Digital BW, The Print

Hello Everyone

I just started experimenting with QTR(for Windows)on an Epson 7600 
printer(with Ultrachrome inks - with Matte black) and EEM (Epson 
Enhanced Matte)and HPR (Hanamuhle Photo Rag)papers.

Some of the posters on this thread have made reference to QTR having 
capabilities for:

- Softproofing

- Profile Tweaking

Could you please explain how you go about using these two features ?

Thanks
