I use to print and build profiles for printers so I know enough to be dangerous. I use to get magenta shifts when I accidentally double profiled which means I didn’t set the dialog boxes correctly. I can’t look at aperture right now cause its doing a major Vault change (24+ hours). And I don’t use that camera. All I can offer is to double check your settings in apertures dialog box and any subsequent dialog box that comes up. I feel your pain….Always felt that all printing in all photo editing software is difficult and not user friendly.
