File Formats & Descriptions

EPS  (Vector File)

Encapsulated PostScript (EPS) language file format can contain both vector and bitmap
graphics and is supported by virtually all graphic, illustration, and page-layout programs. EPS
format is used to transfer PostScript-language artwork between applications. We recommend
EPS graphics for vector and bitmap images.


TIFF

Tagged-Image File Format (TIFF) is used to exchange files between applications and computer
platforms. TIFF is a flexible bitmap image format supported by virtually all paint, image-editing,
and page-layout applications. Also, virtually all desktop scanners can produce TIFF images. We
recommend TIFF graphics for bitmap images.


JPEG

Joint Photographic Experts Group (J PEG) format is commonly used to display photographs and
other continuous-tone images in hypertext markup language (HTML) documents over the World
Wide Web and other online services. JPEG format supports CMYK, RGB, and Grayscale color
modes, and does not support alpha channels. Unlike GIF format, JPEG retains all color
information in an RGB image but compresses file size by selectively discarding data. Due to the
fact the the JPEG format discards data, we do not recommend it for any images. If you must use
the JPEG format, please make sure all quality settings are at their maximum and the resolution is
at least 300 dpi.


BMP

BMP is a standard Windows image fonnat on DOS and Windows-compatible computers. BMP
format supports RGB, Indexed Color, Grayscale, and Bitmap color modes, and does not support
alpha channels. We DO NOT recommend the BMP format for any images.


PICT

PICT format is widely used among Mac OS graphics and page-layout applications as an
intermediary file format for transferring images between applications. PICT format supports
RGB images with a single alpha channel, and indexed-color, grayscale, and Bitmap-mode
images without alpha channels. PICT format is especially effective at compressing images with
large areas of solid color. This compression can be dramatic for alpha channels with their large
areas of white and black. We DO NOT recommend the PICT format for any images.


GIF

Graphics Interchange Format (GIF) is the file format commonly used to display indexed-
color graphics and images in hypertext markup language (HTML) documents over the World
Wide Web and other online services. GIF is an LZW-compressed format designed to minimize
file size and electronic transfer time. GIF format preserves transparency in indexed-color images;
however, it does not support alpha channels. We DO NOT recommend the GIF format for any printed images.
