[pdftex] problems with embedded pdf-pictures

To be sure my pictures have the correct colours and colour type I'm
using the EyeDropper plug-in from EnFocus (PitStop).

The duotone PhotoShop pictures (black and magenta) were saved as PDF
files and then included into the document using graphicx.

When I'm controlling the colours I got all colour information except
for the pictures!

I contacted the support from EnFocus to help me and they've sent me
the following two email which might be useful:

> The images are inside a form.  There are different
> types of forms.  If the image contained OPI
> information, it would also be located in a form, but
> this would be solvable with PitStop. Delete OPI would

> In this case the form coming from Unix, so PitStop

So now I'm wondering how to solve this problem?
