精品酒店与餐厅的导视系统偏好酸蚀黄铜标牌（3 mm H59 板，字深 0.3–0.5 mm）：丝印感光阻蚀 → 45 ℃ FeCl3 喷淋蚀刻 25–40 min → 填黑漆或黑环氧 → 拉丝 + 清漆。一套 12–30 块的定制订单在小型工作室的交付周期 5–7 天，报价 300–800 元/块；相较激光打标，酸蚀边缘无热影响区、字底哑光质感更受设计师青睐。返单只收制版费 30%，长期客户年均返单 3–4 次构成稳定收入。
Boutique hotels favour acid-etched brass signage (3 mm H59, 0.3–0.5 mm letter depth): photoresist, spray-etch 25–40 min in 45 °C FeCl3, fill with black lacquer or epoxy, brush and lacquer. A 12–30 piece set takes a small shop 5–7 days at ¥300–800 each; designers prefer etching to laser marking for its heat-free edges and matte letter floors. Reorders pay 30% of the setup fee, and long-term clients returning 3–4 times a year form the stable revenue base. ---
