Re: My own PVA glue sizing experience (attn: marek + the gum woesagain)

marek,
that is a very nice color indeed.
you don't need to do this while coating a new layer and risk ruining  a 
fine print, just take a corner of a discarded print or test strip (maybe 
an aera which got a lot of exposure), put a drop of water on it  and 
scrub a little with a brush. with my pva size the gum will come right 
off, even when properly exposed or overexposed. it doesn't dry 
waterproof, like it should, that's why i can't put on another layer 
without damaging the on beneath.
my paper has a very smooth surface. definitely not spongy. and yes, i 
preshrink.
