Yes, colour is not used for the recification. Also, It doesn't warp the 
images - it shouldn't have to (unless your printer and scanner have 
serious problems), it just reads the 2D barcode and works out what part 
of the world it was, and arranges the scan as suitably scaled tiles.

I've found that it doesn't work too well if the scan is a low 
resolution, and it can't cope with PDF scans. Sadly, this means that the 
nice HP 9000 multi-function printer at work doesn't really work for it, 
despite it being A3.
