Checks objects to see whether or not they are ICC tagged or tagged with a particular ICC profile in a particular color space. You can check if the fill and/or stroke of the objects are ICC tagged.
Every input and output device reproduces color and grayscales in a slightly different way. As a result, the colors you see in a PDF file on your screen may not match the colors produced when you print the PDF to an output device.
ICC color profiles are used to avoid this. An ICC color profile is a mathematical description of the color space used by a specific device. In other words, the color profile describes how the colors produced by the device relate to the reference CIE LAB color space (a device-independent color space). As such, they allow you to set up a workflow in which all devices use color management to compensate for their individual color reproduction characteristics, based on the information in the ICC profiles.
