摘要： An improved ink jet printhead comprising upper and lower substrates that are mated and bonded together with a thick film insulative layer sandwiched therebetween. One surface of the upper substrate has etched therein one or more grooves and a recess which when mated with the lower substrate will serve as capillary filled ink channels and ink supply manifold, respectively. The grooves are open at one end and closed at the other. The open ends serve as nozzles. The manifold recess is adjacent the grooved closed ends. Each channel has a heating element located upstream of the nozzle. The heating elements are selectively addressable by input signals representing digitized data signals to produce ink vapor bubbles. The growth and collapse of the bubbles expel ink droplets from the nozzles and propel them to a recording medium. A recess patterned in the thick layer provides a flow path for the ink from the manifold to the channels by enabling the ink to flow around the closed ends of the channels and increase the flow area to the heating elements. Thus, the heating elements lie at the distal end of the recesses so that a vertical wall of elongated recess prevents air ingestion while it increases the ink channel flow area and increases refill time, resulting in an increase in bubble generation rate.
摘要翻译： 一种改进的喷墨打印头，其包括上下基板，其与夹在其间的厚膜绝缘层配合并结合在一起。 上基板的一个表面在其中蚀刻有一个或多个凹槽和与下基板配合的凹槽，分别用作毛细管填充的墨水通道和墨水供应歧管。 槽在一端敞开，另一端封闭。 开口端作为喷嘴。 歧管凹槽与凹槽的封闭端相邻。 每个通道具有位于喷嘴上游的加热元件。 加热元件可以通过表示数字化数据信号的输入信号来选择寻址，以产生油墨蒸气泡。 气泡的生长和坍塌从喷嘴中排出墨滴并推动它们到记录介质上。 在厚层中图案化的凹槽通过使墨水能够围绕通道的封闭端流动并且增加到加热元件的流动面积而提供用于从歧管到通道的墨水的流动路径。 因此，加热元件位于凹部的远端，使得细长凹槽的垂直壁防止空气摄取，同时增加墨通道流动面积并增加再填充时间，导致气泡产生速率的增加。

摘要： A color ink jet printing device capable of substantially reduced intercolor bleeding includes an ink jet printer having at least one printhead and at least three separate ink supplies in communication with the printhead. A first ink supply contains a slow drying black ink. A second ink supply contains a fast drying black ink. A third ink supply contains a fast drying non-black color ink. Prior to printing, black image potions are determined. The black portions are printed using a pixel priming process, a border substitution process or a combination thereof to reduce intercolor bleed. The pixel priming process first prints a quartertone or halftone pattern using fast drying black ink, followed by subsequent whole tone printing superposed on the primed black image area using a slow drying black ink. The border substitution process analyzes a neighboring matrix of pixels surrounding each black pixel, preferably at least a 5.times.5 matrix, to determine if color pixels other than black are present. If so, that black pixel is printed using the fast drying black ink to reduce intercolor bleed. Otherwise, the black pixel is printed using slow drying black ink. This printing may be further improved by checkerboarding the black image portions. This involves printing a partial tone checkerboard pattern in a first pass and printing a complementary checkerboard pattern on a second pass to provide a whole tone of the image portions.

摘要： An ink jet method and apparatus including circuitry for controlling lateral deflection of an ink column before drops are formed. A deflection mechanism used to deflect the column comprises two electrode portions spaced on opposed sides of the column. By control of the voltages applied to the electrode portions the angle of ink column deflection is made proportional to a control voltage applied to the portions. This proportionality facilitates control over column scanning to insure proper ink drop placement on the ink jet recording medium.

摘要： An intelligent printer driver is provided. The printer driver includes a printer detector which detects characteristics of a printer to be used to generate a document unless the driver is specific to a known printer. A document detector detects content of the document to be printed. A matching module compares the characteristics of the printer and the content of the document and determines whether the printer and content of the document are mismatched. A notification module notifies a user if the printer and the document are mismatched and a recommendation module generates recommendations to the user as to modifications of the document which are determined to be mismatched by the printer. The user may then select a preview document shown on the monitor, may request further modifications to the document, may print the document without any modifications, or may abort the print process.

摘要： The present invention provides a method for processing color image data for printing on an inkjet printer to reduce intercolor bleeding in an image recorded on a receiving medium. The method receives a target pixel comprising multiple separation pixels, wherein each separation is associated with a separate color plane and has at least three states, a first state corresponding to depositing no ink drops, a second state corresponding to depositing one ink drop, and a third state corresponding to depositing more than one ink drop. The method further includes determining if the target pixel is within a black border region near a black/color interface or within a color border region near a black/color interface. If the target pixel is within a black border region, the method replaces the target pixel with a black border output pixel derived from a black pixel modification pattern identifying an arrangement of separation pixels to deposit approximately one drop for each pixel location in the black pixel modification pattern. Similarly, if the target pixel is within a color border region near a black/color interface, the method replaces the target pixel with a color border pixel derived from a color pixel modification pattern identifying an arrangement of separation pixels for each non-black color plane that deposits approximately one drop for each pixel location.
摘要翻译： 本发明提供一种处理用于在喷墨打印机上打印的彩色图像数据的方法，以减少记录在接收介质上的图像中的色间渗色。 该方法接收包括多个分离像素的目标像素，其中每个分离与单独的彩色平面相关联并且具有至少三种状态，对应于不沉积墨滴的第一状态，对应于沉积一个墨滴的第二状态，以及 第三状态对应于沉积多于一个的墨滴。 该方法还包括确定目标像素是否在黑色/彩色界面附近的黑色边框区域内或黑色/彩色界面附近的颜色边界区域内。 如果目标像素在黑色边框区域内，则该方法用从识别分离像素的布置的黑色像素修改图案导出的黑色边框输出像素替换目标像素，以在黑色像素修改中为每个像素位置存储大约一个色阶 模式。 类似地，如果目标像素在黑色/彩色界面附近的颜色边界区域内，则该方法将用于识别每个非黑色平面的分离像素排列的彩色像素修改图案导出的颜色边框像素替换目标像素 它为每个像素位置存放大约一滴。

摘要： A wide array ink jet printhead for use in an ink jet printing device and being capable of propelling ink to create a line on a recording medium in the device. The printhead includes a plurality of adjacent and generally linear printheads each having a first and second end ink jet. A plurality of electrodes are in communication with the ink jets. A microprocessor controls the electrodes to selectively provide a current signal representing digitalized data to the electrodes. When the digitalized signal is intended to create a line on the recording medium more than one printhead wide, the ink jets on adjacent printheads forming the line are initialized from a first end ink jet to a second end ink jet on a first printhead and in a reverse order from a second end ink jet to a first end ink jet on the adjacent printhead, the sequences commencing substantially simultaneously on each printhead.
