I need some help with cooking up some ink. Please PM me if you have any advice for me. It will be greatly appreciated. I work at a sign shop and run a solvent printer. I collect all of the waste and have gallons of ink stored at my workplace. The waste is a dark blue almost black from a combination of Cyan Magenta Yellow and Black inks. I was wondering what the best method of cooking the inks would be. What the best additives to turn it thicker and darker black, and the best techniques to go about this to turn my solvent ink waste into some super boku permanent slick ink would be.
