About printer marks in PDFs

When preparing a document for print production, you must include various marks to aid the print service provider in aligning separation films, calibrating ink density, and trimming the document correctly. Printer marks show the boundaries of document boxes in Adobe PDF, like trim boxes and bleed boxes.

To add printer marks at the time of printing, use the Marks and Bleeds panel in the Advanced Print setup dialog box. Alternatively, you can permanently embed printer marks in the file using the Add printer Marks dialog box (and optionally in a layer). For adding printer marks only to the printed output, see Include marks and bleeds.

Note

PDFs created from Adobe InDesign CS and later versions can have printer marks in a separate layer or directly on the page. To view these marks in Acrobat, check the Layers tab. If printer marks were exported as a layer, using the Acrobat Add printer Marks feature will replace the InDesign printer marks. However, if printer marks aren’t in a layer, Acrobat printer marks will overlay InDesign printer marks and might not align perfectly.

Embed printer marks in a PDF

  1. From the All tools menu, select Use print production > Add printer marks.

  2. Specify the pages to mark.
  3. Specify the marks and settings.

Set page boxes

You can define the boundaries for trim, bleed, and art when preparing your PDF for printing and other outputs using the Set page boxes feature. Adjust the margins of various document boxes in Adobe PDF, including media (page size), trim, bleed, and art boxes. This feature is helpful if the printer marks you add with the Add printer Marks tool (not the Marks and Bleeds panel in the Advanced Print setup dialog box) would be cut off due to a small crop box.

Print service providers can also use this tool to expand the page size for imposition tasks. You can easily switch between boxes without losing the margins you've set for each. When adjusting individual boxes, the preview in the Set Page Boxes dialog box updates accordingly. For example, if you expand the crop or media box, the page content in the preview "shrinks" to reflect the changes.

To access Set page boxes dialog, from the All tools menu, select Organize pages > Set page boxes. 

Note

When the crop box is expanded, the media box adjusts accordingly.

Page Boxes dialog box
Set Page Boxes dialog box lets you set boundaries for trim, bleed, art, and page size

Fix hairlines

Hairlines, which are thin lines, can cause issues in offset printing. If you keep them as they are in PDFs, they might not show up in the printed output. The Fix hairlines tool can detect and replace most hairlines with thicker lines to avoid this problem.

  1. From the All tools menu, select Use print production > Fix hairlines.

  2. In the Fix hairlines dialog that opens, enter a width for the hairline you want to find, and enter a replacement width.

    Fix Hairlines dialog box
    Adjust hairline widths using increment arrows. Shift-click arrows to change widths by whole integers.

  3. From the Units drop-down list, select the unit of measurement.

  4. Optionally, select Include Type3 Fonts or Include Patterns to replace hairlines in Type 3 characters or patterns with the same replacement width as other hairlines.

    Font characters and patterns can appear in different contexts within the same document, like using different magnification values. Changing the line width might lead to unexpected outcomes. It's essential to review the results when selecting these options and make necessary adjustments accordingly.

  5. Specify the pages to check and select Ok.
