From the instructions you will have a little grub screw in the holes indicated if you can adjust the centering. Going from my record calliper that should be the one in the 2nd photo you posted, there wont be a screw on the other side. I found when setting them up it helped to have the cable set up so that the pads were really close to the rim, with the bolt holding the caliper onto the frame slightly loose. Apply the brake and then do that bolt up. Should get them pretty well centred.
