Status of Solvent-based Ink

Jan 21 , 2020

Solvent-based ink refers to an ink system formed by dispersing pigments or dyes in a carrier using an organic solvent or a solvent-based polymer film-forming agent as a carrier. Due to the high durability of printed image quality and low raw material cost, solvent-based inks have a huge market in large-format and wide-format applications. Although solvent volatilization is likely to cause environmental pollution, which limits its development in the European and American markets, solvent-based inks are still booming in the Chinese ink market. To cope with environmental pollution, a new type of ink, ECO-solvent Ink, has begun to develop rapidly. This kind of ink with less environmental pollution will be the development direction of solvent-based ink in the future.

The Desktop PVC Smart Card Printer Manufacturer will discuss the current status and development trends of the solvent-based ink market positioning, composition characteristics, and emerging products.

Taking printing speed as the standard, solvent-based inks are mainly used in medium-speed printing for classic wide-format printing and industrial wide-format printing; while water-based inks are mainly used in homes and offices with low printing speed requirements; high-speed inkjet printing The market is 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 reducibility, less lateral diffusion on printing materials, and fast drying speeds. Therefore, no special treatment of printing materials is required. , Direct printing on uncoated materials such as adhesive films and mesh fabrics. If solvent-based inks use high-quality pigments, the printed products will have good UV resistance without the need for a film. At the same time, the volatile characteristics of this ink can also make the dried ink film thinner. Solvent-based inks can adapt to a variety of printing materials, printed images have better durability, and their prices are lower than water-based inks. So solvent-based inkjet printers have opened up billboards, body advertising, and many areas where traditional printing was previously impossible.

The disadvantage of solvent-based inks is that during the drying process, harmful substances are emitted into the air through the volatilization of solvents, which affects indoor and outdoor air quality. Therefore, you need to pay attention to some problems such as the daily maintenance of the spray head and solvent volatilization. It must be used in a well-ventilated environment. These shortcomings have limited 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 can the application of solvent-based inks achieve greater growth. In fact, due to technological development and strict R & D testing, high-quality UV inks are becoming competitors to solvent-based inks. In terms of three important ink evaluation factors, drying speed, substrate adaptability, and application range, UV inks exceed solvent inks. At the same time, UV Inks do not contain volatile organic compounds (VOC), which has quite 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 fields, their inherent advantages will still increase their proportion in the domestic market for a longer period of time. At present, relevant ink manufacturers are also improving the ink formula, and have introduced environmentally friendly solvent-based inks and environmentally-friendly solvent-based inkjet printers that do not contain harmful substances. The new generation of solvent-based inks will be more complete and harm the environment Will get smaller and smaller.
