HIGH-SPEED MULTI-COLOR PRINTING

摘要

A multi-resolution imaging device (10) for a high-speed multi-color printer includes at least one high-resolution sensor array (23), wherein an output of the high-resolution sensor array is transmitted to a controller (19); at least one low-resolution sensor array (24); wherein the controller calculates a correction for stitch; wherein the controller, based on the calculated correction, adjusts a timing of image data provided to individual print elements comprising print stations (12) to aligned an output of the print elements; and wherein the low-resolution sensor array provides full page viewing.

1. A system for high-speed multi-color printing comprising:
a first print station having a plurality of print elements each of which prints a swath on a print media that prints a first image plane; wherein adjacent swaths are stitched together at stitch locations; a first linear sensor having at least two first high-resolution sensor arrays aligned with stitch locations and at least one first low-resolution sensor array; wherein the two first high-resolution sensor arrays are non-continuous; transmitting an output of the first high-resolution sensor arrays to a controller; wherein the controller calculates a stitch correction based on the first high-resolution image for the first print station; wherein the controller, based on the calculated correction, adjusts at least one of a timing or a selection of print elements of image data and provided to printing dots on the first print station to align an output of the printed dots; a second print station having a plurality of print elements each of which prints a swath on a print media that prints a second image plane; wherein adjacent swaths are stitched together at stitch locations; a second linear sensor having at least two second high-resolution sensor arrays aligned with stitch locations of the second print station and at least one second low-resolution sensor array; wherein the two second high-resolution sensor arrays are non-continuous; transmitting an output of the second high-resolution sensor arrays to the controller; wherein the controller calculates a second image plane stitch correction based on the second high-resolution image for the second print station; and wherein the controller, based on the calculated correction, adjusts at least one of a timing or a selection of print elements of image data provided to printing dots on the second print station to align an output of the printed dots.
