Of course, this can be disheartening because the colours you see on screens look different from the ones you can actually see when printing your products with a printing machine. This means that it can represent more colours than a printing machine. Remember that the RGB colour model, by means of which – for example – we acquire images through scanners, cameras or via web, has by definition a wider colour space (gamut) than the CMYK colour model. This applies to monitors, with their profiles in the RGB colour model, as well as printing machines, with their Fogra Profiles in the CMYK colour model, which is what we are interested in. Basically, this is needed in order to optimise their intrinsic features. Every device or player representing colours needs a colour profile. In the simplest of terms, it is a set of rules, which defines how a specific colour shall be represented on a specific output device (i.e. An ICC profile is a set of data describing – according to ICC rules and standards – the way colours are represented numerically in a specific colour space. What is a colour profile? And above all, why should we be interested in it? Let us start from the beginning, that is by defining its function.
