摘要： In one embodiment of the invention, an inkjet printer selectively energizes ink ejection elements in a scanning printhead such that the top nozzles of the printhead do not always print the first line of text in a scan. In one embodiment, this is accomplished by occasionally aligning the bottommost nozzle in the printhead with the bottom of the last full line of text to be printed during the scan. The alignment of the printhead with respect to the lines of text to be printed is varied from page to page or varied at other intervals so that the top nozzles and bottom nozzles are used about equally. This will also cause more uniform wear of the middle nozzles. The more uniform wearing of the nozzles and ink ejection elements extends the life of the printhead. In inkjet printers using a black ink printhead which has a wider printing swath than one or more color ink printheads in the same scanning carriage, a new printing technique makes use of the nozzles in the wider printhead which extend beyond the shorter printhead when both printheads are being used during color printing.
摘要翻译： 在本发明的一个实施例中，喷墨打印机选择性地激励扫描打印头中的喷墨元件，使得打印头的顶部喷嘴不总是在扫描中打印第一行文本。 在一个实施例中，这是通过在扫描期间偶尔将打印头中的最下面的喷嘴与要打印的最后一行文本的底部偶尔对准来实现的。 打印头相对于要打印的文本线的对准在一页到另一页之间变化或者以其他间隔变化，使得顶部喷嘴和底部喷嘴大致相等地使用。 这也将导致中间喷嘴更均匀的磨损。 喷嘴和喷墨元件的更均匀的磨损延长了打印头的使用寿命。 在使用黑色墨水打印头的喷墨打印机中，其具有比同一扫描托架中的一个或多个彩色墨水打印头更宽的打印条纹，新的打印技术利用在两个打印头是两个打印头时延伸超过较短打印头的较宽打印头中的喷嘴 在彩色打印期间使用。

摘要： At least two different pixel densities are used for different printing devices--such as inkjet pens--that operate concurrently, or different printing steps that proceed concurrently, to produce respective image swaths in a single, pixel-based printing machine. The different print devices or steps produce image swaths of respective different swath heights. In one form of the invention, the taller-swath-height printing device operates at lower pixel density, spreading its colorant over a greater area while printing-medium advance keeps pace with operation of the shallower-swath-height printing device. This procedure allows more drying and penetrating time for the colorant applied by the taller-swath device, thereby improving print attributes such as bleed, offset, cockle, curl, overall drying time and throughput. In another form of the invention the taller-swath device operates at higher pixel density, providing physical and temporal separation of colorant application from the two printing devices--to avoid adverse interfering effects between reactive inks.
摘要翻译： 至少两个不同的像素密度用于不同的打印装置，例如同时进行的喷墨笔，或同时进行的不同的打印步骤，以在单个基于像素的印刷机中产生相应的图像条。 不同的打印设备或步骤产生各个不同的扫描高度的图像条纹。 在本发明的一种形式中，较高的扫描高度打印设备以更低的像素密度工作，在较大的区域上扩展其着色剂，同时打印介质的前进跟随较浅的扫描高度打印设备的操作。 该方法允许由较高条带装置施加的着色剂的更多的干燥和穿透时间，从而改善打印属性，例如渗色，偏移，起翘，卷曲，总干燥时间和生产量。 在本发明的另一种形式中，较高的条带装置以更高的像素密度工作，从而提供着色剂应用与两个印刷装置的物理和时间分离，以避免反应性墨水之间的不利干扰效应。

摘要： An inkjet printer is disclosed with mixed print resolution capabilities. The printed dots have a high resolution monochrome component such as black and lower resolution components such as cyan, magenta and yellow. For increased throughput, a higher resolution black printhead has a wider swath. Various alignments between the printheads and printed dots are disclosed. In one embodiment, the top edges of the smaller color printheads are aligned in a scanning carriage at or near the top of the wider black printhead. In other embodiments, the bottom edges of the smaller color printheads are aligned at or near the bottom of the wider black printhead. In another embodiment, the small color printheads are centered with the wider black printhead.

摘要： At least two different printmasks are used for different printing devices--such as inkjet pens--that operate concurrently, or different printing steps that proceed concurrently, to produce respective image swaths in a single, pixel-based printing machine. In one form of the invention, the different printing devices produce different respective pixel-row pitches (related to resolution) on a printing medium, and the different printmasks help to minimize adverse patterning effects that result from interaction of the different pitches with dot-placement errors. The different pitches on the print medium may be provided through different pitches of marking devices (for example, the number of inkjet nozzles per unit distance along a pen) or in other ways. In another form of the invention the different printing devices are provided with different respective liquid-base colorants, to mark in different colors on a printing medium, and the different masks facilitate physical separation of the different colorants to promote drying. Earlier-applied colorants have more time to dry and penetrate before later adjacent or superposed application of other colorants.

摘要： In the preferred form, a scanning carriage in a color inkjet printer houses a high resolution printhead for black (or monochrome) printing and one or more lower resolution printheads for color printing. The nozzle arrangements, paper feed increments, and ink drop firing frequency for the black printhead and color printhead(s) are selected to provide various alignments between the larger color ink dots and the smaller black ink dots to achieve maximum ink coverage with a minimum of ink or to achieve additional color shades.

摘要： In one embodiment of the invention, a scanning carriage in a color inkjet printer houses three identical color pens for printing cyan, magenta, and yellow. A separate array of nozzles is associated with each color ink. The nozzle arrays are such that they scan over the same print area of the medium during a single scan. To prevent the wet ink from one color swath being deposited over or bleeding into the wet ink from another color swath during the same scan, only a section of each nozzle array is used for printing during a single scan such that wet ink of two different colors cannot overlap during a single scan. This technique reduces ink bleed between colors as well as paper cockle. In another embodiment, a single tricolor pen is used where a single nozzle plate contains three nozzle arrays, one for each color. A section of each nozzle array is used during a single scan, as described above, to prevent wet ink of two different colors from overlapping during a single scan.
