    Abstract: Systems and methods are provided that improve the registration between the color separation images. The systems and methods control the output of the image data for one or more of the color separation images and the velocity of an image-carrying member to remove or reduce registration offsets based on determined position and velocity of the image-carrying member. A position-determining sensor on an image-carrying member device module is used to determine the process-direction position of the image-carrying member to provide real time motion information by simultaneously sensing a plurality of position-determining marks. A position-determining controller determines the process-direction position of the image-carrying member by detecting the plurality of position-determining marks using the position-determining sensor and averaging or correlating the detected data.

    Abstract: 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.

    Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for improving alignment between color resolved images. SOLUTION: By controlling the output of image data and the speed of an image carrying member for every one or more color resolved images based on the measured position and speed of the image carrying member, the deviation of the alignment is eliminated or reduced. A position measuring sensor 352 on an image carrying member device module is used to measure the position of the image carrying member in a processing direction and provides movement information in real time. A position measuring controller 248 detects the pattern of a position measuring mark by using the sensor 352 and processes the data detected by averaging and correlating in order to eliminate a detection error, whereby the position of the image carrying member in the processing direction is decided.
