Digital page layout for print combines raster and vector graphics and ele-
ments of typography within the framework of print documents, including yers
and posters, brochures, magazines and newspapers, manuals, reports, corpo-
rate identity pieces, CD and DVD jackets, and books. Multipage publications
typically require the use of page layout tools. InDesign is an application used for
digital page layout; QuarkXPress is another page layout application. These pro-
grams’ powerful typography and page setup tools facilitate graphic and publica-
tion design with type and images.
In digital page layout, images are combined with text on the page using
image and text boxes—or frames—that act as containers for content. These
text and image containers are arranged in a composition and then output.
Before page layout occurs, images and graphics are typically created, pre-
pared, and output from raster and vector programs such as Photoshop and
Illustrator. Photos are scanned and retouched, logos and line art are drawn, and
text with special effects is created to develop content elements, which are the
building blocks of a composition. Images in .eps, .tif, or .jpg format are placed in
the page layout program in frames (InDesign) or picture boxes (XPress).
If you have a non-PostScript printer, such as an ink-jet, use .tif les, which
output at the highest available quality. Files in .eps format can only be printed
at high quality on PostScript printers, such as laser printers, high-end ink-jet
poster printers, and commercial imagesetters. All raster les should be 300
ppi to scale, and you should avoid scaling or rotating raster graphics in the page
layout program: doing so will cause a loss of resolution and adversely affect the
image quality. Using .jpgs for print is not recommended because the format’s
poor compression algorithm causes quality loss when the le is decompressed
and printed. Use .jpgs only for low-resolution output to desktop printers and, of
course, for Web and screen design.
Files for print output generated in a raster or vector application and then
placed in a page layout program must use the CMYK or spot color (Pantone)
color models; RGB color is never used for print output and will cause printer out-
put problems. CMYK or Pantone must also be used for text and other elements
(boxes and rules) in the page layout application. Using these color models for
print output helps ensure consistent color from the computer to the color proof
to the nal printed piece.
When you work in a page layout program, the graphics you work with are
low-resolution representations used for placement only. When the le prints,
