duotone and InDesign separation issues?

[JCowan]

I've created a doutone in Photoshop, saved as a eps and placed it in InDesign (all CS5). The file will separate correctly in Photoshop but the second color will not separate correctly in InDesign. Can't find anything addressing this issue. Can anyone help?

Thank you!

In inDesign for commercial printing, save the image as a native psd file or as a Photoshop eps so that they separate correctly into the duotone colors.

Are you doing as follows How to Convert an Image to a Duotone in Photoshop

I have tried that and it still will not separate correctly. The second color prints as a blank piece of paper. It will separate in Quark but we are no longer using that program. Thank you!
