摘要
与传统的人眼套印检测方法相比,基于数字图像的套印误差检测系统具有识别速度快、精度高、便于数字化管理、符合短版活业务增长趋势等优点,已成为数字化印刷设备领域研究的重要课题。对近年来国内基于数字图像处理的套印误差检测系统的研究进展进行了综述,对比了目前使用的套印标记、图像分割算法、套印误差参数计算的优缺点,分析了套印误差检测系统中的常见问题。
Contrasting with the traditional detection method depending on eyes, the system for detecting register error based on digital image owns fast recognition rate and high precision, facilitates for digital management and meets the increasing trend of the short run. It has become an important issue of the digital printing equipment. This paper outlines the domestic advance in the system for detecting register error based on digital image. The advantages and disadvantages of the register marks, image segmentation algorithms, parameters calculation for register error are compared. The common problems in the system are analyzed.
