I have had many moments of frustration over an issue that some of you may have experienced with digital printing. The 'fogging' of the inside of the glass of a framed piece. Have you ever framed a digital piece, only to have to remove the matted image and clean off the glass - again? That is the result of an improperly dried digital print. I knew the images needed time to dry and I usually allow them to dry flat for a couple of days, but apparently sometimes that's not long enough. Or it might be long enough if you put a piece of paper over the image to help absorb the moisture that emits from the drying image. This is called an out-gassing fog from the glycol (a wetting agent that is used in all ink jet inks) and more specifically affects the RC photo ink jet papers Even though the fast-drying micro-porous papers like Epson's 'Premium' line, there is still water and glycol under its super-absorbent coating trapped inside. (I'm quoting some of this from a search I performed on the internet from Inkjetart.com).
On occasion I have been known not to always lay a piece of paper on top of the newly printed image, so now that I know the 'why' I will be more careful. Just an FYI for those who have had this issue. That's your small lesson for the day!
