Question

How do I keep Grayscale images from converting to CMYK

I created my file in Framemaker 7.2 and imported Black and White grayscale images, when I wrote the postscript to create a PDF everything was fine until I did the preflight only to learn that my images have converted to CMYK...These graphics need to print grayscale not CMYK. I am working from the PC and this is a very large document.

    What format were the images in?

    Unless they were EPS or PDF formats, then FM7.2 would have converted
    everything to RGB on output, not CMYK.

    To get true postscript greys from equal RGB values, you must
    configure your PDF printer instance to output postscript grey.

    In the Printer control panel, select the Adobe PDF, then right-click
    and select Properties.

    Then on the Device Settings tab, set the following:

    Convert Gray Text to PostScript Gray: YES
    Convert Gray Graphics to PostScript Gray: YES

    Click OK to set.
