摘要
光敏印文色料与签字笔书写色料交叉重叠后,因互溶渗透不易形成层状结构而使判定朱墨时序的难度较大。光谱成像检验法是通过比较交叉点、纯印文色料、纯墨迹色料处的反射曲线位置来判定交叉时序关系。
Due to infiltration effect, it is a hard task to sequence photosensitive stamp impressions and signature pen writing. Spectral imaging can be used to determine the sequence by comparing the location of reflection curves of overlapping parts, photosensitive seal ink and signature pen ink.
