摘要： A method for operating a three-dimensional object printer compensates for inoperative ejectors. The method identifies image data values associated with an inoperative ejector that stored in a memory with other image data values for a three-dimensional object to be printed by the three-dimensional object printer. The method replaces the image data values associated with the inoperative ejector with image data values associated with an operative ejector that correspond to a material that is different than a material ejected by the inoperative ejector and operates a plurality of ejectors with reference to the other image data values and the replaced image data values to enable the operative ejector to eject drops of the material that is different than the material ejected by the inoperative ejector into the three-dimensional object at positions where the inoperative ejector would have ejected material.

摘要： A printer compensates for variations in ejected material drop volumes occurring during production of the layers for the formation of an object in a three-dimensional printer. The printer includes an optical sensor that generates topographical and measurement data of each layer of the object after each layer is printed. Differences in height between columns of material being formed by the ejectors in the printhead are identified with reference to the data produced by the sensor and raster data used to operate the printhead are modified adjust the formation of a next layer in the object.

摘要： A method of operating a printer includes identifying a region of a print medium located between marks formed by a first plurality of inkjets in the printer and an edge of the print medium. The printer activates a second plurality of inkjets to print ink drops into the region during a printing operation. The method enables full-bleed or near full-bleed printing for different media sizes.

摘要： An MFD is disclosed. For example, the MFD includes a color printhead to dispense color printing fluid, an enhancement printhead to dispense a three-dimensional (3D) print material, a processor and a non-transitory computer-readable medium storing a plurality of instructions. The instructions when executed by the processor cause the processor to perform operations that include printing a two-dimensional (2D) image on a substrate and printing a 3D object on the 2D image printed on the substrate such that colors of the 2D image provide a desired color for a desired portion of the 3D object.

摘要： A method of printer operation identifies inkjets to operate in each scanline to eject sneeze drops or, in an alternative approach, identifies the cross-process direction scanlines within a page to be printed by the printer where each inkjet ejects sneeze drops. The methods use a binary grayscale code counter that generates a sequence of binary grayscale code numbers and every other output of the sequence is bit reversed to spread the sneeze drops over the pages of the printer output so the sneeze drops are not perceptible to a human observer.

摘要： A three-dimensional object printer has a controller that operates pluralities of ejectors ejecting drops of different materials having different colors, at least one color of which is white, to produce objects with different levels of color saturation. The controller operates the pluralities of ejectors with reference to a function of a sum of an average number of drops per voxel in each layer, a target value of an average number of drops per voxel of colorants other than white in each layer, and a distance from a closest surface of the object for each material ejected by the ejectors. At a predetermined distance from a closest surface and greater, the controller operates the pluralities of ejectors to form voxels in layers of the object with only clear and white drops. At distances less than the predetermined distance, the number of clear drops increases and the number of white drops decreases.

摘要： A method and system compensates for malfunctioning inkjets using contone values for an image prior to the contone values being rendered for printing of the image. The method generates contone values for color space components in a compensation level for each malfunctioning inkjet. The contone values in each compensation level are modified with reference to a profile selected for each malfunctioning inkjet and with reference to the modification of the contone values in the vicinity of each malfunctioning with the compensative level. The modified contone values of each compensation level are merged with the contone values in the vicinity of each malfunctioning inkjet. The contone values are then rendered and used to operate inkjets for forming an ink image on an ink receiving member.
