QTR-Quadtone RIP

Is there a good manual for using quadtone rip?

Specifically the 

gray highlight
gray shadow
gamma 

functions... 

This is my firs post, I am trying to figure out the best profile for making negatives for PTPD (platinum palladium) printing.

I am having good results, however my higher mid tones are printing too hot...

Thank You In Advance for any help.

Corey

There is a method of controlling Highlight, Shadow and Gamma using an ACV curve.  Here is an article geared specifically to making digital negatives:

The above article is geared more toward Silver paper.  Here is one geared toward Pt/Pl:

Thank You Robert.

I am actually familiar with that text, and the language is difficult for my brain to work out.

Moreso I am looking for information, in addition to the gray gamma, grey highlight... for instance what is 'grey toner' 

Is there a definition to all this somewhere?

Thanks.
