Abstract
Examples include a method for mitigating decap in a printing system that comprises nozzles, in which printing data associated to a graphical representation and that comprise pixel data points are received. Some data points are associated with a corresponding nozzle and a corresponding direction of movement and at least one specific data point is associated with a specific direction of movement and a specific nozzle which has a decap time below a first predetermined threshold. The received printing data is modified by displacing the printing data of the specific data point in a direction opposite to the specific direction of movement in order to compensate for the decap time.
Claims15
A method for mitigating decap in a printing system, the printing system comprising a plurality of nozzles, the method comprising:
- receiving printing data associated to a graphical representation, the printing data comprising pixel data points;
- associating at least some data points of the pixel data points with a corresponding nozzle and with a corresponding direction of movement, and whereby at least a specific data point of the at least some data points is associated with a specific direction of movement and with a specific nozzle, the specific nozzle having a decap time below a first predetermined threshold;
- and
- modifying the received printing data by displacing the printing data of the specific data point in a direction corresponding to a direction opposite to the specific direction of movement in order to compensate for the decap time.
A printing system controller comprising a processor, a storage medium coupled to the processor and an instruction set to cooperate with the processor and the storage medium to:
- receive printing data associated to a graphical representation, the printing data comprising representation data points;
- associate at least some data points of the representation data points with a corresponding nozzle and with a corresponding direction of movement,
- associate at least a specific data point of the at least some data points with a specific direction of movement and with a specific nozzle, the specific nozzle having a decap time below a first predetermined threshold;
- and
- operate an image processing module to modify the received printing data by displacing the printing data of the specific data point in a direction corresponding to a direction opposite to the specific direction of movement.
A computer-readable storage medium storing instructions that, when executed, direct a processor to perform a method comprising:
- receiving printing data associated to a representation, the printing data comprising representation data points;
- associating at least a specific data point of the representation data points with a specific direction of movement and with a specific nozzle, the specific nozzle having a decap time below a first predetermined threshold;
- and
- compensating for the decap time below the first predetermined threshold by displacing the printing data of the specific data point in a direction corresponding to a direction opposite to the specific direction of movement in order to compensate for the decap time.
