Cross-platform issues
While InDesign files and popular graphics formats originating on a PC
can be opened on a Mac (and vice versa), fonts can still be an issue.
Windows-format TrueType fonts can be used under Macintosh OS X,
and OpenType fonts are fully cross-platform. PostScript Type 1 fonts,
however, are platform-specific. Attempting to replace a font with what
seems to be the cross-platform equivalent can easily result in a changed
appearance, or worse, text reflow.
Using a font-conversion utility to convert a PC font to a Mac font (or vice
versa) may result in a font with changed font metrics, which may result
in text reflow. Additionally, you may find that the End User License
Agreement (EULA) for the font forbids such conversions. It is strongly
recommended that you keep files on their original platform unless
you’ve determined that OpenType fonts are used throughout the job.
Managing missing fonts
When you open an InDesign file that’s missing fonts, the Missing Fonts
alert lists those fonts needed by InDesign that are not available. Note,
however, that this initial list does not reference any fonts needed by
placed graphics.
Missing Fonts Alert
When you open an InDesign le that
uses fonts currently unavailable on the
system, you’re presented with an alert
listing the missing fonts. However,
only fonts used by InDesign are listed
in this alert: fonts used in support
artwork are not listed here.
Clicking the Find Font button takes you to the Find Font dialog box, in
which all fonts required by the document itself are listed, as well as fonts
needed by placed art (indicated by an icon). Click the Find First
button to navigate to the first use of the font in the document. (The Find
Font dialog box is available at any time by choosing Type > Find Font.)
Using the Find Font feature
InDesign’s Find Font feature lists fonts
used by InDesign, as well as any fonts
used by placed graphics. Here, a font is
used by a placed Illustrator le, but is
not available on the system. (Illustrator
embeds fonts with suitable
permissions, but won’t embed fonts
that disallow embedding.)
To replace a needed font in the Find Font dialog box, select the font
name in the top window of the dialog box, and then choose a
replacement font family and style in the Replace With fields. Replacing
fonts does not, by default, change style definitions. To do that, check
the Redefine Style option. Keep in mind that replacing fonts will change
the appearance of text and possibly cause reflow. It’s preferable to use
the correct fonts originally specified by the designer, unless you have
been given permission to replace fonts. While you can designate
replacement fonts for text created in InDesign, you cannot replace fonts
in placed graphics; for that, you’ll have to open the artwork in the
originating application and make the change, resave, and update in
InDesign. Again, consult the file’s creator to obtain the correct font, or
permission to substitute an available font. When you preflight a file in
InDesign, the application checks for fonts needed by placed artwork
and reports any missing fonts. When you package a file, InDesign
gathers up all necessary fontsincluding those required by (but not
embedded in) placed artwork, provided that all required fonts are
active on the system.
