The EXTENDED GAMUT Advantage for Printers
Demands in the industry have made it even more difficult to print packaging using CMYK alone. Although it’s the most economical printing process, it provides a very limited gamut of color, and even in the best conditions can only hit about half of the PantonePLUS colors. There’s just no comparison in color vibrancy between CMYK and spot color inks.
To hit special colors, many printers choose to add spot color inks to their CMYK process. Spots provide the best quality, but they’re also expensive, increase makeready time, contribute to large ink inventories, and are cumbersome for short runs. And what happens to the extra ink you don’t use?
Above: Extended Gamut printing provides a larger palette of colors for reproduction than you can get from CMYK alone. In this graphic, the smaller area shows the range of colors in CMYK printing, while the larger area shows the range of colors that can be produced with CMYKOGV.
With Extended Color Gamut (ECG) printing, you can achieve a good visual match for approximately 90% of spot colors without color mixing. When used with photographic images, it can greatly enhance the saturated colors, especially those in the areas of Violet, Green, and Orange.
Another advantage of ECG is the ability to gang up jobs on the same plate set that would normally require different spot color inks. This helps meet today’s requirements of shorter print runs for smaller just-in-time inventories.
Printers can also achieve less downtime and better press utilization. Once you load the seven ink colors, you only need to change the plates between jobs. The same inks stay in the press job after job, meaning fewer washups and shorter makeready between jobs.
The CMYK inks conform to the ISO ink and print standards that are already in use for offset, flexo, and gravure printing, and the Orange, Green, and Violet inks are the existing Pantone base inks that your ink vendor is already using.
