QTR-Quadtone RIP

Hello, Group

I own ImagePrint, but have been testing qtr on ep enh matte for a few 
months, and have found it to be superior in rendering shadow detail.  I 
also like the greater latitude it provides for toning.  One question:  
I just d/l the latest version, and was pleased to find the profiles for 
semi gloss paper. So I ran a print on ep premium luster with the 
permajet oyster curves, and was pleased to get a fairly nice print with 
no metamerism or crossover, and only minimal bronzing in some of the 
grey.  I wonder if anyone is getting great prints on luster or gloss 
paper, without any bronzing or posterizing, and if so, what 
paper/curves/paper settings you are using?

Thanks

Jack
