If the project requires full color (for example, it contains scans of color photographs), you must use process color. Process color is a method of producing virtually any color using only four ink colors: cyan, magenta, yellow, and black (CMYK). The final colors are produced by mixing percentages of these four inks. Process color requires only four color separations.
An example of process color separations
Corel now supports Pantone Hexachrome, a new type of printing process that increases the range of printable colors. Pantone Hexachrome uses six different ink colors (cyan, magenta, yellow, black, orange, and green) to produce full color. To use Pantone Hexachrome color effectively, use the Pantone Hexachrome color palette. Pantone Hexachrome color is sometimes called high-fidelity color. Talk to the service bureau about whether you should use Pantone Hexachrome color.
