You could obtain a separate plugin…theres one from Aurelon Software called n-color converter that allows Photoshop processing and saves a DCS file… there’s a demo here: thepowerco.com/ncolor_conver … _prd1.html
Or, if you could get the measurement data that created the Monaco Hexachrome profile you could create a new profile with ProfileMaker, then you could then use the GM plug in. Just a thought.
