Product Description
UV inks do not dry in the air so they do not tend to plug the cells. There in no component that evaporates so there is no
need for clean-ups between press runs. The press could even be left over the weekend without cleaning and be ready to
go on Monday!
.
UV inks act like liquid plastic. As the ink is exposed to concentrated UV radiation, a chemical reaction takes place
during which the photo-initiators cause the ink components to cross-link into a solid. No material is removed so nearly
100% of the delivered volume is used to provide coloration. Assuming all of the ink transferred from the cells to the
substrate, to attain the color density previously attained with water based ink, the anilox roll would have to be specified
to delivered about 35% less ink to the substrate. Of course, viscosity will play a key role in determining the percentage
of ink to transfer (transfer factor)..
