Artists' window tests where prints are taped to a window have a lot of infrared (IR) energy exposure that doesn't occur at locations further into the interior of the building. I have measured print surface temperatures as high as 54 degrees centigrade (130 deg. F) under those conditions so desiccation is still very strong even though the print is indoors.
