Detecting registration deviation accurately plays an important role in the automatic overprint control system.
准确检测套印偏差是印刷机自动套印系统中最为关键的技术;针对印刷色标图案的特点,提出了一种新的基于图像匹配的套印误差检测方法,通过相关匹配处理获取各单色色标的位置,并巧妙利用色标圆线的直径确定了系统的标称分辨率,进而计算出各色组问纵向和横向的套印误差;文中详细给出了算法原理和实验结果;相对于经典的边缘检测方法,图像匹配技术充分利用了色标图案的整体信息;实验结果表明,该方法对像素灰度的变化和系统噪声具有鲁棒性,检测精度高。
