Re: tricolor gum question - yellow
Cut your pigment in half. With some yellows, I may even dilute 1+30! Don't have my calculations in front of me but I know PY150 is a strong yellow and needs quite a bit of dilution. Never have used cad yellow tho I like its color..because I don't do yellow as a first coat ever because it's hard to eyeball registration with it. chris ----- Original Message ----- From: Paul Viapiano <viapiano@pacbell.net> To: alt-photo-process-l@usask.ca Subject: Re: tricolor gum question - yellow Date: Tue, 17 Nov 2009 14:56:53 -0800 >Thanks, Jim... > >I bought a tube of Naples Yellow a few weeks ago and just >used it as a first layer of a monochrome print.
