Vector
Graphics vs. Raster Graphics
Which one is best to use, and when?
There
are three important things to remember
about fonts and graphic projects.
First, find out which
platform was used to create the graphic
file. The Mac platform and the PC platform
have different font files. Font files
from the Mac will not work on a PC and
vise versa. The reason for this is the
Mac uses Type 1 fonts (postscript) and
the PC uses True Type fonts and PC designed
Type 1 fonts. If you place Mac fonts
into a PC font directory, the font will
not function in the PC graphic software
packages, you might even get an error.
Determining which platform was used
to create a project is essential. For
example, if a Mac platform Adobe Illustrator
file is opened on a PC platform, the
PC version of Adobe Illustrator will
open the file with the system's default
or substitute fonts, making the layout
look very different. Many software packages
are smart enough to warn the user about
missing fonts, but some will not. The
latter will create headaches.
Second, insure that
all font files used in the project are
sent with the graphic file. There are
hundreds of font files in existence
and no computer has them all on its
system. If a font is missing the computer
will substitute it with a default font
and the layout will be wrong. This will
slow down the preflight process because
the client has to be contacted and the
font files sent for a proper preflight
and output.
Third, if you are
uncomfortable with sending the font
files, or do not know how to gather
and include them with a project, convert
the fonts to outlines. Converting the
fonts to outlines changes all the letters
and characters in a graphic to individual
elements (vector or raster depending
on the software package, see Vector
Graphics vs. Raster Graphics for
more information). Software packages
such as Adobe Illustrator and Corel
Draw have this function and Adobe Photoshop
can rasterize the font. Please note
that Quark Express does not have the
ability to convert fonts to outlines,
all fonts must be collected.
There are programs
available that will embed the fonts
within the file but it is still proper
practice to follow the three steps mentioned
above.
