Mine is as yours except my Colour Space is As Document, and ICC Profile is Use Document Profile
In My Document Setup, Color Format is CMYK/8 and Colour Profile is Coated GRACol 2006 (ISO 12647-2.2004)
Thanks for the feedback. I've also tried that (my document is setup exactly the same as yours in terms of colour format / profile) but I still get the same result. I might just try and get the test print delivered and hope for the best!
