QTR-Quadtone RIP

Hi,

I am new to the forum and need help. I am using an Epson 2100 printer 
with Media Street Generations Quad inks from a niagara supply and 
either Ilford smooth pearl or Monochrome Arles 318g Matt paper (a 
generic Hahnem�hle). Can somebody please tell me a simple way to set up 
the curves etc to achieve good results. I have tried various set ups  
Quad 2100 GQ and Quad 2100-UT7 but the results are poor ( GQ = foggy as 
if there is an almost white film covering the print; UT7 too dark). 
Please help,

J�rgen
