About PDF:

PDF (Portable Document Format) was developed by Adobe Systems Incorporated with the intention of enabling cross platform, open exchange of electronic documents. It has been adopted by the publishing industry for the exchange of print ready content due to its extended capabilities over PostScript. PDF is preferred by many because it is easy to open and view, it is typically much smaller in file size that its PostScript counterpart, and PDF often eliminates processing errors commonly encountered with PostScript.

Most desktop applications require the creation of a PostScript file before a PDF can be generated. If you choose to submit PDF to The Physician and Sportsmedicine, please make sure that the originating PostScript file is prepared in accordance to The Physician and Sportsmedicine PostScript specifications (located under DDAP Guidelines/Create PDF).

The Physician and Sportsmedicine supports the DDAP (Digital Distribution of Advertising for Publications) recommended guidelines for creating PDF. It is imperative to follow the DDAP recommended guidelines, The Physician and Sportsmedicine's ad material guidelines, and the PDF specifications listed below. From our experience the reliability of PDF is dramatically increased when they are created properly.

Preflighting PDF files, before delivering them to The Physician and Sportsmedicine, is highly recommended. Pitstop, by Enfocus, is an application which will check PDF files against user definable criteria.  Download The Physician and Sportsmedicine's customized Pitstop Professional 5.01 Profile, MH_Pitstop_Profile.ppp, to verify that your PDF file meets The Physician and Sportsmedicine's specifications.  To purchase Pitstop online, visit the Enfocus web site at:
