Abstract
Operations of printing systems are disclosed. According to examples, a deposition sequence for depositing printing fluids onto a substrate location is dynamically controlled. Sub-groups of nozzles in nozzle arrays are selected according to the deposition sequence.
Claims18
A printing system, comprising:
- a printhead receiving assembly to receive a printhead including a first nozzle array arrangement for jetting a first printing fluid, a second nozzle array arrangement for jetting a second printing fluid, and a third nozzle array arrangement for jetting a third printing fluid;
- and
- a processor to operate the first nozzle array arrangement, the second nozzle array arrangement, and the third nozzle array arrangement to deposit the first and the second printing fluids onto a swath of a substrate within a same pass of the printhead over the swath, and deposit the third printing fluid onto the swath within a different pass of the printhead over the swath after the substrate has advanced in relation to the printhead in a substrate advance direction perpendicular to a pass direction of the printhead.
A non-transitory computer-readable medium storing code executable by a processor to:
- operate a first nozzle arrangement of a printhead jetting a first printing fluid and a second nozzle arrangement of the printhead jetting a second printing fluid to deposit the first and the second printing fluids onto a swath of a substrate within a same pass of the printhead over the swath;
- and
- operate a third nozzle arrangement of the printhead jetting a third printing fluid to deposit the third printing fluid onto the swath within a different pass over the swath after the substrate has advanced in relation to the printhead in a substrate advance direction perpendicular to a pass direction of the printhead.
A method comprising:
- operating a printhead for depositing ink and treatment on a substrate location according to a deposition sequence, the printhead including a first nozzle array arrangement for ejecting a first fluid onto a substrate location, and a second nozzle array arrangement for ejecting a second fluid onto the substrate location, comprising:
- determining a deposition sequence for depositing the first and second fluids on the substrate location;
- and
- operating a sub-group of nozzles in the first nozzle array arrangement and a sub-group of nozzles in the second treatment nozzle array arrangement according to the deposition sequence,
- wherein the first and second fluids are quasi-simultaneously deposited onto a swath of the substrate within a same pass of the printhead over the swath.
