Re: [QuadtoneRIP] UV transmisison characteristics of Epson K3 inks

2014-03-04 by <sanking@...>

Selecting inks for use in a QTR profile for alternative printing with UV processes definitely must have other considerations than those used in line or halftone printing in silkscreen. It is also quite different than the requirements for making monochrome inkjet prints on paper. I am attaching a table that shows the UV readings of the K3 inks on Pictorico, as measured with a UV densitometer at 25%, 50%, 75% and 100%.
