Abstract: A printing system is disclosed. The printing system includes at least one physical memory device to store compensation logic and one or more processors coupled with the at least one physical memory device to execute the compensation logic to receive measurement data corresponding to a print medium printed with a plurality of non-functioning pel forming elements, a plurality of functioning pel forming elements and a plurality of tint levels; wherein adjacent ones of the plurality of functioning pel forming elements print with compensated halftone designs applied to pels adjacent to the plurality of non-functioning pel forming elements, associate measurement data with the plurality of non-functioning pel forming elements, corresponding compensated halftone designs and the plurality of tint levels and determine optimal compensation by selecting the compensated halftone designs that have corresponding measurement data values closest to compensation target values for each of the plurality of tint levels.

Abstract: Systems and methods are provided for reporting printhead conditions. One embodiment is a system that includes a user interface, a display, and a controller configured to present a Graphical User Interface (GUI) via the display. The GUI includes a first area depicting an array of printheads. Each printhead of the array is represented by a first visual indicator that signifies a frequency of printhead conditions detected at that printhead over a period of time. In response to receiving a selection of at least one of the printheads via the user interface, the controller presents a second area of the GUI via the display. The second area depicts locations of printhead conditions detected at the selection over the period of time. Each of the locations is represented by a second visual indicator that signifies a frequency of printhead conditions detected at that location over the period of time.
