Apparatus for colorimetry gloss and registration feedback in a color printing machine

A method and apparatus for measuring colorimetric, gloss and registration data on a substrate exiting a printing machine. A detector using a series of red, green, and blue filters collects image data and maps the collected data to absolute color coordinates. The apparatus is factory calibrated to th...

Beschreibung
Zusammenfassung:	A method and apparatus for measuring colorimetric, gloss and registration data on a substrate exiting a printing machine. A detector using a series of red, green, and blue filters 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 and feedback delivered to the various imaging modules. The detector allows on the fly data to be obtained and machine specific corrections to be made.
