Some thoughts and suggestions for safer lithography
by Pablo Delfini
I replace nitric acid in lithography on stone, marble, and aluminum. I use lemon juice or citric acid mixed with gum arabic in varying concentrations.
It is a very eco-friendly alternative that works very well. For the various processes of removing greasy drawing materials, I use vegetable oil—the same oil I use to clean rollers, spatulas, glass surfaces, and so on.
In waterless lithography, dissolving the silicone presents a challenge. An “eco-friendly thinner” sold in Argentina works very well for this purpose.
The best and most user-friendly option is an Italian thinner that Fabiola Mercandetti and I tested during a workshop in Rome.
For waterless lithography, it is best to draw using only water-based materials, avoiding those that dissolve in acetone.
Another new development is the method for cleaning waterless lithography plates after printing: using vegetable oil followed by soap and water.
Waterless lithography on Tetra Pak is an alternative option that allows for short print runs. I was recently able to improve upon this process by adapting the technique of Japanese artist Motomi Sunoda, who works with waterless lithography on paper using a shellac base. I adapted this method for thin recycled cardboard and Tetra Pak, and it works very well. I use an ink I make from instant coffee, which is the best drawing medium for these Tetra Pak and thin cardboard plates
For polyester lithography, I use the *frottage* technique with standard school wax crayons and with handmade crayons created by Mariel Bichi, an Argentine artist specializing in non-toxic printmaking. *Frottage* on polyester, works very well with wax crayons.
I also use toner washes on the polyester, fixed with nail polish remover as an alternative to heat.
Additionally, I have experimented with handmade toner crayons by Mónica Vidal—another Argentine non toxic artist—testing them on stone and marble; when fixed with acetone-free nail polish remover, they yield interesting results.
