Sorry for the confusion. I have 2 logos; both designed in Illustrator - one being PMS 3015, the other white. Both have been placed into an Indesign document. There is black type in the document. I want the document to print P+K/0, no CMYK so it is cheaper.
When i did a preflight, it was telling me the white logo was CMYK, hence the confusion. Form what I am gathering, the service provider will know to print the white logo as paper, so it will be produced as 2/0, not 4p+P/0.
