How to reduce ink levels using Acrobat's Touch-Up Object Tool

Open your PDF in Acrobat. Then go to Tools > Print Production > Output Preview.

In the dialogue box below (under Total Area Coverage) enter the recommended Maximum Ink Limit for the paper stock you reqire (225% for Uncoated stocks such as Letterheads and 300% for Coated stocks such as Gloss Leaflets).

This tool will then highlight the areas within the document that exceed this limit (100C, 100M, 100Y, 100K = 400%).

To edit an image, select Edit Object (under Content) then right click the image to select Edit Image... (see below). This opens the image in Photoshop.

Once the image is opened in Adobe Photoshop select Edit > Colour Settings then under Working Spaces - CMYK select Custom CMYK..

Coated (300%)

UnCoated & Large Format (225%)

Copy the screenshot below for UnCoated Paper Stocks.

Applying your Colour Settings...
