Room Temperature: 65 degrees F
Humidity: low /dry
Materials: 5 1/4″x9″ aluminum plate, Akua Mars Black Ink, boiling water, citric acid powder
Abstract: Finding a replacement for solvents used in monotype to create fluid textures, reticulated tones, and marks. This test is testing the reaction that hot citric acid will have on the ink and if it will react in a similar way to a solvent, like mineral spirits.
Citric Acid Hot Water Mixture:
1 cup boiling water
7 tbsp citric acid powder
Dissolved thoroughly and poured into a spray bottle.
I cleaned the aluminum plate with soapy water, dried the plate, then rolled Akua Mars Black ink onto the plate with a brayer until it was evenly coated. I sprayed the citric acid/water mixture onto the plate and let it sit for one minute then placed it on the hot plate until it was fully dry.
Paper type: Arnham
Soaking time: N/A
Ink: Akua Mars Black rolled on with a brayer
Press: Brand etching press with 2 sizing catchers
The citric acid formed a gel-like substance when it dried on the plate. It reacted a little like a resist in some areas because a lot of information was still left on the plate after it was printed.
