Tiff or
Tif:
Tag
Information file format. This is the best way to save a
file for printing. The tiff format does not compress the image
so it doesn't have any losses when we go to print the file. This
provides the best quality output.
Eps:
Encapsulated Post Script. Most raster based (Photoshop) or
vector based (Illustrator) programs allow for saving as an eps
file. EPS files work very well for printing as long as you
do not place an eps image in a file and then save that file as
an eps. (Embedded eps files do not print).
Pict:
The PICT format is widely used between Macintosh page layout and
graphics applications as an intermediary file format used for
transferring documents between applications. The PICT
format is especially effective at compressing images that
contain large, flat areas of color.
Jpg:
Joint Photographics Experts
Group (JPEG) compression economizes on the way data is stored
and also identifies and discards "extra" data, that is,
information beyond what the human eye can see. Because it
discards data, the JPEG algorithm is referred to as "lossy."
This means that once an image has been compressed and then
decompressed, it will not be identical to the original image.
Because of this problem we do not prefer using this format.
Gif:
Graphics Interchange Format
file. The GIF format is commonly used to pass documents
between computers. This is a highly compressed format (using LZW
compression) that is designed to minimize file transfer time
over phone lines. GIF format only supports 8 bit color (256
different colors).
