Re: Safe methods for washing gum prints
One per tray is the old rule for development. I question whether any further washing is of any value. If I am pressed by to many prints exposed to fit the available trays I will develop back to back and turn them over now and then. Mounting them on a rigid substrate would be a great asset in developing, it would be possible to develop many print in a vertical tank if the tank was set up with grooves in the sides to separate the prints. Printmakers are now using tanks like this to etch copper plates. They also use aquarium bubblers to move the sediment out of the etching lines. Could it be possible to set up a system of bubbles so even that it could aid developing? As far as washing gum prints I will admit that I like using old water over and over again to trap the chromate and to prevent air bells forming under the print. I have a stack of trays that I keep water in and unstack to reuse each time I print. This week was the first time perhaps 20 sessions of printing where I used clean water. Amazingly the prints that are on sized paper wash clean in dirty water. The edges and backs will be stained by the water. Most photographers would cringe at any of this but it can be done... So, I don't think washing a print beyond development is significant in look or longevity.
