When There's No Cure

Both Hahn and Dan Naughton, director of sales and marketing for UV Research (Brea, Calif.), made the point that the photoinitiators are typically the most expensive components making up the UV ink, and also have a major affect on curability and therefore, the speed at which the press can run. Therefore, any modifications to the photoinitiator components by your ink supplier should be something you are very interested in knowing.
