RA4 Printing. Blue cast in dark areas.

    I have been printing on Fuji CA using Fotospeed CKRA4 dev and blix - no stop
    solution as recommended by Fuji. Timings and temp. as required by
    Fotospeed's instructions.
    I use a Nova slot procesor.
    Some pictures have a very definite blue cast in dark areas. Highlights are
    fine.
    Troubleshooting guide suggests blue cast is a result of too low temp. But
    not all pictures affected. And I tried tweaking the temp/ up a bit with no
    noticeable change.
    Can anyone come up with advice. Maybe someone has had this problem and
    solved it. Any help gratefully received.
    Thanks
    Jeff

    Willie--

    I had a similar problem with Kodak Ultra IIIRC and the standard Kodak RA-4
    outfit. Oddly enough, it turned out that *high* temperatures were the
    problem, not *low*. I was running the process at 96F, and the blue blacks
    went away when I went back to using 94F.

    I run my process hotter than 96 degrees using Kodak Supra paper without
    problem. I will have to check to see if I have any Ultra to compare.
