Hello all, Happy New Year!

I Just purchased an EPSON SCP800 Designer edition which came with Fiery Express. Program is up and running no issues.
My intention for this is to print color accurate proofs to send to the customer for approval and use the printout on-line as a standard for offset printers. Once the hard copy proof is approved, we then would match inks to the print-out and send to the floor.
I read that the software comes with pantone ICC but don't know which one it is in the program. We print from PDF's generated from Ai. What do I need to do in order to get this printer to print to pantone spot colors as well as custom colors? I don't need a server because I only have one designer and 1 printer which I want to use for proofing.
