Bleed
Measurement units
Determines the linear units used for the size of pages. You can
select points, picas, inches, centimeters, or millimeters. The
default is points.
Bleed detection
Determines whether the image extends to the bleed box.
Defines the maximum gap that can exist between the trim box
and the bleed box before the image requires bleed.
To adjust the bleed detection, enter the desired values. By
default, bleed detection is turned off.
Check objects that touch the trim box, or objects that almost
touch the trim box (within a certain distance).
Consider image content when deciding if images have sufficient
bleed option to determine if the detection should take into
account the content of images—for example, whether or not
white pixels are acceptable.
You may find that the bleed detection feature works best if you
enter the minimum bleed that is acceptable, rather than the
minimum bleed that is ideal. For example, if you ask designers
to create a 0.125-in. bleed, but find that a 0.0625-in. bleed is
acceptable, the preflight results have fewer messages if you ask
PDF Preflight to look for a 0.0625-in. bleed.
Note: This option can result in slower performance.
Note: The preflight bleed detection feature detects and reports bleed
problems even when the trim box is equal to the media box. For example,
a user might create a file in the QuarkXPress software with <
X
> amount
of bleed, save and export the PDF file with no crop marks, and then
import and refine it with <
X
> amount of bleed preflight detection.

Type
True Type
Determines whether the PDF file contains TrueType fonts.
TrueType fonts are built into Windows and Macintosh
operating systems and print well on both PostScript and non-
PostScript printers.
