We use UV ink to print our bottles. UV Curable screen printing ink is a 100% solid system: that is, it essentially does not contain solvent that must evaporate during the curing phase. The cure takes place through the interaction of the ink ingredients and a strong UV (ultra violet) light source in a dryer, or more accurately, a reactor.
Since UV contains little or no solvent, there is a lot of interest in using it because of the lack of VOCs (volatile organic compounds). Either reducing VOCs or eliminating the need to report them both have appeal. The reduction in VOCs also has an appealing environmental effect |
