I apologize for not answering sooner but I been off working. RC paper has had problems in the past. Critin (sp?) did some research several years ago with RC paper that was framed and matted and hanging on the wall. The jest of the article was that the RC paper started to show signs of coming apart. I don't remember the exact phrase and wording but it had something to do with "out gassing". Kodak says they have fixed the problem. That may be, but twice bitten is not something I look forward to. Besides the fiber based paper looks so much better to me. The glossy is too shiny and the mat is too mat. I have been using fiber for many years (over 30) and I am used to all the problems using fiber causes. To me, it is worth it. Your mileage may differ.

As color work goes, I have professionally printed color work that is about 20 years old and it is almost all cyan now. It is fading big time.
