摘要： Halftoning algorithms such as error diffusion, blue noise mask, and void and cluster mask are known to produce visually pleasing, random, homogeneously distributed patterns of dots on output devices such as color displays or printers, for example. These algorithms are extended to take advantage of the mechanisms of each that cause a homogeneous distribution of dots of one colorant to produce a substantially homogeneous distribution of dots when using multiple colorants. The number of dots of each colorant are combined to form an output dot level number of dots that is caused to be substantially homogeneously distributed.

摘要： In an ink jet printer, bleed between the boundaries between color and black are avoided by printing process black and black ink in an alternating pattern for the first two dots. Logic (62) determines the boundary from a bit map and issues the control signals for alternating lines (66, 68). Best results are experienced when the process black is printed before the black ink as the vehicle of the colored inks apparently supports penetration of the black ink.
摘要翻译：在喷墨打印机中，通过以前两个点的交替图案打印黑色和黑色墨水来避免颜色和黑色之间的边界之间的渗色。逻辑（62）从位图确定边界并发出用于交替线（66,68）的控制信号。当黑色墨水打印出黑色墨水时，由于彩色墨水的车辆显然支持黑色墨水的穿透，所以经历了最佳的效果。

摘要： Digital halftoning is used to reduce the number of pixel levels used to represent a multiple dot plane image to a smaller number of pixel levels for display on an output device such as an ink-jet printer. Two algorithms commonly used to halftone the dots of a given dot plane are error diffusion and ordered dither. Error diffusion produces patterns of dots that are pleasing to the human visual system but is computationally complex. Ordered dither operates quickly but produces patterns of dots that are visually objectionable. A method is taught in the present invention that employs error diffusion to halftone dot planes that contain relatively dark dots that are visually apparent, and employs ordered dither to halftone dot planes that contain relatively light dots that are not noticeable. The resulting output is pleasing to the human visual system and computed quickly.
摘要翻译：数字半色调用于将用于表示多点平面图像的像素级数减少到更少数量的像素级，以便在诸如喷墨打印机的输出设备上显示。通常用于对给定点平面的点进行半色调的两种算法是误差扩散和有序抖动。错误扩散产生对人类视觉系统令人满意的点，但是计算复杂的点的图案。有序的抖动操作迅速，但产生视觉上令人反感的点阵图案。在本发明中教导了一种在视觉上包含相对较暗的点的半色调点平面上使用误差扩散的方法，并且使用具有不明显的相对较浅点的半色调点平面的有序抖动。产生的结果令人满意的人类视觉系统并迅速计算。

摘要： A host computer transmits raster information to a multi-color ink jet printer. The printer includes a printhead connected with an electrical processor. The printhead includes a plurality of arrays of ink jetting heaters. Each array of ink jetting heaters corresponds to a different color ink to be jetted onto the print medium, and is offset relative to an adjacent array of ink jetting heaters in an advance direction of the print medium. First raster information for a first raster is transmitted from the host computer to the electrical processor of the printer. The first raster information is associated with a first array of ink jetting heaters. The print medium is printed on by selectively actuating the ink jetting heaters of the first array of ink jetting heaters, using the first raster information. After the first printing step, second raster information for a second raster is transmitted to the electrical processor. The second raster information is associated with the first array of ink jetting heaters. After the first printing step, third raster information for the first raster is transmitted to the electrical processor. The third raster information is associated with a second array of ink jetting heaters. After the second and third transmitting steps, the print medium is printed on by selectively actuating the ink jetting heaters of the first and second arrays of ink jetting heaters, respectively using the second and third raster information.

摘要： The invention is directed to a method of transmitting data from a host computer to a printer. Image data is provided which represents at least a portion of a print image to be printed by the printer. Locations of aboslute zero values in the image data and locations of non-absolute zero values in the image data are defined. The locations of the absolute zero values and the locations of the non-absolute zero values are mutually exclusive from each other. Both host computer and the printer are instructed of the locations of the absolute zero values in the image data. Only the image data having non-absolute zero values is transmitted from the host to the printer.

摘要： An error diffusion halftoning technique calculates only two error terms with one being divisible by two and the other being divisible by four. This is accomplished through using a modified Floyd and Steinberg type filter preferably having weights of 8-0-4-4 expressed in clockwise sequence from the origin. The direction of scanning is preferably reversed each scan line.
摘要翻译：错误扩散半色调技术仅计算两个误差项，一个可被二除，另一个可除以四。这通过使用优选具有从原点顺时针顺序表示的重量为8-0-4-4的改进的Floyd和Steinberg型过滤器来实现。扫描方向最好是每条扫描线都相反。
