QTR-Quadtone RIP

I'm fairly new to using QT RIP, and I've had a hard time understanding 
many of the settings and parameters, such as the different dither 
algorithm settings when printing, and linearization, and the density 
and limit settings in curve creations, to name a few. 

I've read the material available from the QT web site and also asked 
many questions on this forum (but unfortunately, most of the responses 
I don't quite get). 

So, is there any way to learn more about this process and what all 
these setting mean, such as some good books or reference materials on 
the subject?  

I'm not that dense (I think) and obviously you all are getting it, so I 
think there should be some way to learn about this. 

Best (but still slightly confused), David.
