let me rephrase the Photoshop question

Maybe that'll help jog the memory of someone out there.

Why would an image created in Photoshop and inserted into an InDesign document look one way on the screen and entirely different when it's printed? Why would the zombie background only show up when it's printed? It's not there in the version I'm looking at on my monitor.

And, beyond why, how does one ensure that what's onscreen is always exactly what will print?

Where else can I ask how to fix this when the Adobe sites just keep telling me what I did should work? I've tried contacting the teacher from my Photoshop class last year, but that's a long shot.

ETA: Saving the damned InDesign document as a .pdf and printing that works!!! Thank you so much, lpetrazickis, whoever you are (I don't recognize your user name).

So I'm in business, and all is well, and I can get the job done now. Hallelujah!
