摘要： A system is disclosed. The system comprises one or more print controllers to generate print interrupt instructions in response to receiving a web splice signal indicating that a web splice on a web print medium has been detected, wherein the print interrupt instructions indicate a first side sheet image and a second side sheet image within a print job to pause prior to stopping printing, wherein the print interrupt instructions comprise gap instructions to open a first printhead gap at the first print engine and to open a second printhead gap at the second print engine, control printing of the first side sheet image on a first side of a web at a first print engine based on the print interrupt instructions, control printing of the second side sheet image to a second side of the web at a second print engine based on the print interrupt instructions, wherein the print interrupt instructions are generated based on a determination of an interrupted first side sheet image to be paused prior to opening the first printhead gap and a determination of an interrupted second side sheet image to be paused prior to opening the second printhead gap.

摘要： Systems and methods are provided for enhanced flushing of printing systems. One embodiment is a printing system that includes an ink flushing controller. The ink flushing controller is able to identify an overlap region wherein nozzles at adjacent printheads of a marking engine overlap along a widthwise direction, to detect primary nozzles that print image data within the overlap region, and to detect overlap nozzles that do not have firing instructions to eject ink within the overlap region. The ink flushing controller is further able to analyze nozzle firing data for each overlap nozzle to determine inactive firing spans for each overlap nozzle, and in response to determining that an inactive firing span for an overlap nozzle exceeds a threshold, to generate a firing instruction directing the overlap nozzle to eject ink.

摘要： A method is disclosed. The method includes receiving one or more images of bitmap data applied to a print medium as print medium image data, register the print medium image data to the bitmap data, detecting one or more candidate defects based on whether a difference between the print medium image data at a location and the bitmap data at the location exceeds a predetermined threshold, detecting one or more defects among the candidate defects and transmitting information about the one or more candidate defects classified as defects.
