Expanded Gamut Printing (EGP), also known as Fixed Palette or Extended Color Printing, is a color reproduction methodology that utilizes a fixed set of seven process inks: Cyan, Magenta, Yellow, Black, Orange, Green, and Violet (CMYKOGV). This system significantly extends the printable color gamut within the CIELAB color space far beyond the limitations of standard CMYK.

The primary and strategic purpose of EGP is to accurately reproduce the vast majority of brand-specific spot colors without the need for custom-mixed spot inks. This conversion represents a paradigm shift, turning a costly, time-consuming, and variable spot-color-based workflow into a stable, predictable, and fully managed process-color system. This foundation enables achieving unprecedented color consistency across different print runs, various substrates, and even between geographically separate facilities, fundamentally changing the economics of color reproduction.
