See Where Shadow Detail is Lost in Acrobat

Acrobat’s Output Preview dialog box lets you check the reproduction of shadow detail. Choose Advanced> Print Production> Output Preview and turn on the Total Area Coverage option.

Now you can use the % field located to the right of the checkbox to select the total in percentage for the press and paper you’re printing on.

You can use the following total ink values as a guideline: Coated Stock: 300-340; uncoated stock: 280-300; and newsprint stock: 240-260.

Any areas in your image that contain ink total volumes exceeding your numeric value will be highlighted in bright green.
