Trap Presets

It’s unlikely that you’ll be required to use the Trap Presets features in Acrobat 7, since trapping is a complicated undertaking that’s best left to the knowledgeable folks at the print service provider. The Trap Presets feature in Acrobat doesn’t actually create traps within the PDF file: It lets you specify trap settings that are subsequently used as instructions by a RIP that uses the Adobe In-RIP Trapping engine. The trap settings you choose only affect the print stream out of Acrobat—no trapping instructions are stored in the PDF. However, the presets you create are available as presets in Acrobat for future use.
