Marvaco has awarded Siegwerk Group an expanded gamut printing (EGP) partnership certificate in recognition of introducing new ways to use offset and flexo inks on packaging cartons, fiber and plastic materials, among others.
EGP is a colour separation method where prints are implemented with digitally assisted ink blending in a more predictable, precise and cleaner manner. The CMYK colour gamut is enriched with OGV (orange, green, violet) process inks, which more than doubles the number of available colour shades compared to the Pantone+ colour series, without needing to change the colours and using only seven standard colours.
Siegwerk has developed a new EGP printing ink series for offset printing and flexography. With the new inks, packages can be made more colorful while the printing process becomes more flexible.
