摘要： A method of generating one image dot from three image pixels. The values of the three pixels are summed. If the sum indicates a dot that is equal to or darker than ⅔ black, the two outer thirds of the dot are set to black and the central third is set to a shade of gray. If the sum indicates a dot that is equal to or lighter than ⅓ white, central third of the dot is set to white and the outer two thirds are set to a shade of gray. The shades of gray are generated by using high addressability, and error diffusion is used to diffuse the rounding off errors implicit in the high addressability process.
摘要翻译： 从三个图像像素生成一个图像点的方法。 将三个像素的值相加。 如果总和表示等于或暗于⅔黑色的点，则点的两个外部三分之二设置为黑色，中央第三个设置为灰色阴影。 如果总和表示等于或小于1/3的点，则点的中心三分之一设置为白色，外部三分之二设置为灰色。 通过使用高可寻址性生成灰色阴影，并且使用误差扩散来扩展在高可寻址性过程中隐含的舍入误差。

摘要： An object optimized printing system and method includes a page description language decomposing system, a command instruction and data generating system and an image output terminal controller. The PDL decomposition system inputs a plurality of pages in the page description language and locates the plurality of objects forming each page and their object types. Based on the determine object types and any explicit rendering commands, the PDL decomposition system automatically generates rendering tags for each of the objects. The rendering tags are used to control the command instruction and data generating system, the IOT controller and/or the IOT to optimize the printing by the IOT on an object-by-object basis. Based on the objects and the generated rendering tags, the command instruction and data generating system generates the differing types of data and the command instructions on a scanline-by-scanline basis. The generated command instructions and data are output to the IOT controller scanline-by-scanline. The data output to the IOT controller includes metabit data generated from the rendering tags. The metabit data is used to control various subsystems of the IOT controller and the IOT to optimize the printing characteristics, of the IOT for each differing object on each scanline. The metabits can optimize such processing subsystems as halftone generation, halftone screen size and angle, color space transformation, tone reproduction curve, IOT output correction and the like. Using this system, each page output by the IOT has the printing characteristics for each object within the page optimized to the object's types.

摘要： A circuit which uses less memory to store halftone arrays in a high addressability printer by storing regular halftone arrays as low addressability arrays and by outputting each pixel a number of times, the number being the ratio of high to low addressability. For example, if a high addressability system uses 4 sub pixels for each pixel, then one value of each low addressability array is stored in one location and the halftone circuit is controlled to output that value 4 times, once for each sub pixel thus saving memory by a factor of 4.

摘要： The invention is an automatic way to create background images from custom images, enabling cost efficient generation of highly customized products; such as advertisements, checks, greeting cards, stationary, clothing, passports, licenses, identification badges legal documents and legal tender; by generating intermediate image data by over-enhancing the sharpness of the custom image data and subsequently generating modified image data by reducing the sharpness, color and contrast of the intermediate image, whereby the resulting modified image is pleasing to the average consumer without interfering with the application of the product on which the background image is applied.

摘要： A scanner generates a first set of M-bit signals representing an image in a document. A default table translates the M-bit signals into linearized N-bit signals where M>N. A color image processing module processes the N-bit signals to generate an image-dependent look-up table which, thereafter, is loaded into the scanner. The scanner then generates a second set of M-bit signals using a high resolution re-scan of the same image. The second set of M-bit signals are translated into N-bit signals using the image-dependent look-up table to generate an electronic representation with enhancement characteristics.

摘要： A method of halftone printing in four colors using, for cyan, magenta and black, halftone screens that will result in screening angles of 15, 45 and 75 degrees, as is the standard process in the art, and a halftone screen for yellow that will result in screening angles of 0, +60 and -60 degrees. This combination will diminish the 2 color moire patterns that result from the interaction between the yellow and one of the other colorants. The 0 and + or -60 degree screening angles are generated by using a screen that produces a four-centered cell having dots that are spaced to form hexagons, when the nearest neighbors of a central dot are connected by lines, as opposed to the conventional trapezoidal orientation.

摘要： A system facilitates printing of microtext. A processing component allows a user to create one or more microtext characters, wherein the characters are output as a data packet. An SRE code store receives and associates one or more SRE codes with the data packet, each SRE code is representative of a bit pattern, wherein the bit pattern is a grid of bits that are filled to create a particular pattern. A font bank receives the one or more SRE codes from the SRE code store and defines such codes via a font. A raster image processor receives the font from the font bank, decodes the font and outputs instructions to print the microtext.

摘要： This invention is a method of producing a set of TRC's for a color printer's secondary halftone screens that is correlated with the printer's primary halftone screens. The method makes use of the printer/screen characteristic data that is normally gathered during screen calibration. However, instead of progressing from the data to a normal calibration for the secondary screens, the method goes backward through the data starting with the finished primary screen TRC's. The method insures that for every primary screen density, the closest possible secondary screen density is used when the same digital value is specified.
