Importing, exporting, and saving
The Marks & Bleed area of the Save Adobe PDF dialog box lets you specify the extent of the bleed and add a variety of
printer’s marks to the file.
All Printer’s Marks Enables all printer’s marks (Trim Marks, Registration Marks, Color Bars, and Page Information)
in the PDF file.
Printer Mark Type Lets you choose Roman printer’s marks, or Japanese marks for pages printed in Asian languages.
Trim Marks Places a mark at each corner of the trim area to indicate the PDF trim box boundaries.
Trim Mark Weight Determines the stroke weight of the trim marks.
Registration Marks Places marks outside the artboard for aligning the different separations in a color document.
Offset Determines the distance of all printer’s marks from the edge of the artboard. The trim marks are at the edge of
the space determined by the offset.
Color Bars Adds a small square of color for each spot or process color. Spot colors converted to process colors are
represented using process colors. Your service provider uses these marks to adjust ink density on the printing press.
Page Information Places page information outside the artboard of the page. Page information includes the filename,
page number, current date and time, and color separation name.
Use Document Bleed Settings uses the document’s bleed settings instead of the bleed settings in this dialog box.
Bleed Top, Bottom, Left, Right Controls the bleeds for the artwork. When the button is selected, these four values
are proportional—editing one will update the values in the other three.

Color management and PDF/X options for PDF
You can set the following options in the Output section of the Save Adobe PDF dialog box. Interactions between
Output options change depending on whether Color Management is on or off and which PDF standard is selected.
Color Conversion Specifies how to represent color information in the Adobe PDF file. When you convert color objects
to RGB or CMYK, also select a destination profile from the pop-up menu. All spot color information is preserved
during color conversion; only the process color equivalents convert to the designated color space.
• No Conversion Preserves color data as is. This is the default when PDF/X-3 is selected.
• Convert To Destination (Preserve Numbers) Preserves color numbers for untagged content in the same color space
as the destination profile (by assigning the destination profile, not converting to it). All other content is converted to
the destination space. This option is not available if color management is turned off. Whether the profile is included
or not is determined by the Profile Inclusion Policy.
• Convert To Destination Converts all colors to the profile selected for Destination. Whether the profile is included
or not is determined by the Profile Inclusion Policy.
Note: When Convert to Destination is selected, and the Destination doesn’t match the document profile, a warning icon
appears beside the option.
Destination Describes the gamut of the final RGB or CMYK output device, such as your monitor or a SWOP
standard. Using this profile, Illustrator converts the document’s color information (defined by the source profile in the
Working Spaces section of the Color Settings dialog box) to the color space of the target output device.
Profile Inclusion Policy Determines whether a color profile is included in the file.
