  • Color measurement device with error detection
    Patent number: 7636163
    Abstract: A color measurement device includes an error detection function for color printing control. The color measurement device includes an optical measurement head, the optical measurement head being moveable linearly along a color bar region of a printing sheet, and being configured for making color measurements with respect to the color bar, and for detecting color measurement errors by determining whether such color measurements are being made at least in part with respect to regions of the printing sheet other than the color bar region. The optical measurement head may further include a pixel array for tracking a center trajectory of the color bar for purposes of detecting the color measurement errors, and a color measurement engine for purposes of making the color measurements with respect to the color bar. The color measurement device may further include a motion control element and a mechanical track to guide the optical measurement head along the color bar region.
