Is there any perceptable difference between either color
prints or B/W prints made on Epson Premium Glossy Photo Paper(250) (e.g 24 inch
rolls) vs the cut sheets (e.g. 8 1/2 x 11 inches) using K3 inks?

I've been testing the cut sheets on my 7800 and I am considering
purchasing a roll of Epson Premium Glossy(250).

Any difference in weight, brightness, surface texture, scratch resistance, gloss, etc. would be of interest. (I would of course use the appropriate profiles for each
paper (roll vs cut sheets). I am considering using the smaller cut
sheets as proof sheets rather than cutting down and uncurling the roll
paper to make proof sheets.

Thanks,
Ken

Just got through comparing a B/W image printed on both the roll(250) and cut sheet versions. I am unable to detect any differences.
