Question

• A. Spirit
• B. Benzene
• C. Nitric acid
• D. Gum Arabic

Hint:

Nitric acid is used for etching plates.

Answer 1

The Correct Option is C

Nitric acid is used in intaglio printmaking to etch metal plates. It reacts with the exposed areas of the plate, corroding the surface to create grooves and lines that hold ink.

• Etching process: The acid corrodes the exposed areas to create grooves that hold ink.
• Control factors: The strength of the acid and the duration of exposure determine the depth of the etching.
• Artistic effect: Allows for varying levels of detail and tonal effects.
• Safety precautions: Proper measures, such as wearing gloves and working in a ventilated area, are essential when handling nitric acid.
