Try changing your transparency blend settings to CMYK.
Also, put the text on a layer above the image.
See if that helps.
It probably won't.
Grayscale is treated in ID as being on the Black plate of the current CMYK working space. That's probably not the same as the grayscle profile you used in Photoshop, s othe image may print darker or lighter than you expect. In normal view you see the Photoshop preview, if you add transparenency, or swithch to Overprint Preview you'll see the more accurate output preview of how the file will print.

In normal view the grayscale is previewed as 2.2 gamma (or sGray), so it would match the PS preview only if the Gray profile happened to be 2.2 Gamma. Try assigning something like Dot Gain 10% in PS and you'll see that the normal view doesn't have a relationship to the PS grayscale display
OK, thanks. I get really confused by what's going on with grayscale previews, and you always do such a good job of explaining it. I think it's my advancing age....

No, it's confusing. I never understood the 2.2 gamma preview until I realized it was a hedge for documents headed for a screen.
