Abstract: A method of increasing data flow to a printing device includes, with a first raster image processor, converting a document into a first bitmap having a first dot density and representing a black color plane of the document; with a second raster image processor, converting the document into a second bitmap at a second dot density that is a relatively lower dot density than that of the first bitmap, the second bitmap representing other color planes of the document; and transmitting data of the first and second bitmaps to a printing device for printing to a print medium.
Abstract translation: 增加到打印设备的数据流的方法包括：利用第一光栅图像处理器将文档转换成具有第一点密度并且表示文档的黑色平面的第一位图; 利用第二光栅图像处理器，以比第一位图的点密度低的第二点密度将文档转换成第二位图，第二位图表示文档的其他色平面; 以及将第一和第二位图的数据发送到打印装置以打印到打印介质。

Abstract: In an example, an apparatus is described that includes a vision system and an image correction module. The vision system captures an image of a multi-lane print output. The image correction module receives the image of the multi-lane print output from the vision system and calculates a calibration to image data from which the multi-lane output is printed. The calibration minimizes visual variations between the multi-lane print output and a reference image.
