摘要： A method for correcting color registration errors for a print job including one or more documents having a plurality of color planes. A color registration error model is used to predict a color registration error value for a document as a function of ink coverage characteristics for the document, wherein the color registration error model is a parametric model having one or more parameters. An image plane correction value is determined based on the predicted color registration error, and the document is printed using the determined image plane correction value.

摘要： A method for correcting color registration errors for a color printer that prints color image data on a continuous web of media. A color registration error model is used to predict a color registration error value for a particular in-track position as a function of ink coverage characteristics for an image region including the particular in-track position, wherein the color registration error model is a parametric model having one or more parameters. An image plane correction value is determined based on the predicted color registration error, and the color image data for the particular in-track position is printed using the determined image data correction values.

摘要： Reducing waste in a digital printing system (200) includes moving media (214) through a web transport system (205) at a first speed. A first job is printed on the print media and a downstream finishing device (203) in a first configuration acts on the media. The web slows to a second speed prior the end of the first job and the finishing device changes to a second configuration after the first job has passed. A time to complete changing from the first to the second configuration is estimated and a time for a first section of the media containing the end of the first job to arrive at the finishing device is estimated. A second job is printed on the media prior to completion of the change based on the estimated time to completion.

摘要： A continuous inkjet printhead includes a jetting module, a fluid system, and a controller. The jetting module includes an array of nozzles. The fluid system includes a liquid source and a pressure control device. The liquid source includes a liquid and is connected in fluid communication with the jetting module. The controller is in electrical communication with the pressure control device of the fluid system and is configured to provide a first signal to the pressure control device to cause the liquid to be ejected as liquid streams through the nozzles of the array at a first pressure sufficient to create a stream of print-selectable drops. The controller is configured to provide a second signal to the pressure control device to cause the liquid to be ejected as liquid streams through the nozzles of the array at a second pressure with the second pressure being less than the first pressure. The controller is configured to provide the first signal to the pressure control device after a period of time.
