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 three 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
I degreased the plate three times with Bon Ami and water made into a paste and towel dried. I applied Z-Acryl Stop Out Solution over areas of the plate that I wanted to remain untouched by the Ferric Chloride. I let the stop out air dry for 10 minutes and applied 9 passes of very fine aquatint to the plate with a standard Paasche airbrush. The aquatint was allowed to dry for 25 minutes in the hotbox. The copper plate was then etched for 10 minutes.
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). The stop out solution proved difficult to remove and required a long period in the stripper bath.
After Bath Evaluation
The etch was successful.
The plate 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 aquatint translated well.
