S I G N & D I G I T A L G R A P H I C S • May 2017 • 53 available, it's best to chose one that is rec- ommended by your ink manufacturer in order to ensure best compatibility. More Pointers Stratojet's Garcia says that when han- dling glass, it's a good idea to use gloves— such as Dermatril nitrile gloves. "These gloves are chemical resistant and do not generate dust particles," he says. "Gloves are used to avoid leaving fingerprints on the glass because fingerprints compro- mise adhesion. In addition, always set the printhead height adjustment following the manufacturers recommendation and set the UV lamp curing power to max." Roden says that it's always a good idea to provide increased printhead mainte- nance and cleaning when printing onto reflective substrates like glass or mir- ror to ensure the heads continue to jet properly. UV light reflected back to the printheads can cause ink to cure where it's not wanted. Run Tests Hope adds the key to printing on glass with UV inks is to always test the ink and substrate combination to ensure that the proper adhesion and durability are achieved for the intended application. "Once the adhesion is established, print- ing on glass is no different than printing on any other substrate. One stipulation is additional precautions that would be necessary if the surface is highly reflec- tive such as mirrored glass. In that case, it is strongly suggested to mask off any areas that are not being directly printed on, and to run maintenance cycles more often to reduce the chance of ink curing on the print heads," he concludes.
