Abstract: A method of printing from a fixed inkjet printhead having a plurality of ink planes. The method includes the steps of: feeding a print medium past the printhead in a media feed direction, the media feed direction defining relative upstream and downstream sides of the printhead; printing an image onto the print medium, the image being defined by image data; and printing a keep-wet pattern onto the print medium from each ink plane of the printhead, the keep-wet pattern being defined by a plurality of dots printed at a frequency sufficient to maintain hydration of each nozzle in the printhead. A first keep-wet pattern from a first ink plane is printed at a higher frequency than a second keep-wet pattern from a second ink plane, the first ink plane being furthest upstream in the printhead.

Abstract: A method of generating print data for an inkjet printhead having a plurality of ink planes. The method includes the steps of: receiving image data for a print job in a printer controller; retrieving keep-wet pattern data for each ink plane of the printhead, the retrieved keep-wet pattern data being determined using one or more input parameters; generating first print data for each ink plane in the printer controller based on the received image data; merging the first print data with the keep-wet pattern data to provide second print data for each ink plane; and sending the second print data from the printer controller to the printhead, thereby causing the printhead to print an image together with a keep-wet pattern. The keep-wet pattern is defined by a plurality of dots printed at a frequency sufficient to maintain hydration of each nozzle in the printhead.
Abstract translation: 一种生成具有多个墨平面的喷墨打印头的打印数据的方法。 该方法包括以下步骤：在打印机控制器中接收打印作业的图像数据; 检索打印头的每个墨平面的保湿图案数据，使用一个或多个输入参数来确定检索到的保湿图案数据; 基于接收到的图像数据，生成打印机控制器中的每个墨平面的第一打印数据; 将第一打印数据与保持湿图案数据合并以提供每个墨平面的第二打印数据; 并将第二打印数据从打印机控制器发送到打印头，从而使打印头与保持湿图案一起打印图像。 保湿图案由以足以维持打印头中每个喷嘴的水合的频率打印的多个点限定。

Abstract: An inkjet printhead includes an elongate fluid manifold having a base which includes a truss structure. The truss structure has webs extending between opposite chords, wherein a plurality of openings between the webs and the chords define fluid outlets. One or more printhead chips are attached to the webs of the truss structure with each printhead chip receiving printing fluid from a plurality of the fluid outlets.
