The watermarks on 7930 are a pain. I really dont see why they do it. My company tried to do real estate
signs with 7930 instead of 3290 (They were told 3290 is eventually being phased out). And the customers sent it right back. Even if you can't see it unless your a FT away, it looks kind of unprofessional.
I will say it reflects so much more than 3290 though... I can print on 3290 with our UV Flatbed all day with no issues, I printed 2
signs on 7930, and within an hour the heads were clogged and I had to do 4-5 flushes to fix it.
