I must say I have been underwhelmed by the Arches Aquarelle with the Kallitypes and the Saltprints.
You mention an acid presoak, and I assume that the size or paper base is alkaline. If so , would that have an impact on the cyanotypes as well.
I will try a 3% citric acid pre-soak (I have a lot made up) and see if it makes a difference.
I have read your kallitype article many times and will try the sodium citrate when I can get hold of it.
Thanks to all for the comments
