gum printing ratios
Hello all, Thanks for all the help you've given so far--I've been working for 3 weeks and have made 2 successful prints. I've been doing lots of testing and in discussion with another gum printer [that my first prints worked and the latest ones are not] I was telling her that I thought I was getting a handle on the process when we got into a little disagreement. So here is the question for everyone: when altering the ratio of gum to pigment, do most people add a little more gum to get less pigment. And if so, should the dichromate amount be equal to the total amount of those two? My friend said that I should always use the exact same stock [which I have mixed at 1:2 pigment to gum--from there I have been adding pigment or gum depending] and alter the amount of dichromate? Her way did not work. I finally understand what each part of the equation will do to my print--but I'm having trouble deciding which variable should remain constant. Maybe it's hard without seeing my prints...
