I think it can not be the papers since I have tried quite a number of
papers that are recommended by other salt printers and they all show
the stain. I and beginning to think that the problem is in the
salting emulsion, and must be either the sodium citrate or the
ammonium chloride, or the two in combination. For my next tests I am
going to switch to sodium chloride and leave out the sodium citrate.

It has been pretty warm and humid here in SC over the past several
weeks, but I never know this when inside my house because we are air
conditioned 100% of the time, and the conditions are a constant 70F
and 55-60% relative humidity.

Usually very smooth.
