Hello,
Believe it or not, I just realized that papers had different weights depending on wether they are in rolls or sheets. For instance, why is it that Ultrasmooth Fine Art is much lighter when it comes in a roll ? This is quite a disappointment to me since until now, I loved this paper partly because of its heavy feel (325g/sqm). I'm more comfortable working with heavy papers because I believe paper weight has an important impact on the way a customer evaluates the quality of the print.
I'd like to know the reasons behind these weight differences. Any ideas ?
