对卷筒纸印刷过程中的纸张变形测量方法进行了分析,利用 CCD 成像和图像处理技术进行了信号采集、图像检测、数据分析等的方法研究和程序设计,并在卷筒纸平版胶印机上进行了实验,检测结果与理论分析基本吻合,方法验证可行,可作为纸张变形研究和生产质量管理的有效手段。

Measuring methods of web deformation under printing condition were analyzed. CCD camera and image analysis technology was used to develop the method of signal sampling, image detection, and data analysis. Corresponding program was developed. Experiment was carried out on a web offset press. The results showed the deformation data produced with the method is well matched with theoretical analysis; the method was proved to be correct and feasible and can be used for further study of printing paper deformation and printing quality control
