  • Publication number: 20220247888
    Abstract: A system and method enable determining a total colorant limit for printing images. The system includes memory which stores instructions for: determining a grain value for each of a set of printed patches printed on a first print media, the grain value being based upon a visual contrast sensitivity function computed for the respective patch, the set of printed patches including patches printed on the print media at different total colorant values; determining a total colorant limit for the first print media, as a function of the total colorant values and corresponding grain values for the printed patches in the set, wherein the total colorant limit is a total colorant value which corresponds to a grain value which does not exceed a threshold grain value for the first print media. A processor executes the instructions.

  • Patent number: 11376839
    Abstract: Examples of the preferred embodiments use an ink quantity metric (e.g., lightness L*, darkness, image density, line width) of printed content to determine thickness of fountain solution applied by a fountain solution applicator on an imaging member surface and/or determine image forming device real-time image forming modifications for subsequent printings. For example, in real-time during the printing of a print job, a sensor (e.g., spectrometer) may measure the ink quantity metric of the current printing on print substrate. Based on this measurement of printed content output from the image forming device, the image forming device may adjust image forming (e.g., fountain solution deposition flow rate) to reach or maintain a preferred fountain solution thickness on the imaging member surface for subsequent (e.g., next) printings of the print job.

  • Patent number: 11320737
    Abstract: According to aspects of the embodiments, there is provided a method of measuring the amount of fountain solution using a hot wire anemometer. Fountain solution thickness is measured using the flow rate of vaporized fountain solution and comparing to baseline air only flow rate. The vaporized measurement is correlated with the baseline utilizing specific heat, density and enthalpy values and keeping velocity of fluid constant. Changes in the measurement will then be related to the specific heat, density and enthalpy. Density can be back calculated to yield volume and knowing the area of the image being printed give a real time thickness value.

  • Patent number: 11293873
    Abstract: The present disclosure relates to using color calibration to improve and increase the accuracy of interpreting color-sensitive results from test strips made of substrates like paper. This is accomplished via a diagnostic test unit including a substrate, at least one region on the substrate, a reagent placed within the region to react, and a series of color legends on the substrate. Different reagent samples may be placed on the separate regions of a substrate for testing. An imaging device is used to capture the reaction results. More precise readings can be obtained by comparing the reaction results to the color legends to determine the measured property of the analyte.

  • Publication number: 20220032533
    Abstract: A direct-to-object printer is configured to adjust a pixel density of a portion of contone image data for an image to be printed on a surface of a tapered object. The controller of the printer also filters the contone image data with a stochastic halftone filer to produce binary image data for the image to be printed on the tapered object. The adjustment in the pixel density for the portion of the image to be printed on the portion of the object having a circumference that is different than another portion of the surface at the uppermost portion of the image produces a more uniform appearance in the resulting printed image.

  • Publication number: 20210402755
    Abstract: Examples of the preferred embodiments use an ink quantity metric (e.g., lightness L*, darkness, image density, line width) of printed content to determine thickness of fountain solution applied by a fountain solution applicator on an imaging member surface and/or determine image forming device real-time image forming modifications for subsequent printings. For example, in real-time during the printing of a print job, a sensor (e.g., spectrometer) may measure the ink quantity metric of the current printing on print substrate. Based on this measurement of printed content output from the image forming device, the image forming device may adjust image forming (e.g., fountain solution deposition flow rate) to reach or maintain a preferred fountain solution thickness on the imaging member surface for subsequent (e.g., next) printings of the print job.

  • Patent number: 9975327
    Abstract: A direct-to-object printer includes a plurality of imaging devices that generates image data of an object secured in a holder before the holder and the object pass a plurality of printheads for printing an ink image on the object. A controller receives the image data and converts it to an object profile. The controller operates ejectors in the printheads with reference to the object profile to attenuate inconsistent ink image density and ink image distortion.

  • Patent number: 9955041
    Abstract: A method of operating a three-dimensional object printer to form printed images on a surface of an object with increased color resolution includes generating a plurality of low-precision tone reproduction curves (TRCs) from a plurality of high-precision color conversion entries that are modified by a plurality of values in a one-to-one correspondence to the TRCs. The method further comprises generating modified contone image and halftone image data for each plane using one of the low-precision TRCs and forming the image from multiple printed layers of ink corresponding to the plurality of planes.

  • Patent number: 9561644
    Abstract: 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.
