Jobo processing question

Discussion in 'Darkroom Developing and Printing' started by Ed Margiewicz, Aug 26, 2003.

  1. I just started getting some dark spots on some of the ilfochrome prints I
    make in my jobo cpa. These spots look like they are drops that are
    splashed on and probably from the solution(s) I use. It doesn't happen all
    the time and never in the past. I have been printing iflochromes for a many
    years. After each print I use compress air to dry the area of the lift that
    connects to the drum to minimize and water/wetness when connecting the drum
    for the next print. Has anyone experienced this and have and possible
    explanations and/or solutions.
    Thanks

  2. Sheer speculation: I had weird marks on my EP-2 and RA-4 prints and a
    one-minute pre-wash with developer-temperature water solved the problem.
    Perhaps give it a try.

    It does sound like contamination. I had a similar problem for a while. I
    did two things to cure it. First, I made sure the drum was thoroughly
    washed after each print. The easy way to do this is to wash the print in
    the drum. The two minute wash Ilford recommends is a bit optimistic. I
    use six changes of hot water with about 45 seconds per rinse. I still had
    some occassional spots and irregularities. I traced these to residual
    water in the drum at the start of processing. The cure is a quick wipe of
    the inside of the drum with a paper towel to pick up any drops and puddles.
