Re: oil printing
I found them appealing, but resisted for a number of reasons, including and especially because I'm allergic to the solvents (and warn anyone using oil paints be careful: Turpentine is one of the two most allergenic substances for humans. The other is chrome, tho I don't know if that extends to all forms, including dichromates, or just shiny bumpers.)Only a pea-size dot of ink is needed for oil or bromoil printing, and I am not sure there is turpentine in the (modern) ink composition. Is it too much for your allergy?
I wash my brushes with shampoo (first concentrated, then diluting with some water) and only from time to time I need to give them a solvent rinse.
