Abstract

This study seeks to confirm or refute the statement that Pantone Extended Gamut (XG) can reproduce 90% of all Pantone Solid colors (PMS) by using seven process colors (CMYK+OGV). At the same time, it is investigated which colors within the 10% that cannot be reproduced in this system.
By using a comparison of Pantone's own "reference values" (CIELAB values) it appears that only 57.6% of all PMS colors can be reproduced if the tolerance is ≤ 2 DE2000 and only 82.7% of all PMS colors can be reproduced if the tolerance is ≤ 3 DE2000. The tolerance will have to be ≤ 3.7 DE2000 in order to reproduce 90% of all PMS colors.
In an attempt to plot the two gamuts in a CIE a* b* projection diagram, it proves surprisingly difficult to identify the seven primary colors of XG. PMS Orange 021 is apparently not equal to XG Orange. PMS Green is apparently not equal to XG Green, and PMS Violet is apparently not equal to XG Violet.
Likewise, it has not been possible to identify the secondary colors (overprints) of the XG Primary Colors. A suggestion for gamut plotting is proposed.
