A Study to evaluate current color matching procedures

The primary objective of this study was to determine if current color matching procedures produce the desired color on the final printed package. A problem with printed items is that multiple departments and companies are involved with the choosing, specifying and approving of colors. This study evaluated one part of this procedure - the printed color standard. The printed color standard is used by the printer and packaging buyer to assure color consistency. However, there is often little understanding of light sources, color perception, chromatic adaptation, metamerism and ink dry-back. Color reference systems, like Pantone, recommend updating their color standards every six months to assure color consistency. Yet, printed color standards that are produced with less inert inks and a more reactive surface, are often used for years. This study evaluated the drying and ageing characteristics of ink both visually and spectrophotometrically, and showed that the current color matching procedures need to be improved to reduce the chance of off colors
