铜版画家以松香粉热固形成颗粒防蚀层，局部入酸产生渐变灰阶，得以表现明暗。该工艺对温度与酸浓度极敏感，需反复试版。成品可印数十至上百张。

Printmakers fuse rosin dust into a granular resist and selectively etch to build tonal gradients for light and shadow. The process is extremely sensitive to temperature and acid strength, requiring repeated proofs. A plate can yield dozens to over a hundred impressions. ---
