I could have agreed with you before I tried the same inkjet printed
film with fluorescent exposure box and Hg arc with nice collimation.
When I saw a dramatic difference side by side between PCBs produced
by both methods, the answer was obvious to me. Another aspect to
watchfor is wavelength. Some arists use 420nm for their UV process
(platinum) while Revlon is about 350nm if I remember correctly. Mike
