摘要： What is disclosed is a novel system and method for quickly characterizing a reflectance sensing device without measuring the full set of characterization color patch training samples currently used in manufacturing and characterizing individual sensors. In accordance with the teachings hereof, measurements of training samples taken with a previously manufactured ‘fleet master’ sensing device are adapted, in a manner more fully disclosed herein, based upon knowledge of the wavelengths of the illuminators used for both the subject and fleet master sensors, as well as spectral reflectance response of the training samples as measured by a reference spectrophotometer device. Utilizing the adapted measurements of the fleet master device, a reconstruction matrix can be quickly constructed for the subject sensor. The present system and method provides reasonably good accuracy using pre-existing measurement data. This results in manufacturing cost savings on a per-sensor basis.

摘要： A method for estimating color measurements of color samples includes printing a color sample based on input data, measuring a color of the printed color sample with an in-line spectral sensor at a first temperature, and estimating a color of the printed color sample which would be output by a reference spectral sensor at a second temperature. The estimation is based on a thermochromatic model which represents relationships between measured colors of printed color samples on the in-line spectral sensor at the first temperature and the reference spectral sensor at the second temperature. The reference spectral sensor is a different type of sensor from the in-line spectral sensor, so the color response of the two spectral sensors is different, even when the measurement conditions are identical. Consequently, a set of printed spot color samples generate different measured colors at the second temperature on the in-line spectral sensor from the reference spectral sensor. The exemplary method allows these differences, as well as measurement temperature differences to be accounted for in the estimation.

摘要： A system and method for full width scanning color analysis of a printed media sheet are disclosed. The full width array spectrophotometer system includes one or more substantially linear elongated illumination arrays of closely spaced multiple illumination sources. The sources include sets of illumination sources, including a first set of different color illumination sources and a second set including one or more UV-emitting illumination sources. The sets are arranged to span a printer paper path or other object path to illuminate a band extending transversely across a printed print media sheet or other object moving in the path. A full width array light imaging sensor includes an elongated array of multiple closely spaced photodetectors for detecting plural colors and is positioned adjacent to and extending substantially parallel to the linear array(s) to receive radiation reflected from the transverse illuminated band.

摘要： A method and system for optimal node placement of a color correction table first generate a high resolution color correction table. A low resolution color correction table is generated. Each node of the low resolution color correction table has a corresponding color correction value generated by interpolating the color correction values of the high resolution color correction table. A reconstructed color correction table is generated, and each of the nodes of the reconstructed color correction table has a corresponding color correction value generated by interpolating the color correction values of the low resolution color correction table using an interpolation method identical to an output device interpolation method. Differences between the color correction values of the reconstructed and the high resolution color correction table are quantified into a measure of error, and the node locations of the low resolution color correction table are adjusted, and the procedure is repeated.
