We are looking at an equivalent for Pantone P 289 (Midnight Blue) on RAL or CMYK, please advise if this is known to someone.Thanks
Pantone states the CMYK is
100 76 12 70
Merely typing "Pantone 289 in RAL or CMYK" into a Google search presents the Pantone page above as the first result.
I'm unclear why you may feel that's not a valid breakout.
