【摘要】 墨杠是一种常见的印刷故障,其产生的原因和解决的方法是印刷领域的研究热点。本文提出了一种基于纹理分析的墨杠检测方法:通过高速CCD采集待检测印刷图像,求解印刷图像与标准图像的差分图像,从而得到缺陷图像,并求其纹理特征,通过纹理特征判断墨杠的故障原因。最后,通过实验证明了该方法在印刷机墨杠诊断中的可行性。更多还原

【Abstract】 Roller-mark is a common problem in offset printing and its solution method is important for printing. A new detecting method of texture analysis was given in this paper. In this study, printing image was acquired with high-speed CCD. Compared the difference between printing image and standard image, a defective image was obtained. Then the reason of roller-marks was given by the texture recognition of defect image. Finally, experiments were taken to prove the feasibility and effectiveness of this new method for the roller-marks diagnosis in the offset printing machine.更多还原
