Thank you!

Never heard of it. Do you have a link?

This is all extremely tricky, because one has to ask at which level this can be implemented. Is it the provider of digital colour swatches? The design program? The print operator?

IMHO, it's up to the operator and versatile printing software to handle this issue. Designers' options are fairly limited in this regard.
