Missing pantone color Indesign CC 2021

Also note that prior to 2010, the Pantone lists in Adobe software were simply called "Pantone".  After that (CS6 and up), they are called "Pantone+" [Plus]. The Pantone+ colors stayed that way until about 2019 (although new colors were periodically added from 2010-2019 to the Plus libraries). Sometime in 2019, they dropped the + [Plus] moniker and emphasized the "Formula Guide" name. However, Adobe software is still installing the Plus libraries. Now, with their extension, it looks like Pantone is trying to get into the subscription business too, although they do have a free version of their account.

My opinions for using Pantone color guides...

Solid Colors: Use the Formula Guide IF you are actually printing spot/solid colors. If printing as a true spot color, you can make your own spot color in Adobe software, naming by the PMS #, and make the color look as visually close as possible to the color. This will print out on a separate separation and the printer will print with the PMS # ink mix. (Tell them what version of the guide you are using.) For example, fluorscent and metalic inks can't be reproduced on screen, so if doing a 5/C job, I don't really need to use the libraries to create the color. 

Color Bridge (previously Solid to Process guide): I use this ONLY when a client gives me a solid color # and I'm printing in process (CMYK). I do NOT use it to pick colors for a CMYK-only job. I call it my "CYA guide"--I can look up how close the color will print in CMYK and warn the client in advance, rather than the client getting mad after the job is printed. (I refer to it as "being disappointed up front rather than after-the-fact". 

Process Guides: I used these when I am picking the colors for a process-only job. Also, if a client does not have a predetermined color in mind (that is, a Pantone spot color), I show them this guide. I still have to warn them about differences in paper and press quality, but generally, the guides are pretty close the the final job. The nice thing about the CMYK guides is that they don't go out of style like the spot colors do. If you take good care of the guide, it can last a LONG time. I still use the old Pantone guides. (BTW, I have the old pre-Plus Pantone libraries if anyone needs them.)

Laser Print Exception: If the final output is a laster printer, I'll test the true spot color against the Color Bridge conversion. Since lasers use toner and "bake" the toner to the top of the paper, they can sometimes do a better job printing the actual spot color. But you need to test it first.
