Soft Ground with Water-Soluble Ink and Acrylic Mediums Test 4

Test Summary
This test was designed to emulate a traditional soft ground drawing using a water-based ground instead of an asphaltum/wax soft ground.

Date: May 22, 2002
Researcher’s Name: Vanessa Lang
Plate Material: .032 Copper
Plate Size: 3 in x 7 in

Plate Preparation
I degreased the plate with Bon Ami and water made into a paste. I built up several thin layers of Graphic Chemical water-based block printing ink #1659 using a small Speedball roller. I rolled in opposing directions in order to get the maximum amount of coverage. I used newsprint as the transfer paper and a sharp pencil for drawing. I laid the transfer paper over the wet ground and drew into it with a pencil. I tried different ways of translating marks. The most successful method appears to be repeatedly going over the same lines to lift the ground from the plate. Single drawn lines do not transfer.

Etching Notes
The plate was etched in a vertical etching tank filled with 42° Baume Ferric Chloride.

Timed Application of Mordant
45 Minutes

Removal of Grounds
I used Bon Ami and water made into a paste and lightly scrubbed away the ground with a nail brush.

After Bath Evaluation
The lines etched light with no real differentiation in density or thickness.

Inking Methods
Graphic Chemical Perfection Palette Black with no modifiers scraped onto the copper plate with mat-board, wiped with tarletan and finished wiped with phone book paper.

Paper Type: Hahnemuhle Copperplate
Paper Soaking Time: 30 Seconds
Press Blanket Setup: Large Takach, 2 Blankets

Test Conclusion
The lines are faintly etched and there is no tonal distinctions.
