Please repeat after me ... Adobe Illustrator is NOT, repeat NOT, repeat yet again NOT a general purpose PDF editor.
Adobe Illustrator only "understands" a subset of PDF, the subset that corresponds to the objects, modes, and options of Illustrator. The only PDF file that is "safe" to open in Adobe Illustrator is a PDF file saved in that version (or earlier) version of Illustrator using the "save editabilty" option. Opening any other PDF file subjects that file to loss of and changes to content. Don't do it! It is not recommended or supported by Adobe in any way, shape, or form. Use Acrobat 7 Pro or Acrobat 8 Pro to do such color conversions. - Dov > -----Original Message----- > From: Madeleine Reardon Dimond > Sent: Thursday, November 30, 2006 9:14 PM > To: framers at lists.frameusers.com > Subject: RE: Greyscale > > Dov wrote: > <<Yes, I am definitely referring to EPS or PDF files > imported into FrameMaker. > > There is no "convert to grayscale" option in > Distiller.>> > > I've been faced with the problem of converting color > to greyscale in a document full of pdf imports.
