You can switch between boxes without losing the margins you set for each. As you adjust individual boxes, the preview
in the Crop Pages dialog box is redrawn to reflect the new settings. For example, if you expand the crop or media box,
the page content “shrinks” in the preview.
Display the Crop Pages dialog box by choosing Document > Crop Pages.
Note: When the crop box is expanded, the media box adjusts accordingly.

Fix hairlines
Very thin lines, called hairlines, are problematic in offset printing. If left as is in PDFs, they might not appear in the
final printed piece. The Fix Hairlines tool can find most hairlines and replace them with a heavier-weight line.
1 Choose Advanced > Print Production > Fix Hairlines, or select the Fix Hairlines tool on the Print Production
toolbar.
2 Enter a width for the hairline you want to find, and enter a replacement width.
