TIFF Files
A Tagged Image File
Format (TIFF) file is the most widely used file format in desktop
publishing today. It is a raster-based file that supports the
following:
RGB
CMYK
Grayscale
Lab
Indexed color
TIFF files can be compressed
by using an LZW lossless compression approach or JPEG lossy compression.
For high-end print production, it is the best practice to use
either LZW compression or a very small amount of JPEG compression.
The JPEG compression approach is a lossy compression that will
degrade image quality when used in large amounts.
When placing a TIFF
file on a page, any clipping path that has been defined
can be retained and applied. However, Photoshop's Alpha
channel information will not be translated when placing
a TIFF.
