Dedicated ICC profiles provided to allow accurate rendering of image data recorded in Adobe RGB color space. What is Adobe RGB color space? The most widely used color space for digital camera image data is the sRGB color space. But in addition to sRGB, certain high-end cameras such as the EOS-1Ds/1D/10D are capable of recording image data in Adobe RGB color space, a color space commonly used for commercial printing applications. Adobe RGB color space provides a broader color gamut than sRGB, particularly for colors in the cyan to green region.

The reproduction range of BJ printers is similarly extended beyond the sRGB range in the cyan to green region. In other words, Adobe RGB provides a better match of the color reproduction ranges between these digital cameras and BJ printers than sRGB. Dedicated ICC profiles allow images recorded with extended color gamut in Adobe RGB color space to be printed using the full color reproduction range of BJ printers. Printing Adobe RGB images without the suitable adjustments would result in the substitution of color data outside the sRGB color range with sRGB colors, resulting in incorrect reproduction of colors on BJ printers, particularly for the colors in the gray region in the sample shown above. This is why dedicated ICC profiles are provided. These dedicated ICC profiles allow color reproduction information for image data to be transferred to the BJ printer with virtually no loss, allowing use of the full BJ printer color reproduction range. sRGB PIXUS Adobe RGB The Adobe RGB and BJ printer color space together extend the range of vivid color beyond the sRGB color space, particularly in the regions from cyan to green. The difference is especially noticeable for the greens of foliage and aqua tones of the sea. Adobe RGB image The shaded areas are color regions that cannot be reproduced in sRGB.
