摘　　要：在印刷工业生产中,套准是影响彩色印品质量的决定性因素。本研究针对印刷生产过程中人工检测套准效率低、精度不高等问题,建立了一种基于序贯相似性检测算法(SSDA)的印刷套准精度快速检测方法。针对常用的叠印型套准标记,首先将采集到的标记图像通过分色得到CMYK四色图像,然后基于SSDA算法对套准标记进行准确定位并实现套准误差的自动检测。实验表明:该方法检测精度和效率较高,能够满足实际工业生产需求。Overprinting accuracy detection is an important problem in multi-color printing which has a direct influence on printing quality. A method based on sequential similarity detection algorithm （SSDA） was proposed to improve the detection efficiency and precision in the study. The general overprint mark in industry was taken as the study object and divided into CMYK by setting the segmentation threshold in CMYK color space. And then SSDA was applied to detect the overprinting accuracy. At last this method was proved to be effective to meet the actual demand of industry production.
