摘要： A marking device is controlled to mark a media sheet with halftone dots selected from a set of image halftone dot representations. The marking device is controlled to mark a monitored surface with halftone dots selected from a set of control halftone dot representations to form test patches of different nominal marking densities. Measured marking densities are acquired using a density sensor for the test patches marked on the monitored surface. The set of control halftone dot representations is updated based on the measured marking densities and the nominal marking densities.

摘要： An electrostatographic reproduction machine that includes an image bearing member means for forming a latent image having image areas and background areas; at least a development housing containing charged carrier beads, charged fragments of the charged carrier beads which undesirably cause image deletions, and charged toner particles for developing image areas to form a toner image; means for transferring the toner image to a sheet of paper, and means for fusing the toner image to the sheet of paper. Importantly the reproduction machine includes a method and control system for reducing halftone image deletions in future halftone images. The method and control system include means for distinguishing latent solid image patterns from latent halftone image patterns; means for counting a number of solid image patterns developed with toner on the image bearing surface; means for providing an electrostatic halftone stress image pattern for electrostatically forming and developing on the image bearing surface; and means for forming and developing a number of the halftone stress image patterns on the image bearing surface, under certain machine operating conditions, so as to attract charged fragments of the charged carrier beads out of the development housing, thereby reducing deletions that would otherwise be undesirably caused by the carrier bead fragments in future halftone toner images

摘要： A user of an image forming device selects from among a plurality of pre-stored color rendition dictionaries (CRDs) in order that a set of system process parameter setpoints associated with that CRD may be referenced to bias and/or skew an available color gamut in the direction of a particular nominally out-of-gamut color which the user wishes to produce in a color image output by the image forming device. A capability is included in a color image forming device store and/or update multiple sets of special process parameter setpoints defining a plurality of CRDs each of which may be identified and associated with a specific color in order that requests to print out-of-gamut colors may be satisfied routinely as exceptions to a nominal gamut based on a nominal set of stored setpoints when a CRD is selected and the setpoints associated with that CRD are input for reference by the color image forming device on a temporary basis.

摘要： A method for calibrating in situ a plurality of printheads in an imaging device has been developed. Firing signals operate a plurality of printheads to form ink test patterns on an image receiving member. Reflectance measurements of light reflected from the test patterns and optical density measurements for a portion of the patterns formed by only one printhead in the plurality of printheads are used to adjust the firing signals and enable the printheads to print within a predetermined range about an average reflectance value and a predetermined optical density.
