摘要
检测并控制制版印刷过程中的网点面积(率),是提高印刷质量的重要课题。分析了传统检测方法的不足之处,以作为DMS910校正标准的显微网点灰度图像为检测对象,用不同的算法进行了检测分析,获知类别方差自动门限法对中间调精度较高,为研制印刷网点面积检测系统奠定了一定基础。
To measure and control the dot area in plate -making and printing process is an important subject to improve print quality. The purpose of this research was to select a better method. The shortcomings of traditional methods to measure the dot area were analyzed, and the gray image as the calibration standard of DMS910 was measured by various algorithms. It was found that the accuracy of OTUS is higher in the measurement of middle tone. The analysis also provided some guidelines for researching and developing the dot area measurement system.
