Dear Scribus Team,

There is no need to name a Spot Color as Pantone 145 CV  ( just an 
example)  you can name the color "Spot Color 145 Coated" and leave the 
Pre-Press workflow system substitute it by whatsoever is desired.

A lot of big companies have done it without any royaltie or penalty.

Regards to ALL and have a Happy New Year !
