Abstract
To allow for printing on print media with pre-formed wrinkles, a printer is provided, which comprises a print applicator which prints on a portion of a print medium at a print zone; a transporter for moving the print medium with respect to the print applicator in a first direction; and a print medium suction applicator comprising: a plurality of suction chambers, wherein at least one suction chamber faces a print zone, and at least one other suction chamber is arranged upstream and/or downstream of the suction chamber facing the print zone in the first direction, characterized in that the print medium suction applicator further comprises a suction reduction unit configured to selectively prevent or reduce suction in the at least one other suction chamber.

A printer comprising:
- a print applicator configured to print on a portion of a print medium at a print zone;
- a transporter f configured to move the print medium with respect to the print applicator in a first direction;
- and
- a print medium suction applicator comprising a plurality of suction chambers,
- wherein at least one suction chamber of the plurality of suction chambers faces the print zone, and
- wherein at least one other suction chamber of the plurality of suction chambers is arranged upstream and/or downstream of the print zone facing suction chamber in the first direction, and
- wherein the print medium suction applicator comprises a suction reduction unit configured to selectively prevent or reduce suction in the at least one other suction chamber.
A method for printing on a wrinkled print medium, the method comprising:
- transporting an inherently wrinkled print medium through a print zone facing a print applicator;
- applying suction to the inherently wrinkled print medium in the print zone;
- and
- preventing suction in at least one buffer zone adjacent to and upstream and/or downstream of the print zone, so that the inherently wrinkled print medium is locally flattened in the print zone, forcing pre-formed wrinkles into the at least one buffer zone.
A printer comprising:
- a print applicator comprising at least one printhead arranged to define a print zone, wherein the at least one printhead is configured to print on a portion of a print medium in the print zone;
- a transporter configured to move the print medium through the print zone with respect to the print applicator in a first direction;
- and
- a print medium suction applicator comprising a plurality of suction chambers,
- wherein at least one suction chamber of the plurality of suction chambers faces the print zone, and
- wherein at least one other suction chamber is arranged upstream and/or downstream of the at least one suction chamber facing the print zone in the first direction, and
- wherein the print medium suction applicator comprises a suction reduction unit configured to selectively prevent or reduce suction in the at least one other suction chamber.
