Adove: All Adobe’s graphics applications support direct conversion to PDF. Other software usually requires the file to go though Acrobat Distiller, although you may still be able to initiate this process with one click. PDFs can be output directly from QuarkXPress, and Mac users can output PDFs from any application thanks to a feature built into Mac OS X, although the level of control is not really sufficient for prepress work. The distilling process is almost instant for simple files, but can take minutes for large documents.
