The EXTENDED GAMUT Advantage for Printers
For spot color simulations, properly separated files will use one to three of the ink colors. There are several prepress solutions that support 7-color extended gamut separations, and in packaging, Esko Equinox is one popular example. Equinox can also perform spot-to-process conversions if a file was designed using spot colors.
Seven-color process is actually more stable because 4-color process builds from colors that are very far apart on the color wheel. Even a slight shift in density or strength of any ink color can shift the resulting build color quite a lot. When using seven inks, colors are built from up to three inks that are closer together on the color wheel. If one ink shifts in strength or density, the impact won’t be as great. Since the stability and consistency of 7-color process is so high, you can set better expectations for achievable color before you even start printing.
What are people saying?
The early numbers are very encouraging; 25–50% of printers using ECG reported saving time during makeready because they’re only changing plates, not inks. They also have more opportunity to combine runs and take on more short run jobs.
More productivity, reduced waste, and less downtime means increased profitability, and consistent color results means happier customers who are more likely to come back for more.
