Mark and bleed options for Adobe PDF
Bleed is the amount of artwork that falls outside of the printing bounding box, or outside the crop marks and trim
marks. You can include bleed in your artwork as a margin of error—to ensure that the ink extends all the way to the
edge of the page after the page is trimmed or to ensure that an image can be stripped into a keyline in a document.
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 crop area 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 crop area of the page. Page information includes the file
name, page number, current date and time, and color separation name.
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.
