Neil, Some papers are more susceptible than others to what we've generally
called "plating out" -- we used to think it was Strathmore this or the
other that. But I have NEVER seen it when there was no heat drying.
And any forced heat drying is likely to bring it on.
Once we realized that heat drying was flattening the print range and
stopped, presto -- no more plating out.
