摘要： A method of forming a liquid pattern according to liquid pattern data on a receiving medium using a liquid drop emitter that emits a continuous stream of liquid from a nozzle that is broken into drops of predetermined volumes by the application of drop forming energy pulse is disclosed comprising associating a pixel area of the receiving medium with a nozzle and a time interval during which a plurality of fluid drops ejected from the nozzle can impinge the pixel area of the receiving medium. The time interval is divided into a plurality of subintervals that are, in turn, grouped into a plurality of blocks. Each block is defined as a printing block or a non-printing block. A drop forming energy pulse is provided between each pair of consecutive blocks and between the subintervals of each printing block. No drop forming energy pulses are provided between the subintervals of the non-printing blocks. The so-formed energy pulse sequence is applied to the stream of liquid causing the formation of small print drops and large non-print drops. The liquid pattern is formed on the receiver of print drops comprised of liquid emitted during subintervals associated with printing blocks. The block configuration is designed to ensure that non-print drops have the proper volume. In an alternate set of embodiments, individual subintervals rather than blocks of subintervals are individually defined as print or non-print subintervals subject to a non-print drop rule that forces non-print drops to be formed of adequate volume for differentiation from print drops and a maximum drop rule that ensures that non-print drops are not too large to be reliably captured and guttered.

摘要： The present invention generally relates to a method and apparatus for compensating for malperforming or inoperative ink nozzles in a multitone ink jet printhead so that high quality images are printed although some ink nozzles are malperforming or inoperative. Multitone printing is effected by printing a variety of droplets of varying volumes at a given pixel location. In compensating for a malperforming nozzle, a swath data signal is modified and one or more functional nozzles are assigned the printing data for a malperforming nozzle such that the volume of ink ultimately printed at pixel locations is substantially unchanged and the resulting image is free from degradation. Additionally, malperforming nozzles may be assigned values which represent the degree of image degradation that would be caused by printing with the malperforming nozzles, such that these values may be taken into consideration during the process of modifying the swath data signal for complementary recording.
摘要翻译：本发明一般涉及一种用于补偿多色喷墨打印头中的不正常或不工作的墨水喷嘴的方法和装置，使得虽然一些墨水喷嘴是不正确的或不起作用的，但仍打印出高质量的图像。通过在给定像素位置处印刷各种不同体积的液滴来实现多媒体印刷。在补偿不正常喷嘴时，改变条数数据信号，并为一个或多个功能喷嘴分配用于不正常喷嘴的打印数据，使得最终在像素位置印刷的油墨体积基本上不变，并且所得到的图像没有劣化。此外，不正常喷嘴可以被分配值，其表示由于使用不正常喷嘴而打印而导致的图像劣化程度，使得在修改用于补充记录的条数据信号的处理期间可以考虑这些值。

摘要： A block adaptive differential pulse code modulation (DPCM) system includes both a lossless DPCM processor responsive to blocks of pixel values for producing encoder command signals and a lossy DPCM compressor responsive to blocks of pixel values for producing encoder command signals. An encoder receives the encoder command signals from the lossless DPCM processor and lossy DPCM compressor and produces a compressed encoded bit stream. A switch responsive to a compression configuration signal and to the encoder command signals from the lossy compressor selectively passes the encoder command signals from the lossless processor or the lossy compressor to the encoder.

摘要： An image processor (14) supporting very high-speed printing. The image processor (14) preferably has two separate connections to a source (12) of the image being printed, e.g., a printer control bus (34) and an image data bus (36). The image processor (14) preferably accepts images from the image source (12) in commonly known graphics file formats, such as the well-known 24-bit, uncompressed TIFF file format. The image processor (14) is a multiprocessor implementation. Preferably, one processor (30) coordinates or “orchestrates” control of the printing system and handshaking with the image source via the printer control bus (34) and the other processor (32) functions as a raster image processor (RIP) processor (52) and accepts and stores images into the printer environment from the image source (12) via the image data bus (36). The RIP processor (52) preferably performs color separation on the image into color planes and transmits each color plane to a separate processing path from that point on in the imaging chain. Each color plane preferably has a separate imaging path out from a shared image data bus (62). This separate path for each color plane preferably includes a band manager (54), a print engine or nozzle controller (60), and a print head (58).

摘要： A method of selecting inkjet nozzle banks for assembly into an inkjet printhead. The printhead when assembled includes at least two nozzle banks and is operative for printing one particular color ink or other liquid and each nozzlebank includes plural nozzles. The printhead is operational in a printer to print raster rows so that at least one raster row is printed using ink drops deposited at respective different pixel locations on the raster row by respective different nozzles on each of the at least two nozzle banks. The method includes (a) characterizing a drop size parameter for predetermined nozzles of each of the nozzle banks; (b) identifying for each of plural raster rows the respective different nozzles on each of the at least two nozzle banks that would be used to print the respective raster row; (c) identifying a size characteristic associated with each of the plural raster rows using a predetermined computer algorithm without printing the raster rows; and (d) determining in accordance with a criterion and data derived from size characteristic identified in step (c) whether or not the at least two nozzle banks are an acceptable match.
