How To Leverage Gamut Metrics For ECG Printing?

Expanded Color Gamut (ECG) printing process increases the color gamut of a traditional CMYK printing process by the use of additional inks of intermediate hues, for example, orange, green and violet. The increase in the attainable color gamut, however, is not often evaluated fully. The increased color gamut may present challenges in a color reproduction workflow, such as an accurate simulation of the expanded color gamut process using an inkjet proofing device.

Gamut metrics can help in analyzing color gamuts of ECG printing processes. This study explores a number of use-cases for comparing and analyzing color gamuts in context of ECG printing process.

The results show that the gamut metrics can provide valuable insights into ECG printing process evaluation. Use of the gamut metrics should help users to select the ECG device or printing conditions or inkjet proofer that best matches the reproduction aims. It should also help users evaluate the gamut of their ECG devices against the appropriate reference color gamuts.
