[alt-photo] Re: back to the flaking/speckling question

[Diana Bloomfield]

Hi Cor,

No, I don't preshrink.  I've managed to make an image as big as about  
16x16 without having any registration problems.  I've been able to do  
that only with this particular paper, though.  I'm not sure why this  
paper is so different from their other papers.  And because there's so  
much sizing in it, I coat the first layer without any sizing.  And  
then before I put on the other layers, I do add that one thin coat of  
PVA, and that one coat seems to work fine for multiple layers.  I  
never have to apply any additional.

Diana
