Finding Process (CMYK, non-spot) colors in a file.

So here's the thing...

1.) Scanned image of artwork

2.) Opened in Photoshop and played with levels and posterized it to 6 colors. Looks great.

3.) Convert art to CMYK

4.) Used eyedropper to get the CMYK for each color and made a swatch for each in AI and saved the 6 swatches in a group.

5.) Placed art in AI and used Image trace, set it to limited colors and picked the document library and the color set I made.

6.) Expanded art, and the colors were there, but they broke the link to a spot color and were just CMYK... Ok.

7.) Made 6 boxes off to the side, and used the eyedropper to pick each of the 6 colors so I had a line of boxes with CMYKs color...

8.) Click and box, hit Select > Same Fill Color and then re-assigned the spot colors.. and Hid the selection. I went through each square, selecting Like and reassigning colors.

9.) Seemed to work.

Then I save the thing as a press-ready PDF and when I go into Acrobat and pre-flight the art, it's showing my spot colors AND CMYK plates.

<:\      <--- Confused look here.

10.) Go back in AI, do the Select > Same Fill Color again and hide things, and when I'm done, theres nothing on the artboard.

Note: All the spot colors I assigned are set as Spots, not Process.

So I'm stumped. Anyone know of anyway to tell AI to show me anything thats NOT assigned a spot color? I used the Separations Preview and the CMYK shows nothing. It's all Spot Colors.

Is it AI or Acrobat?
