I never have.
What kind? Isopropel, Denatured, etc??
I have bottles of absolute alcohol and propanol which with experience I find i
very rarely use.
>In Gum printing is a solution in the 20-33% typical? The formulas I've

I use saturated solutions. 11% for potassium and 33 % for ammomium. But for
carbon and oil and so on I use 4% and 3% respectively.
>Does the higher percentage solution effect contrast as well?
The weaker the solution the higher the contrast.
Hope this helps.
Perhaps you have already noticed from the list that you are in the midst of
other 'alt' persons.
