Colour Accuracy of Corporate Colours in Expanded Gamut Print Reproduction

[abstract para. 1] "Expanded gamut printing, as the name implies, expands the gamut of printable colours that can be achieved through a combination of CMYK by adding Orange, Green and Violet (OGV). Through the addition of these additional three colours it is possible to cover almost 95% of the colours that are in the Pantone® colour guide for printing. The benefit of using expanded gamut printing is, that the same inks can stay in the ink fountains of a printing press and only the printing plates need to be changed from job to job. No time consuming ink changes are necessary if a printing press uses the expanded gamut ink set."
