Decorated or treated with aquatint, a printmaking technique that creates subtle tonal gradations using acid and resin.
From 'aquatint' (from Italian 'acquatinta,' meaning 'watercolor-like tint') plus '-ed' (past participle). This technique emerged in 18th-century Europe as printmakers sought to mimic watercolor.
Aquatint was the 18th-century printmaker's answer to a artistic problem: how do you create the soft, delicate tones of watercolor in a print? The answer involved sprinkling tiny bits of resin that the acid would carve around.
