Toolcrib only works with Xrite measuring devices and they say it is 
really just a diagnostic tool to talk to the device. It will allow 
you to measure in any of the modes directly supported by the hardware 
tool, and output those measurements to a text file with different 
delimiters. It can also export to any "front application" that will 
allow that type of export. With a DTP32R, or DTP22 that I've used it 
with, I normally just bring up notepad as the front app. and set for 
tab delimited data. ColorshopX does the same thing, and also adds 
placing each measurement into it's own scratchpad, and adds support 
for the GMB i1, only it doesn't look at a reference file for scanning 
mode, works great in single read mode. Not sure how well ColorshopX 
works with the Pulse, all the old Xrite scanners make the tool hold 
the patch per scan number, so it knows if there is an error before 
asking the software. Since the Pulse can read without a computer, I 
suspect that it too knows how many patches are in each scan. Toolcrib 
now supports the Pulse, as does ColorshopX, so you might find some 
people asking about using that tool.

Heidelberg Printopen 4 and newer will make a real grayscale profile 
from at least a CMYK target, not sure how it will react if I feed it 
a B/W version of that target, maybe I'll try it later today.

If you want, I can give you a text file from the output of 
ColorshopX. It can export spectral, L*a*b* and XYZ (maybe others like 
denisty), and I know Toolcrib (which I forgot to mention is FREE!) 
can do density and spectral and L*a*b* from tools like the DTP22. Now 
I mostly just use ColorshopX for anything like this, since it gives 
me a bunch of other useful tools that can all share the same 
measurements.
