Things to consider in choosing a source profile:
• If the RGB or CMYK source space of the image is known, you can assign
the profile that matches that color space or you can convert to the
assigned working space.
• RGB images without the source color space information may require
guesswork to determine the most appropriate source color space. sRGB
has a smaller gamut, but is a universal working space ideal for images
coming from digital cameras and the Internet (or destined for the
Internet). Adobe RGB has a wider color gamut and may work best for
images that contain vivid colors.
• For Unknown CMYK images, we recommend SWOP (v2) or GRACoL for
US markets and Fogra ISO or Euroscale for Europe.
• When working with documents that contain images from a variety of
sources, discuss with your print provider if one working space should be
assigned to all the images or if the original source color spaces should be
assigned individually.
