Abstract

Expanded Color Gamut (ECG) in printing is a technique that extends the range of colors beyond the traditional CMYK (Cyan, Magenta, Yellow, Black) process by adding additional inks, such as Orange, Green, and Violet (OGV). ECG is a step towards a more sustainable future for the printing industry. By allowing printers to omit spot color inks, ECG eliminates the need for a large ink inventory of pre-mixed spot colors and since it is fixed color palette printing, standard primary colors can be kept in the printing units, leading to less frequent print unit wash-ups and allows even the co-printing of jobs, resulting in less use of resources e.g. organic solvents, and lower substrate consumption.



The primary objective of the comprehensive study on which this session reports is to gain a deep understanding of the current state of ECG adoption. This thorough diagnosis will guide the development of strategic recommendations for advancing ECG integration.
