Using a combination of Edinburgh lift ground, Z-Acryl hard ground emulsion, and airbrushed aquatint this test will be an artistic exploration of the processes discovered in previous tests. The following test is part one of four parts of plate development.
Date: December 1, 2009
Researcher’s Name: Megan Klazura
Plate Material: .032 Copper
Plate Size: 5 in x 6 in
Room Temperature: 71° Clear, Cold, Winter Day
Degreased plate with Bon Ami and water made into a paste and towel dried. I applied Z-Acryl hard ground emulsions with a foam brush. Air dried for 5 minutes and then placed the copper plate in the hotbox for 25 minutes. Completed a drawing with an etching scribe under 10 minutes and etched the plate for 20 minutes in a bath of Ferric Chloride.
The plate was etched in a vertical etching tank of Ferric Chloride at 36° Baume.
Timed Application of Mordant
Removal of Grounds
The grounds were removed using a stripper bath of Arm & Hammer Washing Soda and water (100 grams/1 liter).
After Bath Evaluation
The etch was successful.
The plates was inked with unmodified Graphic Chemical & Ink Co. Bone Black Etching Ink #514. The ink was carded onto the copper plate with mat board scraps and wiped with used tarlatan.
Paper Type: Magnani Pescia
Paper Soaking Time: 20 Minutes
Press Blanket Setup: Sizing Catcher and Pusher, 8.5 pressure, Small Takach Etching Press
The hardground lines etched perfectly.
