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.
