QTR-Quadtone RIP

Thank you all for your good advice.  I went back and reprinted the ink separation test using the GUI, the Adobe color management utility, and making the color space (Adobe 1998) the same as the printing space and got good results with all.  This time, however, I printed using the Matte Black ink on the 3880 (see Reeder, "Digital Negatives", 2010, p. 36).   I did drag out an Xrite 361 from the back of the closet and read the negatives (not sure if reading digital is appropriate here, but what the ....).  On the UV channel, the Matte Black read 4.33 on the 100% square, the PhotoBlack read 2.91.  the 70% square read 3.20 v. 2.46.  

Again, thanks for all your advise.....lyle
