Digital BW, The Print

Hello I am new to the group.
 I am using UT7 inks with the epson print driver on a 2200 printer
I have acces to a Monaco spectrophotometer and would like to be able to linearize my 
printer so I can write profiles for differnt paper types and take advantage of photshop
cs softproofing feature. I have tried the procedure using the 21 step wedge and 
making custom dot gain cuves however this limits you to working in 16 bit grayscale
if you are working with a monotone rgb file it wont softproof. could anyone recomend 
a way around this ideally I'd like to be able to write profiles or at least linearize using 
the monaco software and the dtp41 spectrophotometer. however the linearization 
chart that is packaged with the monaco software does not have a complete strip form 
white to black it is composed of 2 colums and the second has some yellow wedges in 
it. anyone recommend any tutorials etc on this subject.
thanks Josh T.
