What was a CVS color?

Heh! If anyone would know it, you would, Colin!

Indeed, it lists them all on p 97 of that Enfocus manual.

CVS is an old way of saying Process Coated; now simply C.

I wonder how many times over the years Pantone has changed these denotations?

Thanks everyone. 

Cheers for the link from Pantone's site by @Jeffrey_Smith 

An even more detailed list of suffixes can be found on pages 96-97 of the Enfocus Action List manual - https://www.enfocus.com/en/support/downloads/pitstop-action-lists

FYI - Pantone and Esko (Enfocus' parent company) are both owned by Veralto.

Here's the link to Pantone's Suffix

It was in an early edition of InDesign Classroom-in-a-Book in a lesson file. This would be circa 2000.

I know, generally, that Pantone has adjusted the way they describe and denote colors, but I did not remember this one.

I have a brief instructive article about all the Pantone nomenclature on my website, but this one is not in my researched list.

Doesn't ring a bell. The only connection I can find is for branding info/colors for the CVS pharmacy chain.

Typo? Some designer's secret code?
