In Publisher, importing a CMYK jpg or png and using the K only button to convert to a spot colour monotone and I have these results (see attachment). The master displays correctly, but the document page has some kind of super intense duotone effect. I could only change this by editing detached on the document page and re-clicking on K only. Kind of defeats the purpose of having the master! Also had some odd effects importing B&W images made in Photo which end up looking washed out in Publisher. What's the story here?
