Abstract
A system for printing on a substrate can comprise a conveyor that is configured to move the substrate along a substrate movement axis. The system can further comprise at least one print head array. Each print head array has a plurality of print heads, each print head having a respective orientation axis. The plurality of print heads can have at least a first print head and a second print head, wherein the orientation axis of the first print head is angularly offset from the orientation axis of the second print head. The first print head can be offset from the second print head along the substrate movement axis.
Claims20
A method comprising:
- moving a substrate along a substrate movement axis, wherein the substrate has a surface having a first portion and a second portion, wherein the first portion or a plane tangential thereto is angularly offset from the second portion or a plane tangential thereto,
- printing on the first portion and the second portion of the surface of the substrate with at least one print head during a single pass of the substrate along the movement axis,
- wherein each print head of the at least one print head comprises a first plurality of nozzles spaced along a respective nozzle row axis,
- wherein the respective nozzle row axis of each print head of the at least one print head is oriented at an acute angle relative to the substrate movement axis, and
- wherein a plane, that includes the respective nozzle row axis of each print head of the at least one print head and is parallel to the substrate movement axis, is spaced from the substrate movement axis.
