Study on the Registration Testing of Color Digital Printing Machine

The paper designs a kind of testing chart for registration detection which has a property of strong adaptability and expansibility. After scanning the testing charts output by different color digital printing machines, the corresponding digital samples are obtained and identified by Image-quality software. Through subjective and objective analysis based on the data of the digital samples, a method is proposed to evaluate the accuracy of registration of the color digital printing machine. The experiment shows that it cannot only be used to effectively judge registration of different color, but also can conclude which registration accuracy coming from different color digital printing machines is better. It is proved that this method can be used to evaluate the accuracy of color digital printing machine quickly and successfully; it has certain practice guiding sense for development and application of registration measurement technology.
