TIFF/IT-P1 Specifications

Note: TIFF/IT-P1 is not equivalent to a Photoshop® Tiff!

TIFF/IT-P1 is the preferred file format for the submission of digital ad materials to The Physician and Sportsmedicine. It is recommended by SWOP and is ANSI and ISO accredited. TIFF/IT-P1 has proven to be an extremely reliable and widely accepted file format. It is a raster based file which means that it has already been RIP'd (Raster Image Processed). In other words, all of the vector data (i.e. fonts, logos, gradient fills, etc.), commonly associated with PostScript™ and PDF™, have been resolved to bit map data. This results in a very stable, predictable file.

Systems capable of generating TIFF/IT-P1 were typically limited to high end, proprietary CEPS systems (i.e. Scitex), however, there are now lower cost solutions available which run on Macintosh and PC platforms. For a list of vendors with TIFF/IT-P1 capable systems, please click here.

If you prefer to out source the creation of TIFF/IT-P1 files, please refer to the DDAP DAD (Digital Ad Database) list of providers at

TIFF/IT-P1 File Requirements:

Line Work File = .lw

• Spot colors should reside in a separate TIFF/IT-P1 file set

• Resolutions:

Continuous Tone (CT) = RES 12 dpmm (300 dpi)
Linework File (lw) = RES 80 dpmm (2032 dpi) and should not exceed RES 100 dpmm (2540 dpi). Preferred RES is 100 dpmm.
Note: Final output of all The Physician and Sportsmedicine pages will be at 2400 dpi
