Abstract
A device for printing a web moving in a direction (YB), wherein ink jets print on the web a printing width across its direction (YB) of advancement while traversing a printing station. The printing station includes one or more printer heads that produce ink jets over a footprint width which is narrower than the intended printing width over the web. One or more shaping elements bestow on the web traversing the printing station a V-shape so that the web is at least locally oriented oblique to the linear array of nozzles that project the ink. The ink from the printer head(s) is thus printed over the intended printing width of the web.
Claims15
A method for ink jet printing a web moving in a direction (YB) wherein the web travels through a printing station to be printed over a printing width across the direction (YB) by ink jets projected from a linear array of nozzles over a footprint width narrower than the printing width, wherein the web is at least locally oriented oblique to the linear array of nozzles that project the ink, whereby ink from the ink-jets projected over the footprint width is printed over the printing width of the web.
A device for ink-jet printing a web moving in a direction (YB) wherein the web is printed over a printing width across the direction (YB), the device including:
- a printing station to be traversed by the web to be printed, the printing station including at least one printer head with a linear array of nozzles producing ink-jets over a footprint width narrower than the printing width, and
- at least one element to at least locally orient the web oblique to the linear array of nozzles that project the ink whereby ink from the ink-jets projected over the footprint width is printed over the printing width of the web.
