摘要： A system for selectively shifting the phase of drop charging along the array of ink jets of a continuous ink jet printer by producing a replicate signal of the drop stimulation signal; selectively shifting the phase of the replicate signal to provide a phase control signal; synchronizing a media feed tachometer signal to the phase control signal to produce a print enable signal; and controlling address of the charge electrodes with the print enable signal. The system further includes a selection mode wherein drop charge phase can be made random by selecting synchronization with the media feed tachometer signal.

摘要： A method for avoiding drop charge switching errors in continuous ink jet printing of the kind using stimulation to regulate ink drop break-off of a linear array of ink streams. The method includes the steps of: controlling ink drop stimulation so that the phase distribution of drop break-off along the length of the ink stream array remains stable in time and charging stimulated drop streams in at least two different groups during at least two different address periods which are offset in phase so that all drop streams are addressed during a drop break-off condition.

摘要： A method for controlling an electrophotographic printing system to print digital image data for an image region. An image region database stores data characterizing a plurality of reference image regions, each reference image region having one or more associated system control parameters that are appropriate for use in printing the reference image region. The system control parameters can include parameters related to correcting color registration errors. The image region to be printed is compared with the reference image regions in the image region database, and a similar reference image region is selected. The image region is printed using the system control parameters associated with the selected similar reference image region.

摘要： A printing system for printing on a print medium is disclosed. A first linehead is disposed opposite a first side of the print medium. The first linehead defines print zones where a liquid is deposited onto the first side of the print medium. A plurality of transport rollers are disposed adjacent to the second side of the print medium. At least one transport roller is aligned with one of the one or more print zones of the first linehead. A vacuum manifold is disposed opposite the second side of the print medium. The vacuum manifold is aligned with the aligned transport roller and outputs a vacuum force that operates on the second side of the print medium to deflect the print medium causing an increase in the wrap angle of the print medium around the aligned transport roller.

摘要： A method for printing on a moving print medium in a printing system is disclosed. The method includes providing a linehead defining one or more print zones. A plurality of transport rollers are provided, wherein at least one transport roller is disposed opposite the linehead, adjacent to the second side of the print medium, and aligned with one of the print zones. A vacuum assembly is disposed opposite the second side of the print medium and includes a vacuum manifold aligned with the aligned transport roller. The print medium is moved through the printing system and a vacuum force operates on the print medium such that at least a portion of the print medium is deflected thereby increasing a wrap angle of the moving print medium around the aligned transport roller. Liquid is jetted from the linehead onto the print medium to form a print.

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.
