RE: PVA size (probably major setback)

That's not a nice! Are you sure your exposure and development times are OK?
If they're OK, then what you experience indicates a weak mechanical bond
betweem the hardened gum layer and the sizing/paper...

the exposed gum is very vulnerable, when wet, on the caparol size. i tried
it again on the two test strips i posted earlier. when dry it is very robust
and can hardly be scratched off, but as soon there is water, it changes. i
re-wetted a corner of the test strips and used the brush a little.it went
right off. the emulsion adheres better on 1+5 size, than on the 1+1.
