With what Engine/CMM?

This can be a property of having a CMM that does not play well with a certain profile. I'd recommend using Adobe ACE engine. Depending on your colorsync setup and version number, of Photoshop, if you've chosen Automatic under CMM it will lead to using the Apple CMM under the print dialogue, or Adobe ACE. Scum dots (the popular name for what you are seeing) can also be a property of the LUT in the profile having an even number of grid points which, in combination with the CMM, can lead to interpolation (and thereby slightly less accurate results) of the white point. Due to licensing restrictions not all profiling applications can be used for building generic profiles. It's years since I built that particular profile, I can't remember the specifics, but I can tell you it wasn't built with what I currently use for profiling...
