I've been making color prints at home for some time and am quite satisfied with it, but there is one problem that I've not been able to solve as yet. The white margins (hidden below the masking frame) are not as white as they should be. It' not due so some stray light, I tried to process a piece of paper right out of the box, without any exposure, in total darkness, with the same result. I was using the Tetenal RA4 chemistry for room temperature before, now I'm using the Tetenal professional kit for higher temperature (35 deg C), but it has not helped. The papers I use are Kodak Supra Endura. It seems to me that it gets worse as the working solutions are close to capacity, but it is noticable right after preparing the solutions as well. It's not totally bad, if the print is viewed against a dark background, it doesn't matter, but when placing it against the back of another print, the slight chamois hue is clearly seen. In any case, prints from a minilab are brighter (made on Kodak Royal). Can it be due to chemistry or paper used? Has anyone a similar experience? I know two or three people here who have reported the same problem.
