I need to create a poster for a conference. Which is the best image format that I should save my image file as for highest quality printing? I am using Mathematica on Ubuntu 10.10 to generate these images.

Short version: Export to a format that supports CMYK colorspace and maintains image fidelity. In order of preference:
Explanation: There are two factors to consider for high quality printing:
Ideally, you should export as a vector format in CMYK colorspace. Mathematica supports EPS export:
In addition to infinite resolution, the file size should stay relatively small.
However, one disadvantage of vector file formats is text in non-standard fonts is often rendered incorrectly. In this case, it may be simpler to export a raster (bitmap) image. I suggest the TIFF format:
Make sure to use at least 300 DPI. Depending on the physical size of your poster, this could require a HUGE file.
I do not recommend:

Since you generate your graphic which Mathematica I assume we are speaking of vectorial graphics. In this case keep it in a vectorial format and it will properly rendered at the right size and resolution when inserted in the poster. Both PDF and EPS will do the job.
PDF tends to be format of choice for high quality document reproduction. We tend to think of it as best for creating docs that lots of people can view. But Adobe has built it up into quite the de facto standard for the full range of printing needs from the web form all the way to the full color press operation file. – music2myear – 2011-10-24T21:43:22.270
1Does this poster contain vector graphics only? Or are there any bitmap graphics as well? – slhck – 2011-10-24T18:33:34.910
By the way: I've seen you've got a couple of answers on your questions already – but you haven't accepted any of them, nor have you cast more than one vote. It would be really great for the site if upvote all answers that you find helpful and accept the best one! – slhck – 2011-10-24T20:39:17.680
