Did anyone ever find out if Merritt Graphics has that chart in vector?? My god, that could possibly be the best color chart I've ever seen...
If you use Corel macromonster.com has Noisia Applications Color Spectrum Pro that will help you create a set of color swatches containing all of the nearby CMYK variations. I have it and it works just like the $200 program Nazdar tried to sell us.
Among a few others offered,... this is also a very good color reference --- thanks for sharing. JPHere is a vector chart I made a long time ago. It matches the pantone book and can be cut out and put in a binder.
Here you go.
