ABSTRACT
In modern industries, it is important to monitor the output process by a suitable and
low cost method. However, the vision-based techniques are the most powerful
methods to collect different types of feedback depending on the used image
processing algorithm. This paper describes a low cost mechatronic system for color
to color registration in sheet-fed offset printing based on color image analysis. The
proposed system consists of hardware construction and software algorithm with
commonly available techniques. A complementary metal oxide semiconductors
(CMOS) sensor is used to capture the image which is processed via the image
processing software. The closed loop system control is based on the decision taken
by the image analysis algorithm. The proposed mechatronic system succeeded to
decrease detecting and correcting time of miss registration compared with the
manual process.
