I recently printed a batch of Ilfochrome prints in their P30 chemistry using a Jobo CPP2 with an 8x10 print drum. I followed the Jobo and Ilford instructions and used fresh chemistry and paper.

However the backs of the prints just look awful: Serious staining, brown, yellowing, and sometimes even green stains are evident. The level of stains looks really pathetic. The entire backs of the prints are yellow stained!

Anyone else have this experience? Is this typical of Cibachrome prints in general? Will this staining affect print longevity? Correct me if I'm wrong, but is this due to the fact that the backs of prints in the jobo drums (due to the ridges) do not get adequate exposure to freely flowing chemistry?

I was thinking of eventually getting a Fujimoto type roller-transport processor for color work, but I wonder if any one with experience with roller-transport type processors can tell me if they observed Cibachrome print stains on the back of those prints too?

Thank you in advance for any input.
