摘要： A printhead uses large and small drop ejectors to achieve efficient gray scale printing. The printhead is arranged with a close packed configuration of alternating large and small nozzles positioned to maximize coverage while minimizing the volume of ejected ink. The printhead may be operated in a single pass mode or dual pass mode. In the single pass mode, complete coverage is effected by rippling through the odd numbered jets first and then rippling through the even numbered jets. The position of the small spots from the even numbered jets can be adjusted to maximize coverage and counteract offset between nozzle centers. Printheads with different size nozzles can also be operated by a staggered firing method using dual passes to offset spots in the scan direction by shifting the printhead between passes or alternating between groups of large and small nozzles. Further improvements to image quality can be realized by shifting the spots in the direction perpendicular to the scanning direction by tilting the printhead or offsetting the nozzles with respect to the ink channels on the printhead.

摘要翻译： 打印头使用大而小的墨滴喷射器来实现高效的灰度打印。 打印头布置成具有交替的大和小喷嘴的紧密堆积构造，其被定位成最大化覆盖范围，同时最小化喷射墨的体积。 打印头可以在单程模式或双通道模式下操作。 在单程模式中，完全覆盖通过首先通过奇数射流波纹，然后通过偶数喷射波纹来实现。 可以调整来自偶数喷嘴的小点的位置，以最大化覆盖范围并抵消喷嘴中心之间的偏移。 具有不同尺寸喷嘴的打印头也可以通过交错的点火方法来操作，使用双程通过在扫描方向上偏移打印头，使打印头在通过之间移动或在大喷嘴和小喷嘴组之间交替。 通过倾斜打印头或相对于打印头上的墨水通道偏移喷嘴，可以通过使垂直于扫描方向的方向上的点移动来实现对图像质量的进一步改进。

摘要： An ink jet printhead includes an ink reservoir having an fluid inlet for receiving ink, a top portion, and a bottom portion. A channel plate structure that is etched from silicon defines a plurality of microchannels in fluid communication with the reservoir for directing ink from the reservoir. Support structure is provided near the top portion of the reservoir and extending within the reservoir. The support structure is formed to divide the reservoir into at least a pair of reservoir regions and to provide support to the channel plate structure while permitting substantially unobstructed fluid flow to all of the channels at the bottom portion of the reservoir. In addition to forming printheads for ink jet printers, the invention may be applied to other microchannel fluidic devices.

摘要： A method and system for processing image data in an image processing device for a plurality of pixel positions within a plurality of scanlines. The method and system includes storing a starting stamp value and a plurality of delta stamp values for the scanline. The stored values being used to generate a pixel stamp value for an input pixel in the scanline, by adding a starting value or previous pixel stamp value and the stored delta stamp value for the input pixel. Further includes receiving an input pixel intensity value for the input pixel and determining an output pixel intensity value. Subsequently, if the output pixel intensity value for the input pixel is equal to a value for a dot or hole the delta stamp values for at least one pixel having a location previous or subsequent to the input pixel can be updated.

摘要： Methods and systems for performing threshold stamping are disclosed. A pixel intensity value for a first pixel may be determined. A pixel value for the first pixel may be retrieved from a memory location corresponding to the first pixel. A threshold delta value may then be determined based on the pixel value and added to a base threshold value to produce a threshold value. If the pixel intensity value exceeds the threshold value, a plurality of pixel values corresponding to a plurality of pixels may be updated. The plurality of pixels may include the first pixel and one or more second pixels. Otherwise, the pixel value for the first pixel may be updated.

摘要： A system cuts media printed with phase change ink in a manner that reduces the ink debris produced by cutting solidified ink. The system includes a heater configured to heat phase change ink on the media moving through the heater to a temperature at which the ink is malleable, the temperature being above room temperature and below a temperature at which phase change ink melts, and a cutter configured to receive the media after the media has been heated by the heater and to cut the media. The blade of the cutter may also be heated to facilitate media cutting with a reduced likelihood of solid ink debris being generated.

摘要： A method for image correction compensates for a defective inkjet in a printhead by distributing compensation values to other image data locations in an image data memory. The method includes searching image data stored in an image data array to detect one or more edges in the image data, modifying an ordered sequence search to search for compensation candidate positions in image data array positions proximate a defective inkjet image data array position in response to an edge being detected proximate to the defective inkjet image data array position, searching the image data array positions proximate the defective inkjet image data array position in accordance with the modified ordered sequence, identifying a compensation candidate image data array position to which a compensation image value can be moved, and moving the compensation image value to the identified compensation candidate image data array position.
