With Canson Platine (a 310gsm paper; I don't know its thickness in mils), and the R3000, I've had to go to a paper thickness of 5 and the wide platen gap to avoid headstrikes. At the 4 setting, and wide, I often, but not always, had headstrikes. The ink would smear at the edge of the paper, at the end of the print. I am printing sheets, and often slightly bend back the sides of the paper at the trailing end to try to avoid the strikes. That has not always worked, and I've recently moved to the 5 setting with better results so far. I'm printing up several portfolios right now, so I'm really putting the printer through its paces. I do like this printer. --Barbara
The only data I have on Canson papers is:
Arches Aquarelle Rag 240 g/m2 = 18,42 mil, 468 µm
Arches Aquarelle Rag 310 g/m2 = 23,38 mil, 594 µm
Edition Etching 310 g/m2= 18,65Mil, 479 µm
Rag Photographique 310 g/m2 = 18,34 mil, 466 µm
Montval Aquarelle 310 g/m2 1 = 19,52 mil, 496 µm
... where 500 µm = 0.5 mm
I haven't measured Platine, but 5 should be correct.
