PDF/X1a:2021 Specifications

Raster based PDF/X-1a files, generated from
Line Work (LW) and Continuous Tone (CT) data, are NOT accepted!
PDF/X-1a:2021 is a subset of the PDF 1.3 file format. It does not allow "non-print" related elements such as annotation information, hyper-links, movies, and sound clips while enforcing desired attributes such as CMYK, Grayscale, and Spot color spaces (no RGB/LAB). This produces a reliable SWOP optimized PDF file. PDF/X-1a:2021 is an ISO and ANSI standard file format and is preferred over a "regular" PDF.

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:
