Multipassing stands for the multiple passing over of an image content to be printed. When using multipassing processes, the individual pixel rows of a print image are built up by repeatedly passing over them with as different nozzles as possible.

In a very simplified way, multipassing can be described with the help of a checkerboard. A group of nozzles passing over the print image initially only covers the white fields with ink. A group of other nozzles following later applies ink to the black fields.

The process is used to achieve the desired ink coverage and to disguise a possible application characteristic of the print heads. In addition, cooperating rows of nozzles compensate for the output of different droplet masses and reduce the load on the printheads.

Most inkjet printers achieve acceptable print quality only through the use of multipassing processes.

The CLUSTERJET servers enable multipassing even when the passes required for the intended ink coverage are made by several different clusters.

This is the case, for example, when a printed material transported by a conveyor belt is passed by several stations, each of which applies only part of the intended ink.
