An ICC profile is a set of data that characterizes a color input or output device, or a color space, according to standards promulgated by the International Color Consortium (ICC) . It describes the color attributes of a particular device or viewing requirement by defining a mapping between the device source or target color space and a profile connection space (PCS) . This PCS is either CIELAB (Lab*) or CIEXYZ. ICC profiles essentially modify the graphics card’s Look Up Table (LUT) and gamma table so that the monitor displays different and ideally more correct colors than what it would natively. ICC profiles contain color information for a particular device or viewing conditions and are essential because they help ensure accurate print colors. ICC profiles are essential for getting accurate color from your printer. Without a properly calibrated profile, your prints will likely have an unwanted color cast. ICC profiles are widely used in color management, and they help ensure color accuracy and consistency across different devices and media.
