Is it OK to flatten fiber paper a week after it has been dried? I use a public darkroom (local college) to print on fiber paper then come back the next day to flatten the paper using a hot press (?). I am getting busy at work and can no longer go to the darkroom twice a week. I am thinking I can print one day, then come back next week to print and flatten. I understand RC paper is an option and I like Ilford's pearl. However, I am concerned about archival properties as I want to keep my prints for at least another 40 years Thanks much for any information you can send my way.
