Warm Imprinting with Heated Masters
热压印：加热母本的深转印
标签：热压印, 加热母版, 深纹理, 金属母版
金属母版加热到 150–200 ℃ 后压印，铜板局部软化使纹理深度比冷压提升 30–50%，边缘也更锐利。适用金属蕾丝、机刻钢辊等耐热母本（织物、树脂不可）。控制要点：母版与压头同温（避免坯料温降不均）、压前铜板 200 ℃ 预热、压下保压 3–5 s。热压后需再退火消除局部硬度差，方便后续成形。此法介于冷压印与热冲压之间，工作室用喷灯即可实现。
Heating metal masters to 150–200 °C before pressing softens the copper locally, deepening transfer 30–50% with crisper edges—suitable for metal lace or machined steel rollers (not fabric or resin). Keep master and platen at the same temperature, preheat the copper to 200 °C, and dwell 3–5 s. Re-anneal afterward to even out hardness for further forming. A torch is enough at studio scale—between cold imprinting and hot stamping. ---
