QTR-Quadtone RIP

I've seen in Version 2.5.1 tech notes of this rip, that it now has profiles for papers that had to 
be printed  with photo black (K2) ink with the Epson driver.

As far as I know papers such as Ilford Galerie Smooth Pearl an all Epson Premium photo 
papers need the photoblack ink.

So, if I use any of these papers, I understand I need to switch to Photo black from matte 
black.

Am I correct?

Thanks
