摘要： A composite toner image made up of first and second toners is formed on an image member. A first electrostatic image of a first polarity is formed on the image member. That electrostatic image is toned with a first toner of the first polarity. The image member is imagewise exposed to create a second electrostatic image also of the first polarity. Exposure is overlapped into the portion of the image member under the first toner image to prevent any charge on the photoconductor of the first polarity underneath the first toner image from repelling toner into the portions of the second electrostatic image that are discharged. Preferably, the second exposure is accomplished through the base of the image member in order to thoroughly expose portions of the electrostatic image underneath the first toner image.

摘要： A copier or a printer 10 includes a controller 16/30 with a rendering algorithm that groups sets of adjacent pixels into sets of adjacent cells where each cell corresponds to a halftone dot of an image. The algorithm operates in conjunction with a gray scale printhead 22. In sending data to the printhead, the controller 16 parses a scanned image and set the exposure for each pixel in accordance with a growth and density program. The algorithm selectively grows halftone dots from zero size to a desired size equal to or less than a maximum size. It repeats this step for the rest of the pixels until the cell is at its desired size and at an initial density. If a higher density is desired, the algorithm selectively adjusts the fully grown cells by sequentially increasing the level of exposure of each pixel in the cell. The image is developed with developer including a hard magnetic carrier and toner.
摘要翻译：复印机或打印机10包括具有渲染算法的控制器16/30，其将相邻像素的集合分组成相邻单元的集合，其中每个单元对应于图像的半色调点。该算法与灰度级打印头22结合操作。在向打印头发送数据时，控制器16根据增长和密度程序解析扫描图像并设置每个像素的曝光。该算法将半色调点从零大小选择性地增长到等于或小于最大尺寸的期望大小。对于剩余的像素重复此步骤，直到单元格处于其所需的大小和初始密度。如果需要更高的密度，则算法通过依次增加单元中每个像素的曝光程度来选择性地调整完全生长的单元。图像用显影剂显影，包括硬磁性载体和调色剂。

摘要： A method for color correction of an image having an insignia portion in a multi-module printer (10). A first color profile is calibrated for a four-color image. A second color profile is calibrated for a four-color image with a transparent toner layer on top of the insignia portion of the four-color image. The image data is then buffered in a color input band buffer (40) and processed through the first (50) and second (60) color profiles in a color management module. The processed image data is stored in an output band buffer (70, 80) corresponding to the image data processed through each color profile. Clear toner input band data stored in a clear toner input band buffer (30) is compared with the processed image data in each output band buffer (70, 80) to select an output signal (100) on a per pixel basis to send to the multi-module printer (10).

摘要： By using a high or low viscosity transparent toner, with respect to the other color toners, and different amounts of transparent toner lay-down, the gloss of an image printed by an electrophotographic device may be adjusted. By also applying the transparent toner as a negative mask, the differential gloss of the image may be reduced while still adjusting the gloss of certain portions of the image. Further, because different gloss levels may appear different at different viewing angles, transparent toner may be laid down to encode a transparent image within the image being printed. Such a transparent image may be useful as, for example, an authentication means for a document. Additionally, by varying the gloss levels on particular aspects of a printed image, multiple images of different gloss levels, which are prominent at different viewing angles can be made, thereby, a three-dimensional image effect can be achieved on the printed page.

摘要： A method and apparatus for transmitting and receiving image data and control characters across an interface that is subject to noise for output to a printer. The image data and the control characters are transmitted across the interface to a receiver device. A determination is made as to whether or not a line of image data has been sufficiently transferred to the receiver device and, if the current line of image data has not been sufficiently transferred, there is provided for output to the printer a prior sufficiently received line of image data in replacement of the current line of image data so that the prior line of image data is printed at least twice in succession.
