Drop Shadow Color Issue

[C***@adobeforums.com]

I am working with an ai image to which I have applied a drop shadow. The image is grayscale and therefore I want the drop shadow to be grayscale too.

When I place the image in InDesign and then send that InDesign document to my printer, she says that she is getting a "3 color separation" on the drop shadow that she's been having to strip out.

I'm confused why this is happening because I have the drop shadow options set to Darkness, not Color. However, I notice when I click on Color Guide a bunch of colored swatches appear which makes me think something's wrong.

Can someone please tell me how to make my dropshadow in grayscale, not color??

What is the colour mode of the Illustrator file (File menu)? You want CMYK mode, and you want to use Multiply or Normal for the colour mode and make sure the colour used is CMYK = 0,0,0,100.

It is set to CMYK mode and is Multiply. How would I make sure the colour used in CMYK=0,0,0,100?

Click the image, got to your Appearance Panel, double click the Drop Shadow, click the color, and change it there.
