Abstract: Finding a replacement for solvents used in monotype to create fluid textures, reticulated tones, and marks. This test is testing the reaction Envirostrip has on the ink and if it will react in a similar way to a solvent, like mineral spirits. We decided to try Envirostrip because it uses enzymes to break down emulsion in silkscreen and thought the active natural enzymes may react positively to breaking down the ink.
To begin, I washed the plate with soapy water and dried it. Then I added a little #00 plate oil to the Graphic Chemical 514 Bone Black oil-based ink and rolled it onto the plate evenly with a brayer, as normal. I applied the concentrated Envirostrip using a spray bottle and allowed it to sit for 10 minutes of the plate. After the plate sat with the solution on top of it, I blow dried it until it was completely dry. The plate did not show the reaction we are looking for.
Soaking Time: 15 minutes
Press: 2 sizing catchers, Takach etching press at 7.5
Some ink was pulled off by the envirostrip, but the areas where the Envirostrip sat on the plate longest pulled off the most ink, particularly the outline of the puddle.
