Abstract
A printing system for printing images formed of pixels on a substrate, the system comprising a print system arranged where printheads traverse a substrate, the print system arranged to receive a sequence of print actuation requests in order to print each pixel of an image upon the substrate, the print system having an acceptable rate for the sequence of print actuation requests, the system configured whereby if presented with an actuation period of less than the minimum actuation period then the presented rate of print actuation requests is adjusted by altering the actuation event and/or the discarding of stripe data, to minimise print defects.
Claims20
A print system for receiving actuation requests having an arrangement of print nozzles driven by a succession of actuation events with a need for a minimum actuation period between the actuation events, the arrangement including:
- a means to queue actuation requests so that an actuation event can continue to be performed after the minimum actuation period has occurred;
- and
- a means to monitor the queue such that if the queue becomes longer than a defined discard threshold then the arrangement is configured to discard actuation requests from the queue and discard some stripe data.
A method of operating a print system which receives actuation requests and stripe data having an arrangement of print nozzles driven by a succession of actuation events with a need for a minimum actuation period between the actuation events, the arrangement including:
- a means to queue actuation requests so that an actuation event can continue to be performed after the minimum actuation period has occurred;
- and
- a means to monitor the queue such that if the queue becomes longer than a defined discard threshold then the arrangement is configured to discard actuation requests from the queue and discard some stripe data.
