I made a search and, unless I didn't make it right, there is no posts about "flat print", so I decided to post this.
I have a recurrent problem to get a "flat print" out of fiber base papers. The question is: there is a way to get a really flat print?
I received a nice print as a present of a friend, really flat. I asked her how she could produce such a nice flat print and answered me that she didn't made it, she ordered to a professional lab.
