On Inspection Methods for Sequences of Crossed Writings and Seal Stamps in Laser Printing

朱墨时序是文件检验工作的重要对象,其中激光打印文件朱墨时序检验难度较大。在实践中,激光打印文件朱墨时序适用检验方法主要有光学显微检验法、荧光检验法、测量笔画增宽度检验法、定影转印法和计算机软件辅助检验法。在适用中,适用激光打印文件朱墨时序检验方法,要注意各种方法的适用特点,应遵循先无损后有损原则,同时强调进行综合检验。

Sequences of crossed writings and seal stamps is the key part of documents inspection in which inspection of sequences of crossed writings and seal stamps in laser printing is much more complicated. In practice, inspection methods for sequences of crossed writings and seal stamps in laser printing mainly include those through optical microscopes, fluorescent, measuring the stroke width, fixing transfer printing and computer software-assisted technique. In application of inspection methods for sequences of crossed writings and seal stamps in laser printing, we should emphasize on the different application features of different techniques, following the principle of lossless subsequent to loss and integrated inspection.
