QTR-Quadtone RIP

I am making the leap to creating an icc for my 4800 printer.  I have
printed the 51-step random target from Photoshop with "No Color
Management" (ABW in the driver), installed ProfileMaker 5.0.5 with
measure tool, connected my Eye1 Pro and started to scan in "Strip
without gaps" mode.

Every time I try to scan the first line from "Beg" to "End" I get an
error "border patches not correctly detected".  Well to me it looks
like there are no border patches (well, compared to the obvious ones
on a chart like TC9.18).  I have tried scanning the whitespace before
and after the grey patches to no avail.

Any and all help would be much appreciated.

Cheers, --Kip
