    • The disclosed embodiments include a method to compensate for defective printer nozzles included in printer nozzles used to print an image on a medium. The method includes detecting defective printer nozzles, and initiating a print job in a print mode. The print job can include image data used to print the image on the medium in accordance with a print mask that maps the printer nozzles to pixel locations of the image. The method further includes modifying the print mask or the image data to print using the image data with printer nozzles that may be complementary to the defective printer nozzles, and printing the image on the medium in accordance with the print mode and the modified print mask or the modified image data.
    • 所公开的实施例包括补偿包括在用于在介质上打印图像的打印机喷嘴中的有缺陷的打印机喷嘴的方法。 该方法包括检测有缺陷的打印机喷嘴,并以打印模式启动打印作业。 打印作业可以包括用于根据将打印机喷嘴映射到图像的像素位置的打印掩模在介质上打印图像的图像数据。 该方法进一步包括修改打印掩模或图像数据以使用具有与缺陷打印机喷嘴互补的打印机喷嘴的图像数据进行打印,并且根据打印模式和修改的打印掩模将图像打印在介质上,或者 修改后的图像数据。

    • Disclosed are a printer vacuum tables, and corresponding systems and methods for their use, in which the printer vacuum tables include multiple zones to apply vacuum, to hold a variety of media types and thicknesses within a given flatness range, to allow high definition printing. The vacuum zones run in the print direction, and each can be controlled for vacuum on and off. In an illustrative embodiment, the vacuum zones include one or more vacuum zones that are fixed with respect to a printer vacuum table surface, and one or more variable vacuum zones that are movable with respect to the printer vacuum table surface. One or more of the vacuum zones can be turned off if the print media does not cover the zone, such as to prevent leakage, and to provide more consistent vacuum hold down, regardless of media size or width.
    • 公开了一种打印机真空表及其相应的系统及其使用方法,其中打印机真空台包括多个区以施加真空,以将多种介质类型和厚度保持在给定的平坦度内 范围内,以便进行高清打印。 真空区域沿打印方向运行,每个区域都可以控制真空的开启和关闭。 在说明性实施例中,真空区域包括相对于打印机真空台表面固定的一个或多个真空区域,以及相对于打印机真空台表面可移动的一个或多个可变真空区域。 如果打印介质没有覆盖该区域,例如以防止泄漏,并且提供更一致的真空保持,则无论介质尺寸或宽度如何,都可关闭一个或多个真空区域。

    • Edge hold down (EHD) systems are described herein that enable high print quality to be achieved more consistently, particularly when using substrates that are rigid or include one or more defects. Each EHD system includes a tensioned band for holding down an edge of a substrate as it passes through a printer assembly without impacting the print area. The tensioned band can be affixed between an entry tension assembly and an exit tension assembly disposed downstream of the entry tension assembly in the media feed direction. The tensioned band holds the substrate substantially flat against a transfer belt during printing by applying pressure to the surface of the substrate. The tensioned band generally contacts the surface of the substrate substantially proximate to an outer edge that is parallel to the media feed direction.
    • 本文描述了边缘保持(EHD)系统,其能够更一致地实现高打印质量,特别是当使用刚性或包括一个或多个缺陷的基板时。 每个EHD系统包括张紧带,用于在基材穿过打印机组件时保持其边缘而不影响打印区域。 张紧带可以在入口张紧组件和设置在入口张紧组件下游的出口张紧组件之间沿着介质供给方向固定。 张紧带通过对基底表面施加压力而在打印期间将基底保持为基本平坦地抵靠转印带。 张紧的带通常接触基板的表面,基本上接近平行于介质馈送方向的外边缘。
