I am testing a soft ground mixture that consists of 3 parts Graphic Chemical Water based Block Printing Ink Peacock Blue, 2 parts Golden Acrylic Silkscreen Medium, and 1/2 part Golden GAC 200. I am using newsprint as the transfer paper and a #2 pencil for drawing.
Date: July 1, 2009
Researcher’s Name: Mark Zunino’s soft ground workshop students
Plate Material: .032 Copper
Plate Size: 6 in x 7 in
I degreased the plate with Bon-Ami and water made into a paste. The paste was rubbed across the plate surface and rinsed away with water. The copper plate was blow dried and finished with a clean towel. I rolled a thin amount of ground across the plate’s surface just enough so that you could not see the copper sparkle through the ground. I used a variety of drawing utensils including a pen, pencil, and my fingers for tone. I dried the ground on the hot plate and etched the plate for 5 minutes. I printed a proof and subsequently scraped and burnished away any unwanted areas. I degreased and reground the plate and completed more drawing. I hardened the ground again and etched for another 10 minutes. I applied an aquatint and stopped out with a lithographic crayon in several areas. I etched the plate for 2 minutes and printed another proof.
The plate was etched in a vertical etching tank filled with 35° Baume Ferric Chloride.
Timed Application of Mordant
Removal of Grounds
The ground was removed using a stripper bath of Arm & Hammer Washing Soda and water (100 grams/1 liter). I rinsed the plate under warm water after soaking it in the stripper bath for 10 minutes.
After Bath Evaluation
The ground held onto the plate well.
I used Daniel Smith Creamy French Black etching ink. The ink was carded on with a orange plastic scraper, wiped with used tarlatan, and hand wiped.
