I'm using Publisher 2000 to create an 8 page Tabloid newsletter.  Having a heck of a time converting the colors to CMYK.  It is a 2 color process printing piece.  I've printed it to Adobe pdf and used PitStop, still RBG.  I've converted to Pagemaker, still RBG.  Most , if not all, printing companies will not accept .pub files for printing.  What is the best way to convert .pub files to CMYK for printing.  This particular job is costing us time and money.  Thank you very much.
