Another aspect of my experimentation during PrintFest was control over the toning characteristics of reused gold toner. Straight gold toner (gold chloride and citric acid) form a good, but not great, toner that can tone prints purple if used in sufficient concentration. Lower concentrations tend toward a cold black. But the toner has a short shelf life once mixed, and really only functions as one-shot; I hate doing that with a $50 bottle of gold chloride that will only tone about 20 prints – $2.50 per print – palladium, which tones substantially nicer, is only $7.50 a print. Denser blacks with palladium. Very pleasant. Well worth the expense.<\/p>\n

But gold toner #2 uses thiourea and tartaric acid instead of citric. Its blacks are almost as nice as platinum. And, best of all, this formulation has a long shelf life and reuses well. I’ve stretched up to 9 prints out of 500mL of toner. I’d like to continue doing this, but needed to better understand the color that comes out of this toner over its lifespan.<\/p>\n

This print is toned using fresh gold toner #2. Some more coming up will show off a little bit of how that changes over its life.<\/p>\n","protected":false},"excerpt":{"rendered":"
