摘要： Systems and methods of halftoning an image for extended-colorant printing image spot colors are provided which perform a quality ranking of a plurality of periodic halftone screens to be used in halftoning the image and an objectionability ranking of the colorants used to produce the one or more image spot colors. Halftone screen-to-colorant assignments are then made using a ranked ordered pairing of the ranked screens and ranked colorants. The image is halftoned using these assignments and the results can be printed or saved for future printing. Pixel tags can be used to identify the ranked ordered halftone screen-to-colorant assignments.

摘要： A special test pattern and image quality analysis system and process for evaluating the test pattern are provided to accurately measure color-color registration in an image output device that prints in CMYK color. The process is robust even when using relatively low-resolution CCD-based scanners and also is unique in that the process automatically factors out errors originating from skew between the detector and the subject of measurement. Further, registration of each of C, M, and Y relative to K are independently determined. The test pattern includes an upper part and a lower part, with both the upper and lower parts having a black K component and the upper part also including color components for C, M and Y. The system and method have potential for being built in to color printers or copiers to allow measurement of color misregistration within the paper path and automatically correct for color registration errors.
摘要翻译：提供了一种特殊的测试图案和图像质量分析系统以及用于评估测试图案的过程，以准确测量以CMYK颜色打印的图像输出设备中的颜色配准。即使使用相对较低分辨率的基于CCD的扫描仪，该过程也是稳健的，并且也是唯一的，因为该过程自动地导出来自检测器和测量对象之间的偏差的误差。此外，分别确定C，M和Y中每一个相对于K的配准。测试图案包括上部和下部，上部和下部均具有黑色K分量，上部还包括C，M和Y的颜色分量。该系统和方法具有内置于彩色打印机或复印机，以允许测量纸张路径内的颜色重合失调，并自动校正颜色配准错误。

摘要： A method to form a seven-color CMYKRGB or eight-color CMYKRGBW image having reduced toner pile height than in conventional four-color xerography, resulting in more uniform image gloss. The method includes the steps of: forming first spot next to spot toner images by placing spots of toner of a first color next to spots of toner of a second color on a first photoconductive member; forming second spot next to spot toner images by placing spots of toner of a third color next to spots of toner of a four color a second photoconductive member, and transferring said first and second spot next to spot images to form a composite spot next to spot image on an intermediate imaging member.

摘要： A release agent management (RAM) system incorporated in an electrophotograpic printing machine having a heat and pressure fuser assembly to aid in the removal of fused copies from the fuser roll. The fuser assembly includes a heated fuser roll, a pressure roll, a sump containing a quantity of release agent, a pair of metering rolls and a donor roll. Each of the metering rolls is immersed in a quantity of release agent and is able to selectively be brought into contact with the donor roll. The donor roll acts as the transport to transfer release agent from either or both of the metering rolls to the heated fuser roll. The dual roll metering system provides a RAM system which can uniformly provide two or more oiling rates varying with the process speed of the printing machine. It also provides a RAM system which can switch oiling rates without creating oil slugs which ultimately reach the fuser thereby degrading copy quality.

摘要： What is disclosed is a method for vehicle occupancy detection using a single band infrared imaging system. First, an infrared image of a vehicle intended to be processed for human occupancy detection is captured using a single band infrared camera set to a predefined wavelength band. A candidate sub-image is identified within the captured image. A cumulative histogram is formed using the reflectance values of each pixel in the candidate region. A threshold reflectance value is then determined from the cumulative histogram using a pre-defined cumulative occurrence fraction value which corresponds to a value equivalent to an average sized human face. Embodiments for setting the threshold reflectance value are disclosed. Thereafter, human occupants can be distinguished in the image from the vehicle's interior by comparing pixel reflectances in the sub-image against the threshold reflectance value.
