Fonts section InDesign embeds a font unless the font vendor has restricted embedding. Embedding prevents font substitution when a reader edits the file and ensures that readers will see the text in its original font. If InDesign cannot embed a font due to the font vendor's settings and someone who opens 109 or prints an Adobe PDF file does not have access to the original font, InDesign temporarily substitutes the font with a Multiple Master typeface: either AdobeSerMM for a missing serif font or AdobeSanMM for a missing sans serif font. Multiple Master fonts can simulate the font metrics and line breaks of the original font so that the overall layout is preserved. Subset Fonts Below: Embed only the glyphs actually typed in the document, based on a threshold percentage. The threshold determines the point at which InDesign embeds all characters for a font. For example, if you change the threshold to 35, InDesign embeds all characters only if more than 35% of the font's characters are used in the file; if fewer than 35% of the characters are used, InDesign embeds only the characters used in the file. For high-resolution output, it's a good idea to subset fonts to ensure that the glyphs used by the document are the ones that will be used by the output device. If font subsetting is not used, output may not be as expected if some glyphs at the output device have subtle differences compared to the glyphs in the font versions used in the document. For this reason, the PDF export preset Press is set to subset all fonts below 100% glyph usage by default.

Transparency Flattener section You can apply a transparency flattener preset when you export to PDF, just as you can when you print.

Fonts section
InDesign embeds a font unless the font vendor has restricted embedding. Embedding
prevents font substitution when a reader edits the file and ensures that readers will see the
text in its original font.
If InDesign cannot embed a font due to the font vendor’s settings and someone who opens
or prints an Adobe PDF file does not have access to the original font, InDesign temporarily
substitutes the font with a Multiple Master typeface: either AdobeSerMM for a missing serif
font or AdobeSanMM for a missing sans serif font. Multiple Master fonts can simulate the
font metrics and line breaks of the original font so that the overall layout is preserved.
Subset Fonts Below:
Embed only the glyphs actually typed in the document, based on a
threshold percentage. The threshold determines the point at which InDesign embeds all
characters for a font. For example, if you change the threshold to 35, InDesign embeds all
characters only if more than 35% of the font’s characters are used in the file; if fewer than
35% of the characters are used, InDesign embeds only the characters used in the file.
For high-resolution output, it’s a good idea to subset fonts to ensure that the glyphs used by
the document are the ones that will be used by the output device. If font subsetting is not
used, output may not be as expected if some glyphs at the output device have subtle differ-
ences compared to the glyphs in the font versions used in the document. For this reason, the
PDF export preset Press is set to subset all fonts below 100% glyph usage by default.
OPI section
The OPI options in the Export PDF dialog box are identical to those in the Print dialog box,
except that there is no OPI Image Replacement option in the Export PDF dialog box. See
“OPI Section” on page 96.
The OPI settings in this dialog box don’t change the settings in the Print dialog box.
Transparency Flattener section
You can apply a transparency flattener preset when you export to PDF, just as you can when
you print. The Transparency Flattener section in the Export PDF dialog box works identi-
cally to the same section in the Advanced panel of the Print dialog box. See “Transparency
Flattener Section” on page 97.
