Notes about Graphics File Formats
Each logo on this site is available in five versions: PowerPoint
JPEG, Vector EPS, high-resolution RGB TIFF, low-resolution
RGB JPEG and Indexed-color GIF.
PowerPoint JPEGS are 150 dots per inch (dpi)
RGB graphics saved as high-quality JPEGs. They load fast on
screen, but contain enough resolution to avoid the jaggies
both on screen and on your inkjet or laser printer. These
JPEG images are suitable for both Mac OS and Windows PowerPoint.
EPS (Encapsulated PostScript) is the preferred
format for use in high-quality offset printing. EPS files
are scaleable without loss of resolution, and retain color
separation specifications. EPS files also have transparent
backgrounds. IIT EPS logo files are saved with a color TIFF
preview supported by both Mac OS and Windows graphics applications.
TIFF (Tagged Image File Format) logo files
are 300dpi RGB images. These files contain an alpha channel
(where appropriate) for use in video production. These logos
are not recommended for offset printing; instead, use EPS
format. TIFF files on this site are suitable for Mac OS and
Windows graphics applications.
JPEG logo files are 72dpi (screen resolution)
RGB images. They are optimized for cross-platform use on the
Internet.
GIF logo files are 72dpi (screen resolution)
indexed-color images. They are optimized for cross-platform
use on the Internet. IIT GIF images have a transparent background
(where applicable) and a matte color of white.
