Thank you Ernst and Winfried

I've referred to both of your work/files before I started this 
little project, and they were both very helpful and led to success 
in scanning the 21 step wedge with my Pulse setup.

Now I want to try and go 1 step further and try to scan the Ink 
limiting/curve creation targets in calibration mode with my Pulse 
setup. At the moment I do as you do Ernst and spot scan a random 
number of patch's which visually look close to the Ink Limits, but 
being able to scan all patchs in 1 swoop would be good use of my 
equipment and would enable me to monitor suppliers ink formulations 
for any variance and also keep an eye on the paper suppliers 
coatings, again for any variance in production batchs.

Jamie.
