              Closing. I've updated the Device N to better detect CMYK channels. Will need to do a round of QA for this one.

              I have is a pretty hard look on Friday but couldn't find an issue with how we're handling the alternative colour space. I suspect we'll have to look at supporting the names [/Cyan/Magenta] in order to get this PDF to render correctly. Will have to differ until after 4.2.

              Looks like its actually a Device N colour space. Should be able to do something about it.

              Some tracing notes.
