Puzzling image behavior

[Audelin]

I have created a postcard for a client in InDesign and on it is a star that is supposed to be yellow. Originally, this was also an ad in a local newspaper, and when it came out printed in the paper, the star was green. This was then an object created in InDesign.

So I went to Illustrator, created the same object as a vector one with a CMYK profile of C0 M10 Y85 K0, and linked the star to my InDesign file. The next newspaper ad came out fine.

Next was the postcard, which was printed digitally. I created the file in InDesign, using the star from Illustrator and it came out green again! (Unfortunately, my client did not forward me the proof for the printer and approved it, sigh).

My question is: why does this image come out green in print?

Are you sure that you didn't have the star set to overprint?

^exactly what Ampersand said. Also, check your Effects palette to ensure you (or someone else) haven't inadvertently set an effect. Remember with placed objects to check both with the Selection tool (solid arrow) and the Direct Selection tool (open arrow).
