20110075163 | SYSTEMS AND METHODS OF COLOR CONVERSION WITH GRAY VALUES - Methods and systems herein provide for the color conversion of image data with various levels of gray values, such as text. Such color conversion includes generating a CMYK conversion model by defining a gray region in the perceptual color space of the image data to convert the gray values of the gray region to a range of K values during CMYK color conversion of the image data and segmenting chroma values in a color lookup table that maps perceptual color values to CMYK color values. Lightness values in the color lookup table are adjusted using a perceptual model (e.g., a Heimholtz-Kohlrausch Effect model) based on the segmented chroma values to substantially maintain a lightness relationship between the gray values of the image data and the remaining color values of the image data. The image data is the converted to a CMYK color space using the generated CMYK conversion model. | 03-31-2011 |
20110109943 | OUTPUTTING GRAY COLOR VALUES IN COLOR-MANAGED CMYK TO CMYK COLOR CONVERSIONS BASED ON INPUT GRAY COLOR VALUES - Methods and systems herein provide for CMYK color conversion of input image data while preserving K color values during the conversion process. A color management module is operable to convert input image data from one color space to a CMYK color space. For example, the color management module may convert the image data of one device operating in a CMYK color space to a CMYK color space of another device. In doing so, the color management module preserves or maintains the K color values of the input image data during the CMYK to CMYK color conversion. The color management module may implement such by modifying input and output ICC profiles and interpolating the perceptual lightness values of the input ICC profile within the output lookup table. | 05-12-2011 |

Longmont CO USAANM Li; HongAACI SuperiorAAST COAACO USAAGP Li; Hong Superior CO USAANM Walp; Jason C.AACI LouisvilleAAST COAACO USAAGP Walp; Jason C. Louisville CO US - Force K processing is presented to replace gray color values of input data with only levels of black ink/toner when color management is not specified in the print job. A system converts input data of a print job to a CMYK color space of a printer by processing a lookup table of color values for the color space of the input data based on a detected color space of the input data to identify gray color values of the lookup table. The system also determines that these gray color values produce an output in the CMYK color space of the printer that includes one or more of cyan, magenta, and yellow color components. The system replaces the gray color values with black color values and corresponds the black color values of the lookup table with gray color values of the input data for conversion of the input data. | 01-17-2013 |
