Re: chalky prints
Could it be bronzing due overexposure? I noticed that when you overexpose
Ferric processes, you get some kind of solarization. (That's also true
when you use less than ideal solution -> usually, a thicker coating
requires more exposure and when it's too thin it's automatically
overexposed - so, finding the correct amnt. is crucial.)
Also, (less likely, but will mention anyway) papers with weak sizing will
exhibit some loss of contrast because sensitizer will penetrate the paper
too deeply and the image will form inside of paper instead of sitting on
top of them. Using an additional sizing layer and/or less surfactant - if
you include it in your workflow - could help if the problem lays there.
