Hello Sandy, my kalli developer experience is similar. I can't reuse the
developer too much or I get staining. I'm working quite large and my
usual procedure is less "measured" that yours. I simply throw out 1/2 of
the developer each session and replace it with fresh mixed developer the
next session. It should be noted that about 1/2 of my Kalli printing is
onto cotton fabric (rather than paper) and that may be a factor. I keep
my platinum developer going almost indefinately, only replacing what is
carried out.
