I have a b&w photo that I have added a spot of red to. I have done this in PS CS3. When I save the photo (as a psd) and import to Illustrator, and I try to print separations, the entire photo separates as cmyk. I only need the red to separate as cmyk and the rest of the photo to separate as a grayscale.How do I accomplish this?

Rhonda,

without knowing the details:

Choose CMYK profile
Set Gray Dot Gain 20%
Convert image to Grayscale
Select all
Make new empty doc with the same pixel size in CMYK
Paste the selection ONLY into channel K (activate K)

Make selection for color area in the CMYK doc
Define color not by Spot but by CMYK
Modify the selected area by the color
(for instance Fill or Hue-Saturation, mode Colorize)

It’s now a CMYK image with K-only gray parts and
colored parts.
