Image>mode>grayscale.
Acrobat will always show four plates. There should be nothing on them with a grayscale image.

what file are you viewing in acrobat?
a grayscale Photoshop PDF or a PDF made from a layout? What are your distiller options, or PDF export options regarding color? Should be "leave color unchanged".
I am working with a grayscale image (mode>grayscale). Even in photoshop, I can see values in the CMY colors in the color picker. I placed the grayscale image in InDesign, exported to PDF, opened the PDF in Acrobat, opened the print dialog, advanced button, output, separations, and when the plates are checked/unchecked, you can still see color in each of the 4 plates.
Yet, also, with the same PDF file in Acrobat, I look at advanced>separation preview, there’s only color in the black plate and not the others.
Why is it different when I’m looking at the exact same file?
In the info palette click on the eyedropper and select actual color. As for InDesign to PDF, how are you doing it? If you convert to RGB, Acrobat will convert to CMYK for separations and you’ll get four colors.

Bob —
I set the grayscale image to actual color in the info palette. I placed it into InDesign and exported. Looking at you advice, I checked and it was CMYK, so I changed it to Leave Unchanged. I still get the same results with color on all 4 plates. I’m including my PDF Export summary – maybe there’s a clue in there….

Does the info palette in Photoshop show it as only K? What does the separation preview palette show in InDesign?
Bob
I’m using InDesign 2.0 – is the separation preview palette new to CS?
