PRINT PRODUCTION FORMATS (continued)
TIFF or TIF (Tagged
Image File Format)
TIFF is a common bitmap image format. Most image-editing software and
page-layout applications support TIFF images up to 2GB in file size. TIFF
supports most color modes and can save images with alpha channels. While
Photoshop can also include layers in a TIFF file, most other applications cannot
use these extended features and see only the combined (flattened) image.
EPS (Encapsulated
PostScript)
EPS files may contain both vector and bitmap data. Because it is a common file
format used in print production, most graphics software programs support the
EPS format for importing or placing images. EPS is a subset of the PostScript
format. Some software applications cannot preview the high-resolution
information contained within an EPS file, so Photoshop allows you to save a
special preview file for use with these programs, using either the EPS TIFF or
EPS PICT option. EPS supports most color modes, as well as clipping paths,
which are commonly used to silhouette images and remove backgrounds.
Photoshop PDF
Photoshop PDF files are extremely versatile, as they may contain bitmap and
vector data. Images saved in the Photoshop PDF format can maintain the
editing capabilities of most Photoshop features, such as vector objects, text,
and layers, and most color spaces are supported. Photoshop PDF files can also
be shared with other graphics applications, as most of the current versions of
graphics software are able to import or manipulate PDF files. Photoshop PDF
files can even be opened by users with the free Adobe Reader software.
VIDEO PRODUCTION FORMATS
TIFF or TIF
See Print Production Formats, above.
TARGA (Truevision
Advanced Raster
Graphics Adapter)
This legacy file format is used for video production. The TARGA format
supports millions of colors, along with alpha channels.
Choosing a file format
In this section, you will save your i le to share online and for printing. You will use two
common formats, JPEG and Photoshop PDF.
Saving a JPEG file
To save a copy of your image for sharing online, whether on a web site or to send through
e-mail, you will save it using the JPEG i le format. In this lesson, you will use the
Save menu, but in Lesson 12, “Creating Images for Web and Video,” you will discover
additional features when saving i les for use online, including how to use the Save for Web
feature in Photoshop.
