Abstract: A print configuration system will receive, from a first sensing modality, a first message indicating that a user has entered a first region where a print device is located. The system will access a profile for the user to identify a first configuration task, and it will cause the print device to perform the first configuration task. The system will later receive, from a second sensing modality that is different from the first sensing modality, a second message indicating that the user has entered a second region. The second region includes the print device and is a subset of the first region. In response to receiving the second message, the system will cause the print device to perform a second task that is different from the first configuration task.

Abstract: A system and method provide for automated evaluation of reference point pairs. For each of a set of reference point pairs in an input color space, a straight line connecting the reference points is sampled to generate a set of sampled points. Each of the set of sampled points in the input color space is converted to a sampled point in an output color space. For each of a set of color separations in the output color space, discontinuities are identified, based on the set of sampled points in the output color space. Candidate reference point pairs are identified in the set of reference point pairs for which at least one discontinuity is identified. The candidate reference point pairs can be validated by printing test sweeps, which are each derived from a respective set of sampled points in the output color space, and identifying contour artifacts in the printed test sweeps.

Abstract: According to exemplary methods, a processor of a printing device determines color values out of a first colorant combination using marking materials for standard colorants and marking materials for one or more extended gamut colors. The extended gamut color has colorants other than the standard colorants. Responsive to the first colorant combination including color values for each of a pair of two complementary colors, the processor calculates a second colorant combination that produces the same human-perceivable color as the first colorant combination. The second colorant combination includes only one color of the pair of two complementary colors. The printing device produces output using the second colorant combination for the standard colorants and the extended gamut color.

For example, the method includes receiving a source profile of a color image, converting the source profile into a device specific color space profile, converting the device specific color space profile into a grayscale device specific color space profile that only has black separation values for each output node using a destination profile that is device specific and printing the color image in a grayscale using the grayscale device specific color profile that reproduces a tone of each color of the source profile of the color image.

Abstract: Method, system, and graphical user interface for enabling optimal colorant job programming. A graphical user interface displays a plurality of gamut mode selectable features. One or more of the gamut mode selectable features can be selected for image processing of an image. A graphical image can be displayed within the next of the user interface based on image processing of the image, and in response to selection of a gamut mode selectable feature. The resulting displayed graphical image with the user interface can demonstrate to a user the benefit of utilizing additional colorant on the image particular pixels in the graphical image, which can benefit from the additional colorant.

Abstract: A system and method for color management of a color printer for correcting color drift using a single unified calibration tone reproduction curve (TRC). The unified calibration TRC may be applied to destination profiles for all halftones during printing. When printer drift occurs, only the unified calibration TRC is recalibrated to create a new unified calibration TRC which is subsequently applied to the destination profiles for all color halftones during printing to correct the color output of the color printer.

Abstract: A system and method for automatic selection of at least one spot color to be processed by a digital image press includes identifying process colorants to determine principal and extended gamuts thereof. Spot color recipes of the principal and extended gamuts are retrieved from a spot color library, along with a set of attributes corresponding to use of colorants by the digital image press. For each spot color recipe, a combined attribute score is calculated relating to the principal gamut and the extended gamut, spot color recipe of the extended gamut or principal gamut is then identified for use based upon which has the higher combined attribute score. The spot color library is then updated in accordance with the identified recipe for production of each spot color. Print jobs are then output with the appropriate spot color recipe automatically selected.

Abstract: Methods and systems for super resolution encoding. A matching pattern can be encoded with respect to an original pattern to generate a matching function for converting a screen into an IOT screen. Then, an operation can be implemented for accounting for a disturbance that causes a change in gray value that includes a minimal error while remaining close to the original pattern. The gray value is then mapped to the matching pattern via the matching function to convert the screen into the IOT screen and thereby minimize the effects of lossy compression and data variations caused by the disturbance.

Abstract: Methods and devices calibrate a printing device to develop a single calibration tone reproduction curve associated with a first halftone state for the printing device, and calculate a primary color profile for the first halftone state and secondary color profiles for the secondary halftone states available with the printing device based on a previously calculated relationship between the first halftone state and the secondary halftone states. Subsequently, these methods and devices receive a print job and such methods identify the secondary halftone state of the print job. With this, the methods and devices can identify a secondary color profile from the secondary color profiles that corresponds to the secondary halftone state and raster image process the print job using the secondary color profile to produce rasterized output. Then, these methods and devices print the rasterized output on print media using a print engine of the printing device.
