Abstract: According to the structural feature and copying theory of the carbonless copy paper， a research on the formation order between carbonless copy handwriting and stamp impressions is carried out， in order to explore the regular characteristics of the formation order. Based on micro-examination results， which is more intuitive to analyze the micro-morphology of intersection of crossed writing and stamp impressions， several practical methods are proposed to accurately determine the sequence of crossed writing and stamp impressions.

Key words: carbonless copy paper, microcapsule, stamp impression, sequence of crossed writing and stamp impression.

摘要： 依据无碳复写纸的制造工艺、结构特点和复写原理，对无碳复写字迹与印文的形成时序特征进行探索，寻求判断两者形成次序的规律性特征以及检验依据和方法，以较为直观的显微检验，分析朱墨交叉点的微观形态，并提出利用微囊壳颜色分析、谷底显色及转印痕迹分析等方法对无碳复写字迹与印文的形成时序进行准确的认定。
