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. Instead of using newsprint I am going to use a coated parchment paper called erasable bond as the transfer paper.

Researcher’s Name: Amelia Vottero
Plate Material: .032 Copper
Plate Size: 4 in x 3 in
Room Temperature: 76°
I degreased the plates with Bon-Ami and water made into a paste. The paste was rubbed into 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 ink across the plate’s surface just enough so that you could not see the copper sparkle through the ground. It was easier to roll the ground than in the previous test. I let the plate sit for 10 minutes and drew with the erasable bond and a #2 hard pencil. My drawing time lasted 50 minutes. The marks translated just as well in the end of the process as the beginning. I heated the ground on the hot plate to dry the ground before etching.
The plate was etched in a vertical etching tank filled with 35° Baume Ferric Chloride.
Timed Application of Mordant
20 Minutes/Rinse/10 Minutes/Rinse/15 minutes/Rinse
Removal of Grounds
The grounds were removed using a stripper bath of Arm & Hammer Washing Soda and water (100 grams/1 liter). After soaking the plate in the stripper bath for 10 minutes we rinsed the plate under warm water.
After Bath Evaluation
Etched marks are visible on the plate but the plate appears to have picked up the texture of the paper.
The plate was inked with unmodified Graphic Chemical Bone Black and 50% Graphic Chemical Stiff Black. The ink was carded on with a orange plastic scraper, wiped with used tarlatan, and hand wiped.
Paper Type: Hahnemule Copperplate
Paper Soaking Time: 15 Minutes
Press Blanket Setup: Small Takach, 2 Blankets, 8.0 pressure
The plate picked up background noise from the paper. There is false biting and an overall hazy quality to the print.
