its the afore mentioned curmudgeon factor... I once went down on behalf of a major art book publisher (ie. big client for the printer) to a major glossy book and magazine printing company, and it was the same... print machines not profiled, scattershot colour management, and hope for the best (the reason I had to make my way down to the middle of nowhere location to jaga the colour in the first place)...well since you do work with them regularly isn't it possible to demand higher standards after awhile.heh.
you are the client afterall
