A couple of questions for any of you who have used a Ganz easel. Does it really keep fiber paper flat? Or, I guess what I want to know is, does it keep fiber paper really flat, not just almost flat? I say that because my fiber paper is often somewhat stubbornly curled, typically with the edges wanting to curl up higher than the middle, and I am going through a lot of trouble to focus carefully, align my enlarger, etc., so it is important to me to have the paper flat. Secondly, does the surface of the paper get damaged in the process of sliding it into a Ganz easel? I know that the Ganz easles are a single size, but are there any other significant limitations that I should be aware of?
