ABSTRACT:
A method of drying processed polyethylene coated photographic paper in an enclosed drying chamber through which the exposed and processed polyethylene coated photographic paper bearing an image on one side of its sides is made to travel.
This comprises directing radiant heat onto the non-image bearing side only of the paper as it travels through the drying chamber and as a stream of air flows over the image bearing side of the photographic paper.
The advantage of this invention over drying apparatus at present commercially available is that less heat energy is required to dry large photographic sheets.
