Britt, Rosemary and Clara, thanks for your interest. Actually, I am scanning a lot of line drawings for a book, some are mine, some aren't. Some were drawn on Bristol paper, some on acetate or a kind of paper like the one architects use (I don't know the english name for it, but it's tricky to scan it), some are photocopies... Some of them have very thin, weak lines and/or stipples, that get easily lost during the scanning process, especially if the paper doesn't make a good contrast . I've been experimenting and I think the results are better now, but I still want to learn about the way to treat such difficult originals right from the scanning process. I use a Sharp JX-330 scanner and I'm looking for its web site. I will also try to get the book. Silvia.
