I abandoned the idea of using an aquatint in combination with Lascaux Wash Resist. The aquatint covers up everything that I applied to the plate. In this experiment I used a Lascaux 2094 Wash Resist without an aqautint. Instead I painted Lascaux 2092 Stop-out resist over all areas of the plate that were left exposed to prevent open-biting.

Researcher’s Name: Maya M. Bajak
Plate Material: .032 Copper
Plate Size: 5 in x 5 in
Room Temperature: 72° Snowing
The plate was degreased with Bon Ami and water. I painted Lascaux 2092 Stop-out resist on the edges of the plate and applied Lascaux 2094 Wash resist in the middle of the plate and diluted it with water for easy reticulation. I air dried the copper plate 10 minutes then placed it in the drying box for 20 minutes. Between the stop-out and wash resist no part of the plate was left open to false bite.
The plate was etched in a vertical etching tank of Ferric Chloride at 37° Baume
Timed Application of Mordant
Removal of Grounds
The grounds were removed with Lascaux 2098 Concentrated multi-purpose cleaner and a nail scrubber.
After Bath Evaluation
There is visible reticulation on the plate from the wash ground.
Unmodified Graphic Chemical & Ink Co. Bone Black #514 Etching Ink. The ink was carded onto the copper plate with mat board scraps and wiped with used tarlatan.
Paper Type: Hahnemuhle Copperplate
Paper Soaking Time: 20 Minutes
Press Blanket Setup: Small Takach, 2 Blankets, 8.5 pressure
The plate prints excellent without need for an aquatint. It is important that every area of the plate is either covered with wash ground or stop-out solution to prevent open biting.
