I am planning to do some printing in a remote part of Australia where I will have some access to a rainwater tank, but will have to use far less for Fibre print washing than I'm used to. I was planning to use a series of trays, with one print per tray and transfer the water from tray to tray such that the least-rinsed print would first be washed in the most-used water and so forth. I was planning to use a sulphite/bisulphite washing aid (Richard K recommendation) prior to the many water rinses. Sodium bicarbonate is quite cheap. Would you advise using a little in each lot of water? And if so, how much. And would you advise using none in the last one (or several) rinses?
