To start the Pack and Go Wizard, point to Pack and Go on the File menu, and then click Take to a Commercial Printing Service.
The Pack and Go Wizard will take you step by step through the complete process.
Using the Pack and Go Wizard is fairly straightforward. The first thing you have to note is that there are two wizards: one packs a publication so that it can be conveniently transported to another computer, the other packs a publication so that it can be conveniently taken to a commercial printer. The differences are minor, but significant. Be sure that you select the wizard that packs the publication to take it to a commercial printing service, otherwise the packed publication you hand off to your printer may be unsuited for commercial printing.
Before you start make sure that you don't have missing fonts or missing linked graphics.
