(note that I *intentionally* dim the lighting when I take the measurements.
Not pitch black, but quite dim. I've been toying with the idea of using a
light to light up the target & colorimeter during placement, and turning it
off during the measurement. I guess the PC monitor could be used as the
illuminant, really)

Ok. (I'm using the Epson ill-behaved RGB driver. :)
I don't know anything about Gutenprint yet - I'd love to have a method of
bypassing the Epson driver without having to fork out lots of money -
if Gutenprint provides a very simple "RIP" I'm interested to learn about
it.......

FWIW, I find it trivially easy to place the puck when the patches are
printed in random order, with very dim lighting. I have set the inter-patch
time to one second.
