What is UV ink? Advantages and applications of UV ink

UV printing technology

UV is the abbreviation of English Ultraviolet Rays, namely ultraviolet light. Ultraviolet (UV) is invisible to the naked eye. It is a piece of electromagnetic radiation other than visible purple light with a wavelength in the range of 10 to 400 nm. Ink characteristics UV Curing photocurable ink (photoinitiator function) is a brand new green technology developed in the 1970s. It was developed around the world 10 years ago, and a large number of related products and equipment were manufactured. Non-toxic inks complying with EU RoHS standards do not contain volatile organic compounds VOC (cadmium, lead, mercury, hexavalent chromium, odorous biphenyl and odorous diphenyl ether), nor do they contain aldehydes commonly used in general interior decoration. The environmental pollution is small, it will not cause harm to the human body, the curing speed is fast, the energy is saved, the quality of the cured product is stable, and the fixation is good. UV-curable inks are compatible with inkjet equipment and are suitable for a variety of hard substrates. Weather resistance: indoors, the color can be kept for twenty years. Placed outdoors, the direct sunlight color can remain unchanged for four years. Adhesion: After 100-test test, the adhesion of all kinds of materials is in line with the standard.

Advantages of UV

1. Excellent color density performance
The color saturation is high and the ink dots are clear and of good quality. Compared with traditional printing, UV printing can produce higher quality color effects, and satisfactory results can be obtained for prints with stricter colors.

2. Immediate drying greatly improves production efficiency
The drying speed is fast, and it usually takes several hours or more for the printing to wait for the ink to dry completely. UV printing can be completely dried in 1 second to several seconds, the difference is very obvious, and the production efficiency is greatly improved.

3. Reduce costs and reduce risk
Generally, after the completion of the traditional printing, there may be a color change within 48 hours, and it is necessary to leave the space for drying, and the UV drying speed is fast, and there is no need to wait while printing, which saves space and cost.

4. Stronger print quality
The light resistance and abrasion resistance of printed matter are better than traditional printing, which can greatly reduce the loss caused by friction during the use and transportation of the product.


5. Environmental protection without pollution
UV inks contain no solvent, no solvent volatilization, no pollution to the atmosphere, UV printing is environmentally friendly printing. The amount of printing ink is comparable to that of a conventional four-color process, but the waste of UV ink is less.
