My PANTONE guide has an ink company custom cover? How is it different?
Pantone allows PANTONE Licensed Printing Ink Manufacturers to put customized covers on PANTONE formula guides which they purchase for resale or distribution to their customers. This is done to allow the ink companies to advertise their products in conjunction with the PANTONE Colors. The sheetwork containing the colors in these Guides is produced by Pantone and is the same sheetwork that goes into the guides that use the standard PANTONE Covers.
