Although additional retarder can play a role, but the ink on the screen version of the drying rate is still a very difficult problem. Use background discharge method is an effective way to solve the problem of dark garment printing. However, this application can not be called an environmentally friendly way, because formaldehyde content is relatively high, and the pungent smell of background discharge its application is greatly hindered. Many printing manufacturers even prohibit the use of this method in the production process. However, in recent years, ABS ink wholesalers, along with in-depth research and development of ink discharge, and related technology has made tremendous progress. It contains formaldehyde content has decreased odor also have a very significant improvement. In some of the new products introduced in the original discharge agent formaldehyde sodium zinc sulfate has been replaced by an equivalent material wholesalers UV ink surface, and its effectiveness is still quite outstanding emergency. While there has been some breakthroughs in technology, but look forward to discharge ink will have a more long-term development, to encourage the development of more environmentally friendly products, and to maintain this driving force can continue. Water-based ink technology in a few years has made tremendous progress. Thanks to a new type of wetting agents and emulsifiers, ink dried on the screen stencil various original fault has been significantly curbed. Existing some new ink on a screen stencil residence time longer than four to five times before, but did not clog or dry phenomenon. Even water-based ink due to evaporation in the dryer or heat generated by the impact of extreme weather and lose moisture, can be re-emulsification and re-use. Ordinary printing ink consisting essentially of pigment plays the role of color in the ink, it has a direct effect on some properties of the ink. Pigments are insoluble in water and an organic solvent dispersion of a powder of high color, black or white, depending on its source and chemical composition, organic and inorganic pigments into two categories. 1) inorganic pigments are non-ferrous metal oxide, or some insoluble metal salts, inorganic pigments inorganic pigments are divided into natural and artificial inorganic pigments, inorganic pigments are natural mineral pigments. 2) an organic pigment is a colored organic compounds ink, is also divided into two categories natural and synthetic. Now commonly used in synthetic organic pigments, organic pigments varieties, colors more complete, better performance than inorganic pigments. Dye is an organic compound, it is soluble in water, and sometimes is dissolved in an organic solvent, a dye can be prepared from insoluble colored precipitate, called lake pigments, for the manufacture of printing inks.
