Proper clearing procedure should clear completely whether or not the
print is developed fully. Undeveloped or unexposed coating materials
must be removed (cleared) from the print. The choice of clearing agent
and times may relate to the materials and previous processing used and
should be tested for those conditions.
What John is referring to may be fogging, not a lack of clearing.
Fogging and lack of clearing are two completely different things, even
though they may both show as density in the print. More likely, John
has not chosen an effective clearing agent. Remember that a change in
developer, as a change in paper or coating chemistry, may make the
process become more compatable with another clearing agent. One should
also test their clearing procedure carefully as some lack of clearing
may be hard to detect without a test and using the indicator (see my
guide for details on clearing testing with an indicator).
