Patent ID: 8411101

Claim:
A preview data generating apparatus configured to generate preview data, which is used to display a preview image representing an image to be printed on a recording medium, in reflection of a color of the recording medium, comprising: a base color input unit configured to input a base color being the color of the recording medium; a print data input unit configured to input print data in a printable format, which is used to print the image; a data conversion unit configured to convert the print data into a displayable format suitable for a display device; and a base color incorporated data generating unit to generate the preview data representing the image to be printed by incorporating the displayable-formatted data and the base color, wherein the base color incorporated data generating unit generates white preview data representing whiteness of the preview image; wherein the print data input unit inputs scale values for a plurality of colors of pixels included in the print data, the plurality of colors including white; wherein the data conversion unit converts the scale values for the plurality of colors of pixels inputted by the print data input unit into scale values for the colors of pixels in the displayable format; wherein the preview data generated by the base color incorporated data generating unit is configured with R, G, B color components, which are red, green, and blue respectively; wherein the preview data generating apparatus further comprises an extractor unit to extract scale values of C, M, Y colors, which are cyan, magenta, and yellow respectively, from the print data to convert into CMY data; and wherein the base color incorporated data generating unit generates colored preview data, which represents a multi-colored preview image, by: subtracting the extracted scale value of the C color from the scale value of the R color component in the white preview data; subtracting the extracted scale value of the Y color from the scale value of the B color component in the white preview data; and subtracting the extracted scale value of the M color from the scale value of the G color component in the white preview data.
