植物母本的干燥与保色预处理
标签：植物干燥, 保色, 压花, 叶脉
新鲜叶片含水 60–80%，直接压印纹理糊、转移浅。标准预处理：叶片夹入吸水纸 40 kN 压花器或书本重压 3–5 天至含水 <10%；想要叶脉立体，用 5% NaOH 煮 10–20 min 刷去叶肉、过氧化氢漂白后阴干。保色可用丙三醇:水=1:2 浸泡 24 h（维持柔韧不脆裂）。处理好的干叶密封干燥保存，可压印 2–3 次后更换。
Fresh leaves are 60–80% water and imprint weakly. Standard prep: press in blotting paper under a 40 kN flower press or heavy books 3–5 days to below 10% moisture. For raised vein detail, boil in 5% NaOH for 10–20 min, brush away mesophyll, bleach in peroxide, and air dry. Glycerol:water 1:2 soak for 24 h keeps leaves flexible. Store dry leaves sealed; each master yields 2–3 good impressions. ---
