That's not possible.

First, Pantone comes in two versions - coated and uncoated - which are 
very different.

Second, Pantone does not use the usual pigments. They additionally have 
some pure pigments of blue, red, green and yellow (and their 
combinations), which are out of RGB/CMYK gamut (~colour space).

Pantone is aimed to order a ink by number, and the ink manufacturer (or 
your dealer) mixes this ink from the Pantone base inks. Then you get a 
can of ink identically to Pantone xy, which you use with an _additional_ 
printing plate.

If your target is the usual 4-colour/CMYK process, then you should 
define your colours in CMYK-values (or raster percentages). Never use 
Pantone in this case.
