Rotor edge rubbing

I just moved a set of Deore M575 disc brakes from a Stumpjumper to a Rockhopper and I am getting rubbing front and rear (rear most). I have realigned both sets several times following the normal technique of loosening the calliper nuts, squeezing the the lever and retightening whilst holding the lever down. But I still get rubbing. Then on close inspection of the rotors I noticed they were shiny on the outermost edges, suggesting they were rubbing on something, the calliper housing presumably. I confirmed this by using a marker pen to ink over the shiny patches and spun the wheel, sure enough the ink was immediately scuffed off.
Has anyone seen this before? Could I have refitted the callipers wrongly or do I need a different mounting bracket for the Stumpy frame? I could put washers between the frame and the bracket but this doesn't seem like a good idea as there wont then be a continuous flat contact along the length of the bracket and for some reason that seems important.
Advice please?

you may get away with just putting a small .5mm washer under each side of caliper to lift it

No I haven't but both the brakes and rotors were transferred from another bike where the worked perfectly together and did not rub.

they worked fine on one set up and now you have messed it all up and need to do it all again.
every time they are messed with they need bedding in.

no need for shims unless old IS mount and these are not.
what happens to the disc when you pull the lever?
