Bounding boxes appear in Acrobat after exporting from InDesign

Question

Whenever I create outline fonts in my CS3 version of InDesign (I haven't upgraded to CS4 on this one program yet), I'm left with some very strange thin white lines surrounding some or all of the resulting letters that look suspiciously like bounding boxes. This never seems to occur if I don't create outline fonts, but simply embed the fonts and create a PDF using the Export command, so I have to believe the anomaly has something to do with this conversion process within the program. If I use illustrator CS4 to create outline fonts and then place them within my InDesign documents, I don't appear to have the problem. However, that's not a very desirable solution as it negatively impacts the fluidity of layouts and the ease of design, both of which I use in design for.
And yes, these small thin white lines do print, so the problem is far more than merely academic.
Has anyone else ever experienced this issue, and if so, how did you solve the problem (assuming you did)?

Answer 1

Sorry about that, I apparently forgot to attach the file; have done so now.
The method I'm using for creating outlines is simply to use the "Create Outlines" command under the Type menu within InDesign. Then I create my PDF files by using the Export command under the File menu and choosing the PDF/X1a option. 99% of the time I get perfect results, it's only when I try to make outline type that I encounter this problem. You'll clearly see the artifacts in question in the example attached.
I don't know whether or not the press would have printed these artifacts, as you suggest, since no printer has been willing to execute a file that shows any anomaly in the proof process. I can't say that I blame them.
Hopefully you will see what I'm talking about and can recommend a solution, though I like your idea of simply giving them a properly executed file and then telling them to get a life. It hasn't worked so far, as I unfortunately deal with a lot of Neanderthals around here, but I suppose it's worth putting forth again the next time this issue arises. It will.
By the way, no print house of my choosing is this far behind the curve, if at all. These cavemen are always printers who have long-standing relationships with my clients, and for whatever reason (generally lowest cost I'm sure), the clients think they hung the moon. We, of course, no otherwise, but it does it profit a designer to tell his client he or she is crazy for using a printer who is a decade behind the technology curve.
We cowboy up and seek solutions, eh?
