指以扫描、拍照建模等方式将实体拓片或器物纹样转为高分辨率数字图像（通常 600–1200 dpi）的档案形式，可经点阵化处理直接驱动激光蚀刻或打印转印，实现纹样永久保存与按需复制。常配哈希值登记以防篡改，是传统拓印的数字化延伸。
A high-resolution digital image (typically 600–1200 dpi) of a physical rubbing or artefact pattern, captured by scanning or photogrammetry. After halftone conversion it can drive laser etching or print transfer directly, giving permanent archiving and on-demand replication. A registered hash is often attached for tamper evidence—an extension of traditional rubbing into the digital realm.
