提出了使用机器视觉和神经网络等技术构建印刷墨量在线检测系统,介绍了由机器视觉采集印刷图像，以及使用神经网络计算印张上各墨区CMYK四色油墨墨层厚度的方法。最后通过实验验证了神经网络的可行性，并编程实现了这一系列过程。

A printing ink quantity on-line detection system using machine vision technology and neural network was put forward. The method of printing image collection and thickness calculation of CMYK inks in each ink area using neural network technology was introduced. The system was constructed by programing and its feasibility was proved by experiment.
