Recently I have found that some of my prints are exhibiting a cracking
on the surface. The cracking appears as horizontal cracks on the surface
of the print. It looks a little dried paint that has cracked with age, or
heat. No emulsion is flaking off, but the cracks have a definite pattern.
Could this be caused by too much pigment concentration? This strikes me
as the most likely explanation, though I have other prints using the same
pigments, and coated and exposed at the same time that don't exhibit the
same problem.
I was re-examining the affected prints the other evening and it seems it
has only happened to a stock of older paper I had, which had proably been
sized 2-3 years previously. Could this be the heart of the problem? All
the affected prints are on Bockingford paper.
Is there anything else I haven't thought of that may be contributing to
this problem?
Cheers
