4. The hue positioning of UV inks can determine the quality standard of uniform UV ink colorants, especially the purity index. If you can solve the problem of poor tone and printers to use a fully automatic color matching system instrument, you can achieve the standard and shorten the production cycle.
5. High cost of UV inks. Whether high prices can be reduced from the formula and process to the general offset ink price, while improving from the hydrogen bond, tension, free energy and other aspects, to improve the attachment fastness, simplify the process and reduce the ozone odor, thereby reducing environmental pollution and increase the print bit.
6. Non-absorbing UV offset non-polar materials, how to improve from the current 5-8 thousand in India / h, to 30,000 in India / h, while the graphics and text is not dissolved in the solvent, aluminum metal PS plate costs, the use of new models more The replacement of thin high-performance polymers becomes a reality.
7. How to easily remove UV ink printing ink film, easy recycling, regeneration and reuse.
8. The problem of how to print the color sequence can be like how other inks, color sequence can be freely controlled, no irritating to the skin, and reduce the number of printing plate, ink guide, ink transfer roller.
The advent of non-absorbable UV offset non-polar inks, in order to dominate the trend, requires the packaging and printing industry in China to establish a crisis awareness of the national brand, in the development of inheritance, innovation in the inheritance, in order to compete in the spirit of the moment, With joint exploration and hard work, the spring sunshine will not be far off.
