Abstract: An inkjet printer includes a waste ink treatment system and a humidification chamber to separate waste ink produced by a printhead maintenance station into solid ink pigment particles and a solvent stream and use the solvent stream to maintain inkjets in the printheads of the inkjet printer in operational status. The waste ink treatment system mixes the waste ink with a metal salt to precipitate the solid ink pigment particles out of the waste ink. The solvent stream remaining after the precipitation of the pigment particles is humidified and directed to air baffles positioned on opposite sides of each printhead in every other printhead module in the process direction. A kit is provided to retroactively modify an existing inkjet printer to treat the waste ink and use the solvent stream to maintain the operational status of the inkjets in the printheads of the inkjet printer.

Abstract: A method of manufacturing a three-dimensional object operates components in an additive manufacturing system with reference to a difference between quantifications identified for different properties of at least two materials in a same layer. The method enables the layer to be formed with compensation for the differences in the quantifications of the properties of the two materials.

Abstract: A method of inkjet printer operation produces a sneeze pattern having a uniform sneeze pattern portion and a tapered area portion within the uniform sneeze pattern to operate inkjets in the printer to eject ink drops within an image area of media sheets passing through the printer to maintain the operational status of the inkjets. A dynamic threshold is applied to a portion of an uniform sneeze pattern to produce the tapered area within the uniform sneeze pattern. The dynamic threshold is changed as a function of distance between a pixel in the portion of the uniform sneeze pattern and the closest edge of an image area of the media sheet on which the tapered area of the sneeze pattern is to be printed. A second threshold can also be changed to alter a volume of ink associated with a pixel in the tapered area within the uniform sneeze pattern.

Abstract: An optical gloss meter above an imaging member surface measures fountain solution surface gloss on the imaging member surface in real-time during a printing operation. The measured gloss corresponds to a thickness of the fountain solution layer and may be used in a feedback loop to actively control fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during a printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

Abstract: A method of operating a printer separates the image content data for a sheet in a print job into multiple color separations and operates a digital air curtain between the printhead modules that print the multiple color separations. Image data of the printed color separations are used to adjust operating parameters for the digital air curtain.

Abstract: A method for evaluating curing in an ink composition comprises depositing an ink composition on the surface of an object via a direct-to-object inkjet printing system to form a film thereon, the ink composition comprising a photoinitiator capable of initiating a free radical polymerization process in the ink composition upon the absorption of light to cure the deposited film; exposing, in-situ, the deposited film to light generated by a first source of light under conditions which initiate the free radical polymerization process to cure the deposited film; exposing, in-situ, the cured film to light generated by a second source of light under conditions which induce light absorption by unreacted photoinitiator in the cured film; measuring the absorbance of the cured film; and determining a degree of cure in the cured film from the measured absorbance and predetermined calibration data.

Abstract: A surface treatment system includes a holder configured to secure an object within the holder and a surface treatment device that is configured to treat a surface of the object within the holder with two types of surface treatments. The device is capable of producing a plasma or a flame at its nozzle for surface treatment. By controlling the materials supplied to the device and the way in which is operated, either a flame or plasma is produced. Thus, the surface treatment system is capable of treating a wide range of materials for printing by a direct-to-object printer.
