In a multicolor workflow, the standard CMYK ink set is extended with additional colors, thus enhancing the color space. Especially the 7-ink combination CMYK + OGV, i.e. the additional use of orange, green, and violet, can be very beneficial. With these seven inks, you can cover a very wide range of spot colors without changing inks on the press.
Although multicolor workflows are particularly appreciated in commercial and art printing, they offer clear advantages in other areas as well:
- The enhanced color space, also called ECG from Enhanced Color Gamut, enables print products more true-to-original.
- Your pictures will be richer in contrast due to increased luminosity and saturation.
- Separated spot colors are better reproduced, so that you can also display extreme product colors with colorimetric accuracy.
- You save time and money, because no process color needs to be changed and no ink unit needs to be cleaned when spot colors are requested.
There are also multicolor workflows with less or more than 7 inks.
