Abstract: A method of printing onto a planar box substrate used for assembling a box having predetermined box dimensions. The method includes the steps of: determining box dimensions based on the planar box substrate; retrieving generic instructions for image content to be printed on the box substrate; preparing box-specific transformations using the generic instructions and the box dimensions; applying the box-specific transformations on design components to generate image content portions commensurate with image content regions; generating image data based on the image content portions; and printing onto the box substrate using the image data.

Abstract: A method of adjusting a level of liquid to be deposited on a print media includes providing an image processing system. Image data for a page of a print job and information regarding a printing system to be used to deposit the liquid on the print media during a printing operation is provided to the image processing system. The image data for the page of the print job is converted into a bitmap appropriate for analysis of risk of excessive inking related print defects using the image processing system. The overall risk score is determined to be acceptable or unacceptable. The bitmap is released for printing when the overall risk score is acceptable. The image data for the print job page is modified when the overall risk score is unacceptable.

Abstract: A method of controlling print density in a printing system includes gathering first data from a first sensor; gathering second data from a second sensor; comparing the first data to the second data; if the first data correlates to the second data no action is required; if the first data deviates from the second data; determine a confidence level for each sensor; identify the sensor with the lowest confidence level; and take corrective action.

Abstract: A printing system using multiple printheads maintains color consistency between the printheads by printing a first color patch (102) with a first color with a plurality of printheads (30) at a first pressure and with a first pixel fill coverage. A second color patch (104) is printed with the first color with the plurality of printheads at a second pressure with the first pixel fill coverage. The print density of the first patch and the second patch is measured for each of the plurality of printheads and the print density for each of the plurality of printheads is compared. A pressure for each of the plurality of printheads is adjusted to compensate for differences in density between the first patch and the second patch for each of the printheads.

Abstract: The present invention addresses the reformatting of a digital “ready to print” data file into a continuous tone (32 or 24 bit) file whereby discrete values in the tone range are uniquely assigned to specific binary combinations. The purpose for this transform is to facilitate further manipulation of preprocessed data. One application of the present invention is to exist as a critical piece of proofing workflow for a technology that reduces continuous tone data into a binary form representing droplet selection prior to output.

Abstract: A method of determining substrate and ink compatibility includes providing a test pattern having a range of ink loading levels and including test features corresponding to at least one of text and graphics; identifying a substrate; identifying an ink set; printing the test pattern on the identified substrate using the identified ink set; selecting an ink loading level for at least one of the at least one of text and graphics using the test pattern; and generating a tone scale transformation for one or more ink colors of the identified ink set using the selected ink loading level for at least one of the at least one of text and graphics, the selected ink loading level for the at least one of the at least one of text and graphics being dependent on the identified substrate.

Abstract: A system and method are provided for determining ink jet printing system parameters by selecting an appropriate linearizing transformation for application to images to be printed on a printing system for a specific substrate. These transformations can be any transformation capable of being applied in graduated increments and having a corresponding incremental visual influence on the printed output. The present invention allows the user to determine multiple parameters for the printer, including for example, tone scale correction, determination of upper ink limits, amount of under color removal, and allows the user to identify the proper ink level for optimum quality of graphics and/or text printing.

Abstract: The present invention provides for the creation and use of a non-linearized, paper specific, digital workflow independent color profile which can be used to create proofs based on the raw output data of the source process. Such a profile would have the advantage of not having to have account for the intermediate workflow steps such as linearization, color correction, sharpening, ink limiting, color separation, dithering or color transformation because the gamut mapping would utilize the discrete output tones of the resulting data sent to the source device.

Abstract: A system and method are provided for linearizing the tone scale of individual colors in a multi-color printing system, by deriving a prescribed tone scale of individual colors in a single or multi-color printing system. Full linear ink gradations are printed on multiple substrates, and a linearization table is generated with multiple points for each of the multiple substrates and/or ink gradations. A polynomial curve is fitted to the points of each linearization table to generate polynomial curves. At least one point in the polynomial curves is selected, that shows high variation from one curve to a next curve, and coefficients of a group of polynomial curves are plotted as functions of the value of the at least one point. The range of prediction can be as narrow or as broad as an application requires. Finally, a prescribed tone scale table is derived from the polynomial curves and the at least one point.

Abstract: The present invention addresses the quantification of a printed tone scale for each individual color in a printing system, developing a linear tone scale derived in an independent color space and referenced from the shade of the unprinted substrate. The present invention determines the threshold for excessive ink coverage of a printing system on a specified substrate. This determination is based on a subjective evaluation of acceptable thresholds for bleed, cockle, show through, and image density. The method works in conjunction with a predefined test pattern printed on the specified substrate at fixed printing parameters, such as speed, dryer temperature, and web tension. This invention also includes an ability to limit the ink of each independent color in the system as a fraction of the total upper ink limit. Furthermore, this invention allows calibration of the tone scale of each color in the system using the color of the paper as a reference point.

Abstract: The methods for processing an image from data for imaging on a digital output device include inputting data made of numerous image pixels with values representative of the pixel intensity for imaging to a digital output device, employing a threshold highlight value into the digital output device, and applying data transformation to the data for imaging using the threshold highlight value to form transformed data. The methods end by forming a representation from the transformed data. The representation is a value representative of the pixel intensity greater than or equal to 1.
