With the development of technology and the increasing number of digital printing enterprises in the market, the choice of ink system also presents diversified development trend. Because each kind of ink system will have its own advantages and disadvantages, so more understanding of these ink system characteristics, can recognize the current ink most core development trend. Here is a summary of the latest development of various types of ink...
Water-based ink is also called watermark ink or water-based ink. Water-based inks are generally based on dyes and pigment formulations. Their service life in a few days to a month, and need to be used with special coated ink-jet printing substrates, the owner if by coating printing ink absorption, so the price is quite expensive, but the price is relatively cheap water-based ink, and no subsequent processing problems.
Water-based ink can be duplicated in the color field is almost the largest ink system. As a result, more and more printing companies are starting to use water-based printing solutions.
Solvent based ink.
Solvent - based inks are mainly colored by infiltration to substrate surface. They are mainly developed for ethylene products and are the most used ink systems in the inkjet printing market. Solvent - based inks can provide users with longer service life without having to cover film, but they need to be heated during printing and drying. True solvent - based inks contain VOC (volatile organic compounds) and require a printing plant to take ventilation and other air treatment measures. Overall, apart from some areas where the air quality requirements are more stringent, the sales prospects of solvent - based inks are very optimistic.
Environmental protection or low solvent ink.
Environmental protection or low solvent ink can be used in coating or non - coated substrate. When they are printed on the coated substrate, they can control the expansion of the dot. When they are printed on non-coated substrate, the heater/dryer is required to control the dot expansion. Environmental or low solvent ink is cheaper than real solvent ink, and does not contain VOC, eliminating the problem of air handling. Since the life of this ink is similar to that of solvent based ink, users can extend their durability by covering film. Therefore, the future is also one of the mainstream ink.
The eco-ink, which USES ethyl lactate, is still an emerging technology, and its raw materials come mainly from crops such as corn. Ecological ink in the printing need to set the heater and dryer to higher temperature, solvent extracted from plants, rather than oil solvent, so this kind of ink was within the scope of green products. If UV ink doesn't beat the eco-market before it goes public, it will certainly be able to break into its own niche in digital printing.
Hot sublimation ink
For textile and clothing printing plants, thermal sublimation ink is a good choice, this basic ink technology has not changed much in recent years. People in the use of the ink, the first to print them onto a piece of transfer paper, and then by heating and pressure convert ink from solid to gas, and its penetration into the textile fiber. Due to the rising of the small print market, the utilization rate of thermal sublimation ink will continue to grow.
UV ink has always been in the process of development, and more and more printing plants began to adopt new UV digital printing ink. When UV curable ink was first introduced to the market, they had a certain problem in terms of fragility, adhesiveness and solidification. But with the emergence of new UV ink, all problems have been solved. The new product has a higher viscosity and stronger flexibility, can meet the demand of the roll to roll printer, and they are in color gamut and the diversity of the anti-counterfeit printing ink formula also products has made great progress than before. The new UV ink is also known as "cationic UV ink", which USES cold UV curing technology, which can be dry instantly, without waiting for 24 hours. In the days to come, the ink will go into the digital printing market, which is guarded by solvent-based ink, especially in the field of body advertising and strip printing.
