Re: Gum Calibration 2 (How to read color samples?)
David, could it be that the pigment concentration is too much? I think the problem lays right there. In an article by Sam Wang it was written that he mixes his color to a saturation and luminosity close to the test patches found in color newspaper (usually printed somewhere in the bottom or in the middle of two pages). And I remember Katharine writing something about this too... Regards, Loris. P.S. Going to mix a new batch of gum (from powder) that will be used to make stock solutions... I will start with: 1+3 PY151 (15ml paint giving total 60ml stock) 1+5 PV19 Rose (15ml paint -> 90ml stock) 1+7 PB15:3 (15ml paint -> 120ml stock) and dilute more as necessary. 24 Ekim 2008, Cuma, 9:06 pm tarihinde, davidhatton@totalise.co.uk yazmış: > > > Hi Loris, > Your idea sounds good, however it doesn't fit with the instructions > which come with the product and I haven't tried it.
