color printing
Ronald Fagan
is that I am regularly getting streaking at the top of the print,in the
sky area,especially with a deep blue sky. I have tried all sorts of
variations of time and temp.Does anyone have any suggestions that would
help me eliminate this problem. I am using a JOBO cpe processor. Thanks,
Ron

: I am now printing 8 x 11 RA4 prints on supra N surface paper. My problem
make sure the tank is level, or you may not be getting sufficient chemical
coverage. Also make sure the beach time is long enough. I actually have
to go about 2 min longer than charted time on the bleach to full clear
the photo. Note, I'm using R3000 (reversal process) but I think the
problems can be simular.

we use an ra-4 processor with 3 baths and had a stop between dev and
bleach/fix. Kodak recommended that we not do that but make the third bath
water. worked either way for us but YMMV.

no 'benefit', just the way it was 'done' when we'd used the old system
with EP-2.
the system now dev -> bleach/fix -> water gives a 45 sec wash before
going into the wash which is usefull in that it rinses the bleach/fix off
of the print before it falls into the water.

If you don't use a stop with RA-4, or at least two good rinses, you're
likely to get magenta stains.
If you're getting magenta stains on the borders, then your drum is
probably trapping developer between the print and drum that's coming
out during bleach/fix. Developer contamination of bleach/fix will
cause magenta stains. That's why the stop or two good rinses prevents
it. I used to get inconsistent magenta staining with the Bessler 8x10
drum sometimes even with 2-3 good rinses because if the way the paper
would lay in the drum. The stop and rinse mostly solved it. Never
had the problem in the Jobo drums (1526, and 2800 series drums) with
either two rinses or a stop/rinse.
