Materials: 6″x9″ PETG plate, Graphic Chemical Bone Black Ink, #00 plate oil
Abstract: Finding a replacement for solvents used in monotype to create fluid textures, reticulated tones and marks. This test is to see if plate oil will manipulate or break down oil based ink.
I cleaned the plate with soapy water and dried. Then I buffed the surface with gum arabic. Taking a damp piece of cheesecloth, I wetted small sections of the buffed plate then buffed it dry with another piece of cheesecloth, moving my way across the entire plate until it was all buffed dry. This created a very thin barrier of gum arabic for the ink to rest on. The plate was then rolled with ink. I poured a quarter sized amount of #00 plate oil directly onto the plate and moved it around a little bit. The plate was left alone for about five minutes then I moved it some more, let sit again for about five minutes then moved it again. Then I used a blow dryer to move the plate oil with some heat. I could see areas where the ink had moved a little.
Then I blotted the plate oil with newsprint three times before printing.
Inking: Graphic Chemical Bone Black, brayer to apply to plate
Soaking time: 20 minutes
Press: 2 sizing catchers, takach press at 7.5
The plate oil did remove and move around some of the ink. The longer it stayed in a particular spot, the more ink was removed.
