Printing quality and efficiency of today's printing industry an important issue, and the quality of detection technology is at a critical position, as a result of continuous high-speed printing may lead to quality variation, if timely identification and to determine immediately take appropriate adjustment means, can significantly improve printing quality, in view of the traditional quality inspection process complicated, lengthy and inefficient, vulnerable due to human error factors, therefore, the research and application of digital image processing technology, analysis of Color Control Strip the composition of the project, individual development of different detection mode Group to carry out Color Control Strip offline detection, can be a guide to control access to the printing table for all items of information to monitor the online printing defect variation, to reduce printing costs and enhance the added value of printing with the purpose of industrial competitiveness.
