摘要： A system using a spatial correction to improve the result of a printer calibration and correction is described. More particularly, in one form, a spatial correction may be used to pre-condition a printer for an improved color calibration. In another form, spatial correction and color calibration are addressed in the same process for color correction.

摘要： A calibration or characterization system is provided wherein the number of repeated patches or the size of a patch of a given color is printed to be approximately proportional to the square of the expected noise level. In that way, when multiple measurements for a given patch are averaged, all patch averages have approximately the same reliability.

摘要： Systems and methods for detecting image quality defects in images rendered by a rendering device. Original image data is rendered by an image rendering device, and the rendered image is captured by an image capturing device. Regions of interest may be identified to provide information indicating where image quality defects of the rendering device, may be identified. At each region of interest, the original image data may be compared to the captured image data of a corresponding region of interest to determine color difference of the captured image at the region of interest. The color difference may be subsequently converted from a device independent color space to a device dependent color space. Based on the converted color difference and input intensity of the original image data at the region of interest, a colorant error may be determined for the region of interest, and/or a scan line and a row line including the region of interest.

摘要： An image rendering system includes a digital front end to electronically analyze image data to generate geometry dependent image content information. A print engine, operatively connected to the digital front end, renders the image data. A print engine controller, operatively connected to the digital front end and the print engine, controls various parameters of the print engine. The digital front end transmits the image content information to the print engine controller. The print engine controller adjusts a parameter of the print engine based on the transmitted image content information. The transmitted image content information may be coverage information, reload information, and/or toner pile height information. The parameter of the print engine adjusted based upon the transmitted image content information may be fuser temperature and/or process speed of a developer housing and/or flow rate of toner into a developer housing.

摘要： A technique for observing signaling on the traces between ICs on a PC board without introducing significant signal degradation is provided. A route-through connector footprint allows the use of a standard connector without the use of stub traces. The route-through connector footprint allows a standard connector to be introduced directly into the line traces routed between ICs. Because stub traces are not used, this technique for mechanical interconnection into the line traces on a PC board allows for a single board layout to be used for both test and production. Additionally, because stub traces are not used, signal quality is minimally impacted and testing can be performed at operational speeds improving the reliability of the test function. The use of a route-through connector footprint additionally saves PC board space and cost.

摘要： A method for identifying and correcting for spatial variation within scanning bars includes performing diagnostic scans of at least one sheet, in which a sheet(s) is scanned in various orientations and translations, with each of the orientations identified. The diagnostic scans are registered with one of the individual diagnostic scans to produce registered scans. The registered scans are averaged to create a master scan corresponding to the sheet, such that the master scan is indicative of the spatial variation within the sheet.

摘要： Colors similar to those which would be used in calibrating a target printer are printed on a printer of the same model and with the same materials set as anticipated for the printer calibration. These all lie within a substantially reduced portion of the gamuts of both the printer and scanner. A scanner characterization is derived only for those portions of color space corresponding to the printed colors. This may be done using spline fitting in one or more dimensions. While generic scanner calibrations generally have errors in excess of ΔE=7, with these techniques values generally less than 1.7 were obtained. This is sufficient for printer calibration.
摘要翻译：类似于用于校准目标打印机的颜色将打印在相同型号的打印机上，并且使用与打印机校准所预期相同的材料。这些都位于打印机和扫描仪的色域的基本上减少的部分内。扫描仪表征仅针对对应于打印的颜色的那些颜色空间的部分导出。这可以使用在一个或多个维度中的样条拟合来完成。虽然通用扫描仪校准通常具有超过DeltaE = 7的误差，但是这些技术值通常小于1.7。这对于打印机校准是足够的。
