摘要： In a color printing system the printer driver automatically obtains local characteristic information, such as countries, cities, languages, etc., stored in the OS of the host computer. The printer driver or the image forming apparatus color-converts the input data into output data, which reflects the color preference of the specific region where the image forming apparatus is installed, by using the look-up table corresponding to the local characteristic information obtained by the printer driver. Accordingly, the color preference of the specific region, in which the image forming apparatus is installed, is set more quickly and easily without requiring a complicated structure. The system includes a host computer to store local characteristic information of a region where an apparatus is installed, a printer driver to store look-up tables according to the local characteristic information, to select a look-up table corresponding to the local characteristic information obtained from the host computer, and to convert input data into output data representing a color corresponding to a color preference of a specific region by using the selected look-up table, and an image forming apparatus which is connected to the host computer so as to receive and print the output data, which is color-converted by the printer driver.

摘要： A color data conversion apparatus and method. The color data conversion apparatus includes a K ratio calculator for outputting a K ratio that is calculated using entered color data; a K ratio adjuster for adjusting the calculated K ratio, which is output from the K ratio calculator, in reference to gamut boundary descriptors (GBDs) corresponding to a K ratio and outputting the adjusted K ratio as a final K ratio; and a CMY ratio calculator for calculating C, M, and Y ratios based on the final K ratio. When converting the entered color data to the CMYK data, the calculated K ratio can be adjusted to the K ratio printable by use of the K GBDs. Accordingly, the printing apparatus can substantially print according to the calculated K ratio and thus the degradation of the printing quality can be avoided.
