Do You Know Solvent Ink

Nov 17 , 2020

Solvent-Based Ink refers to an ink system formed by using an organic solvent or a solvent-based polymer film-forming agent as a carrier to disperse a pigment or dye in a carrier. Due to the high durability of printed image quality and low raw material costs, solvent-based inks have a huge market in large format and large format applications. Although solvent volatilization may cause environmental pollution, thereby limiting its development in the European and American markets, solvent-based inks are still booming in the Chinese ink market. In order to deal with environmental pollution, new inks, ECO solvent inks, have begun to develop rapidly. This kind of ink with less environmental pollution will become the development direction of solvent ink in the future.

Regarding printing speed as the standard, solvent-based inks are mainly used in medium-speed printing, classic large-format printing and industrial large-format printing. Water-Based Inks are mainly used in homes and offices that do not require high printing speed; the high-speed inkjet printing market has been firmly occupied.

Generally speaking, solvent-based inks are more popular in the field of outdoor advertising printing. Compared with water-based inks, solvent-based inks have bright colors, good color reproducibility, less lateral diffusion on printed materials and faster drying speed. Therefore, no special treatment is required for the printed material. , Print directly on uncoated materials. If the solvent-based ink uses high-quality pigments, the printed product will have good UV resistance without the need for film. At the same time, the volatility of this ink can also thin the dried ink film. Solvent-based inks can adapt to a variety of printing materials, the printed images have better durability, and its price is lower than water-based inks. Therefore, solvent-based inkjet printers have opened up billboards, body advertising, and many areas where traditional printing was not possible before.

The disadvantage of solvent-based inks is that in the drying process, harmful substances will be emitted into the air through the volatilization of the solvent, thereby affecting the indoor and outdoor air quality. Therefore, you need to pay attention to some issues, such as the daily maintenance of the nozzle and solvent evaporation. Must be used in a well-ventilated environment. These shortcomings limit the growth trend of the ink market in the United States and Europe. Only by strengthening the use of non-hazardous substances or environmentally friendly solvents, the application of solvent-based inks can achieve greater growth. In fact, due to technological development and strict R&D testing, high-quality UV inks have become competitors of solvent-based inks. In terms of three important ink evaluation factors, drying speed, substrate adaptability and application range, UV ink surpasses solvent ink. At the same time, UV ink does not contain volatile organic compounds and has good environmental benefits. Therefore, UV Ink may become the main ink for industrial inkjet printing in the future.

Although solvent-based inks have been challenged by UV inks in some areas, their inherent advantages will increase their proportion in the domestic market for a relatively long period of time. At present, relevant ink manufacturers are also improving ink formulations and have introduced environmentally friendly solvent inks and environmentally friendly solvent inkjet printers that do not contain harmful substances. The new generation of solvent-based inks will be more complete, and the harm to the environment will be less and less.
