    • A multi-pass imaging system and method provides for duplex documents and multiple color images with variable information to be printed by re-entering a substrate into a same tower system, employing a split roller design, for generating subsequent portions of a printed image. When a webbed substrate is fed into a tower, a first one in each of multiple pairs of rollers moves the substrate past a first set of printheads for generating a first portion of the printed image. The substrate is then re-entered into the tower, and a second one in each of the multiple pairs of rollers moves the substrate past a subsequent set of printheads for generating a subsequent portion of the printed image. Each of the multiple pairs of rollers comprise independently operating dual rollers on a single shaft.
    • 多通道成像系统和方法通过采用分裂辊设计,为印刷图像的后续部分提供用于通过将基板重新进入同一塔架系统来印刷可变信息的双面文件和多色图像。 当蹼状基材进料到塔中时,多对辊中的每一对中的第一个辊移动基板通过第一组打印头,以产生印刷图像的第一部分。 然后将衬底重新进入塔中,并且多对辊中的每一对中的第二个辊移动衬底通过随后的一组打印头,以产生印刷图像的后续部分。 多对辊中的每一对在单个轴上包括独立操作的双辊。
