巴黎造币局（Monnaie de Paris）100–200 mm 大铜章的浮雕高 1–2 mm、最深细节 0.1 mm 级，靠"多击精压"成型：紫铜/青铜坯经 400–800 t 精压机连续击压 2–4 次，击次间低温退火（400 °C）并酸洗抛光坯面，让金属逐次填满模腔。模面抛至镜面并刻防磨斜纹圈口；成品浮雕边缘"锐线"来自末击时压力超出流动所需 20–30%。这套"预热-击压-回火"节拍对工作室级浮雕压制同样是黄金参照。
Monnaie de Paris strikes its 100–200 mm copper medals to 1–2 mm relief with 0.1 mm-class detail through multiple-strike coining: copper/bronze blanks take 2–4 blows on a 400–800 t press, with low-temperature anneals (400 °C) and acid pickle between strikes to keep metal flowing into the die. Dies are mirror-polished with anti-gall ring grooves; the crisp final edge line comes from a last blow 20–30% above flow pressure. This heat-strike-settle rhythm is the gold reference for studio-scale relief pressing too.
