Re: muddy gum print--help?

[Paul Viapiano <viapiano@pacbell.net>]

Charles,

The person who Jim refers to as using the 1:1 dilution of Gamblin PVA Size 
uses several coats at that dilution, letting it dry for a few minutes btw 
each coat. He uses the Gamblin because he has had a double lung transplant! 
He gets beautiful results...

Supposedly, the undiluted Gamblin will give a slight sheen to the print, 
while the 1:1 dilution will be more matte...

I have a bottle and haven't used it yet, mainly because I haven't started 
printing gums or gum-overs...yet...yet...;-)

Paul
