摘要： A system is provided that improves the registration between color separation images in a color imaging process. The image data for one or more of the color separation images and the velocity of an image-carrying member (350) are controlled to remove or reduce registration offsets based on determined position and velocity of the image-carrying member. A position-determining sensor (352) is used to determine the process-direction position of the image-carrying member to provide real time motion information. A position-determining controller (248) determines the process-direction position of the image-carrying member by detecting a pattern of position-determining marks using the position-determining sensor and processing the detected data through averaging or correlation to eliminate detection errors to thereby improve the accuracy of the positional determination.

摘要： A method and apparatus for measuring colorimetric, gloss and registration data on a substrate exiting a printing machine is described. A detector using a series of red, green, and blue filters (130,132,134) collects image data and maps the collected data to absolute color coordinates. The apparatus is factory calibrated to the specific colorants used in the printing machine. Gloss measurements are made using the same apparatus. Registration data between the various color separations is also obtained using detectors (140,142,144,146) and feedback delivered to the various imaging modules. The apparatus allows on the fly data to be obtained and machine specific corrections to be made.
