemicals and chemical background does play a role; the process is simple pieces roller printing machine, and low cost. Generally using this method are applied to the printing method. 2. Dial dye (pulp) Printing: ⑴ discharge printing: first dyed fabric, dyed fabric printing on. Paste containing chemicals can damage the background, and the agent does not affect the aid of paste or dye dyed. In the background can be printed on different color patterns, so-called "color dial"; if the paste does not contain dyes available white pattern, called "white dial." Features: background area, deep colors shallow bottom, fine patterns and can not open the flower-shaped, only use discharge printing; printing process more complicated than direct printing. Dial dye principle: ① background dye - impatience reductant (usually azo direct, reactive and acid dyes) ② color dye - resistant reductant (vat dyes or acidic dyes triarylmethane, heterocyclic dye) ③ reductant - stannous, carved white block, etc. ⑵ dial 德古林 paste printing paste previously printed on large surface were smaller dial white printing, reducing resistance when the paste containing different dyes mixed colors , you can get a small set of multi-color effect. From the statistics show that the world's traditional printing mainly in Asia, including China, Southeast Asia and India, accounting for 66% of the total amount of printing. In traditional Chinese printing accounted for nearly 30 percent of global production, but digital printing is less than 1% of the domestic printing, a huge room for growth. Nozzle and ink for digital printing is very important, the importance of ink embodied in what areas? If that is the digital printing engine nozzle roller printing machine manufacturers, and digital printing ink is fuel, no fuel even if we have good equipment the system can not be activated. Good quality ink, relative to the nozzle will reduce the wear and tear, printhead life will naturally increase; the poor quality of the ink roller printing machine will not only hurt the nozzle, and even shut down will affect printing. Ink composition containing pigments, humectants, surfactants, biocides, and other additives, etc., pigment printing color is the key to achievement, with good pigment, ink quality is half the battle, while the other half will depend on the solvent Recipe combination to enhance the print properties.
