A new alternative printing process: The Tannintype

[UrabobPrinting]

I was playing around with toning cyanotypes when I realised that my Potassium ferricyanide solution had gone bad so I experimented around with just Ferric Ammonium Citrate and tannic acid solution I made by boiling leaves and tea in water. For my first test, I coated paper with FAC solution (1g/10ml water) dried it, exposed it then put it in a bath of the tannic acid. Unfortunately, no image formed. So, I exposed it again after dry and was amazed to find that an Image had formed with good sepia tones and you just develop in water (not too long).

I call this process the Tanintype.

I have yet to make a proper print but, I will try by mixing teh fac and tannic acid together then coating and I will make my tannic acid solution stronger.

Looking forward to your results!

Sounds interesting! Will look forward to seeing a print.

BTW have you checked this?

Direct tannin process (no bleaching, no Potassium ferricyanide, just ferric oxalate/water and hydrogen peroxide + tannins)

Hi everybody, I want to share a new process, which involves direct "iron gall ink" print without the bleaching of cyanotype etc. Short process description: 1. Sensitize suitable paper with ferric oxalate [only ferric oxalate, nothing else...] 2. Expose the paper under negative and UV light...
