20110096365 | Print Interface - Method of generating a CIElab to Neugebauer Primary area coverages interface for a print system, comprising selecting area coverages of Neugebauer Primaries and printing corresponding patches, measuring the CIE XYZ coordinates of the patches, converting the CIE XYZ coordinates to corresponding CIE Lab coordinates, and relating the CIE Lab coordinates to the NPacs. | 04-28-2011 |
20110292433 | PRINT WORKFLOW MANAGEMENT - A method for managing print workflow performed by a physical computing system includes, with an add-on application executed by the physical computing system, interfacing with a printing-capable application executed by the physical computing system; with the add-on application, interfacing with hardware components of a printing device; and with the add-on application, providing additional printing related functionality to the printing-capable application. | 12-01-2011 |
20120057781 | METHOD AND SYSTEM TO DETERMINE WHETHER AN IMAGE INCLUDES SPATIAL ADJUSTMENTS - The present disclosure provides a computer-implemented method of identifying spatial image modifications. The method includes receiving a original image and a adjusted image. The method also includes identifying a first subset of pixels comprising pixels in the original image that have a same first color value. The method also includes determining whether a second subset of pixels in the adjusted image all have a same second color value, wherein the second subset of pixels spatially correspond with the first subset of pixels. A spatial adjustment is identified if the second subset of pixels do not all have the same second color value. | 03-08-2012 |
20130076778 | COLOR LOOKUP TABLE SMOOTHING EMPLOYING NODE ADJUSTMENT PROPAGATION - Color lookup table smoothing employs propagation of a portion of an adjustment of a modified node to an unmodified node of a color lookup table (CLUT). | 03-28-2013 |
20130101328 | SYSTEM AND METHOD FOR PRE-PRINT INK USE ESTIMATION - An image representation of an image and printing specifications describing how the image is to be printed may be accepted at a device. A predicted ink drop count may be calculated by a processor in the device using the image representation and a printer imaging step, the printer imaging step to convert image data into printer data. A predicted ink use value may be calculated by processor based on the predicted ink drop count, predicted ink drop weights, the image representation (e.g., a histogram) and the printing specifications. Actual ink use during a printing operation may be measured. | 04-25-2013 |
20150298474 | METHODS FOR PRINTING WITH A PRINTHEAD - A method for printing, comprising: obtaining an imaging matrix, in which each row or each column of cells is associated with at least a nozzle of a printhead, and in which each cell contains an initial value of a parameter which is related to an amount of ink to be deposited on the print medium; dividing the imaging matrix into at least two subsets of cells, such that each cell of the matrix belongs to one of said subsets; associating with each subset of cells a conversion function; obtaining a converted imaging matrix by applying to the initial value in each cell the function that corresponds to the subset to which the cell belongs; and printing using said converted imaging matrix. | 10-22-2015 |
20150324996 | IMAGE PROCESSING FOR PRINTING - Image processing for printing comprises identifying regions of an input image having characteristics of distinct printing requirements; classifying each pixel within each identified region based on the characteristic of the identified region; applying a colour mapping to each pixel according to the classification of the pixel to optimize each color mapping in accordance with at least one of plurality of attributes. | 11-12-2015 |
20150365565 | TO GENERATE A PRINT SPECIFICATION COLOR SEPARATION LOOK-UP TABLE - In a method to generate a print specification color separation look-up table, a device color space is sampled to provide at least one sampled value. The sampled value is transformed to a device independent color space. The transformed sampled value is gamut mapped using a source color gamut and a color separation color gamut to provide a color separation value. The gamut mapping is performed in an expansion mode and a compression mode. | 12-17-2015 |
