No, it’s not. RAL colors are defined only for surface colors, like lacquer (varnish? paint).

Printing colors work differently, they’re mostly transparent.
A parallel to RAL in printing colors would be Pantone (or HKS in Germany, Toyo in Japan).
But these are copyrighted, so we would be most probably not allowed to ship a library of these.
(If I need some spot color, I look up the CMYK/RGB mix in Photoshop or InDesign.)

That would make no sense IMO.
