Scott, "UV Offset" and/or "UV Hybrid" inks, such as those used in sheetfed offset lithography, 40" Heidelgerg, Komori, Mitsubishi, Roland, KBA presses, to my humble knowledge, are formulated with a photo-initiator such that they instantly dry when illuminated by a light source containing certain wavelengths of light, in the UV range, such as 360nm. I'm not sure if it's that exact wavelength, though. I confess I have not personally seen much "UV curable inkjet printing" in my young carreer. Please excuse my ignorance but where have you seen them being used? Is that what Mike was referring to? Sorry I missed that entirely.

Good points, Paul.
I have personaly seen many sheetfed presses running UV inks hitting pretty much the same Lab colorimetry on their process color inks than with conventional inks.

Hi Mike
If the UV offset inks match ISO 2846 then the standard Fogra 39/51/47/52 or G7 based profiles can be used as normal for proof simulation and process control on press.
