20100134550 | PRINTING CONTROL APPARATUS, PRINTING SYSTEM, AND PRINTING CONTROL PROGRAM - A printing control apparatus includes a printing unit which designates a color material amount set corresponding to a designated index by referring to a lookup table defining a correspondence between the index that specifies a target value that is information indicating a color of an object and a target color material amount set that is the color material amount set of which approximation to the target value is maximized. The target color material amount set is a second color material amount set obtained by predicting a first color material amount set based on a predetermined prediction model so that the approximation is maximized while the used amount of the low-concentration color material is suppressed and by using the first color material amount set as an initial value of the predetermined prediction model so that the approximation is maximized while the used amount of the high-concentration color material is suppressed. | 06-03-2010 |
20110069334 | PRINTING APPARATUS AND PRINTING METHOD - A printing apparatus includes an obtaining unit, a printing unit and a consideration request unit. The obtaining unit is configured and arranged to obtain image data of an object and target spectral characteristics information relating to the object. The printing unit is configured and arranged to print an image of the object according to the image data, and to print at least one color patch using the target spectral characteristics information while the color patch is associated with the image. The consideration request unit is configured and arranged to transmit a consideration request for printing of the image based on a comparison result between the target spectral characteristics information and spectral characteristics information obtained by color measurement of the color patch that was printed | 03-24-2011 |
20110075171 | PRINTING APPARATUS AND CALIBRATION METHOD - A printing apparatus is adapted to form a printed image by forming ink dots based on an ink amount specified for each of a plurality of pixels forming image data. The determination unit is configured to analyze the image data and to determine at least one color patch to be printed based on a result of the analysis. The patch printing unit is configured to print the color patch. The color measurement unit is configured to perform color measurement on the color patch to obtain a color value indicated in the color patch. The correction data creation unit is configured to create correction data using the color value obtained by the color measurement unit. The printing unit is configured to form the ink dots based on the ink amount that has been corrected based on the correction data. | 03-31-2011 |
20110279833 | PRINTER AND PRINTING METHOD - A printer performs calibration in which a reference primary color ink is mixed with at least one additional primary color ink to approximate a predetermined target primary color. The printer includes an acquisition section, a predicting section, an optimizing section and a printing unit. The acquisition section acquires spectral reflectances of the reference primary color ink printed on a base, the additional primary color ink printed on the base, and the base. The predicting section calculates predicted spectral reflectance of a mixture of the primary color inks by dividing a product of the spectral reflectances of the primary color inks by the spectral reflectance of the base raised to the power obtained by subtracting 1 from a total number of the inks. The optimizing section optimizes an ink-amount set of the mixture so that the predicted spectral reflectance is approximated to spectral reflectance of the target primary color. | 11-17-2011 |

20090161187 | OUTPUT DATA GENERATING IMAGE PROCESSING - An image processing device generates output data used when an image displayed on a display device is to be output by an output device. The image processing device includes an output execution instruction input unit and a color space converter. The output execution instruction input unit inputs an instruction to execute image output via the output device. The color space converter carries out a first conversion process and a second conversion process. The first conversion process converts first device-dependent image data that expresses an image in a first device-dependent color space handled by the display device into device-independent image data that expresses the image in a device-independent color space. The second conversion process converts the device-independent image data into second device-dependent image data as the output data that expresses the image in a second device-dependent color space handled by the output device. The color space converter initiates the first conversion process prior to an input of an instruction to execute output by the output execution instruction input unit. The color space converter initiates the second conversion process in response to the input of an instruction to execute output by the output execution instruction unit. | 06-25-2009 |
