TORONTO— Ryerson University has just published a detailed study of expanded gamut printing, based on a series of extensive tests using commercial colour management systems to process and print test forms containing PANTONE spot colours. The author of the study, Dr. Abhay Sharma. Expanded colour gamu  printing is a new approach in colourreproduction that expands the colour gamut of conventional CMYK printing processes via the use of additional colorants, such as Orange, Green, and Violet (OGV) inks. While expanded gamut printing can be used for images and commercial printing, the biggest and most immediate ROI is in spot colours for labels and package printing.The Ryerson University Expanded Gamut Study used a “shoot out” format that evaluated solutions for expanded gamut colour printing from Alwan, CGS ORIS, ColorLogic, EFI, GMG Colour, Heidelberg, HP, Kodak, Hybrid Software, and X-Rite.
