Intaglio Acid EtchingPress Guild

Calculate plate etching duration in nitric acid or ferric chloride based on metal type and Baumé strength.

Workshop Parameters
Acid Bite Duration
Recommended Bath Time62.7 minutes
Calculated Bite Speed0.637 µm/min
Target Depth: 40 microns (1 micron = 0.001 mm)

Process Notice:

Calculated bite rates are structured for a chemical temperature of 20°C. If room temperatures are lower, add 10% to the etching time; if higher, reduce by 10%. Check depths periodically.

Rates and formulas are derived from standard fine-art printmaking studio guides. Chemical formulations should always be verified under a test strip sequence first.
