    Let me add the caveat that my processing times (soaking in water) for gum printing are less than 15 minutes—most times, less than 10. If you need to soak for longer time, then preshrinking might be needed.

    FWIW

    I'm getting a show ready - 12 big prints. 4 Layers + each.

    I have room to develop 4 at a time.
    I'm working 4 days - so I have Fridays and the weekend to print.

    Preparing the paper (pre-shrinking and mounting to a board - Fabriano Artistico EW) 1/2 a day. Dries overnight.
    Next day - 2 hours to do a 1 shot gelatin + hardener brush size
    I do these in big batches as it is a pain.

    Printing :
    Thursday night 6pm - Yellow Layer - Dries in 30 minutes.
    8 mins exposure, 2 hours development. Dries overnight. Home at 10pm.

    Friday Morning - Magenta Layer - 3 hours. Left to dry overnight again.
    step/repeat for Saturday and Sunday.

    Only way I can get complete prints done without leaving half complete prints for a week...

    Very slow process. But strangely addictive.
