Daniela,
I can't help you with your question as I am not Roy, but I am curious 
as to what sort of papers you are using. I started my artistic life as 
a painter. I am interested in using uncoated papers, mostly watercolor 
papers such as Arches and Fabriano. I would like to know a bit  about 
the pitfalls of using such papers (other than what you mentioned) 
before I commit a large amount of paper and ink to the task. Would 
appreciate any thoughts. Molto grazie.

Brian
