摘要： To determine spectra, integrated multiple illuminant measurements from a non-fully illuminant populated color sensor may be converted into a fully populated spectral curve using a reference database. The reference database is partitioned into a plurality of clusters, and an appropriate centroid is determined for each cluster by, for example, vector quantization. Training samples that form the reference database may be assigned to the clusters by comparing the Euclidean distance between the centroids and the sample under consideration, and assigning each sample to the cluster having the centroid with the shortest Euclidean distance. When all training samples have been assigned, the resulting structure is stored as the reference database. When reconstructing the spectra for new measurements from the sensor, the Euclidean distances between actual color samples under measurement and each cluster centroid are measured. The spectra are then reconstructed using only the training samples from the cluster corresponding to the shortest Euclidean distance, resulting in improved speed and accuracy.

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 method and device detect printing defects on prints produced by an electrostatic printing device and, in response, place the electrostatic printing device into a diagnostic mode. While in the diagnostic mode, the method and device charge an image bearing surface of the electrostatic printing device to a uniform potential charge and disable all light emitting devices of the electrostatic printing device that could alter the uniform potential charge. Next, this method and device transfer marking material to the image bearing surface to create a test image and print at least one test patch by transferring the test image from the image bearing surface to a sheet of media. This method and device evaluate whether the test patch includes the printing defects and identify whether the light emitting devices of the electrostatic printing device are defective, based on whether the test patch includes printing defects.

摘要： A method and system generates and administers an individualized student worksheet. A set of problems and a unique embedded data pattern are generated and printed on a worksheet substrate. A teacher may point a camera pen point at an area of the pattern to identify the substrate and a location on the substrate. Based on this information, the method and system may access a worksheet file to identify the problem whose physical position corresponds to the captured embedded data. The system may present the problem's solution to the teacher, who may then use the pen to mark the problem as correct or incorrect, and optionally annotate notes for the student, teacher or others. The camera pen may collect the teacher's marks and annotations and store them with the worksheet file for later retrieval.

摘要： Methods and systems print a multi-color test pattern using a printing device to create a printed test pattern when the printing device is producing a printing defect. The methods and systems scan the printed test pattern to produce a scanned image and decompose the scanned image into color blocks using the computerized device. The methods and systems create intensity profiles of the color blocks using the computerized device and compare at least two of the intensity profiles of different colors to determine whether the intensity profiles indicate correlated printing defects using the computerized device. The methods and systems indicate, through the computerized device, whether a potential defect within a common printing element of the printing device or is located within one or more of the color printing elements of the printing device, depending upon whether the intensity profiles have correlated printing defects.
