If you prepare alot of visualizations & graphics for inclusion in posters or magazines, then you’ve undoubtedly had to deal with printing issues. Adobe has a great PDF available on their website on how to use some of the more advanced print preparation features of their CS4 tools on their website.
Among other topics, this guide introduces you to forensic tools, such as the Overprint Preview option in Adobe Illustrator®, Adobe InDesign®, and Adobe Acrobat® 9 Professional, as well as the Output Preview function in Acrobat, all of which are invaluable in highlighting potential problems. The earlier you can pinpoint problems in a job, the less expensive and complicated they are to rectify.
The document is a ~140page PDF available in both a Low Res(4.6M) and Hi-Res (17.7M) version. They also have one for CS3.
