Identifying high ink coverage area (Specle)
Before repairing the ink coverage, locate where the high ink coverage is on the file. You can do this by either generating a visualiser report in Specle or opening the PDF on Adobe Acrobat.
To locate high ink coverage via Specle, go to the job page and click on Generate Visauliser Report. After a few seconds, the page will refresh, and a PDF will be created.
Click on Visauliser Report to see a breakdown of all the colours on the file, including image resolution and spot colours.
Identifying high ink coverage area (Adobe Acrobat)
To locate high ink coverage on Adobe Acrobat, open the PDF on Acrobat and search for Output Preview in the Search Tools Bar.
Make sure Total Area Coverage is ticked, and that the value matches the publisher's specification limit. Here, Acrobat will highlight all areas above the specified value.
Alternatively, you can click on Window > Output > Separations Preview in InDesign, then select Ink Limit from the dropdown and enter the ink coverage that matches your error message.
Fixing ink coverage errors on Photoshop (image):
If it is an image that is causing the error, please open the image(s) with ink coverage errors in Photoshop.
1. Click on Edit > Color Settings. Make sure to set the Settings to "Custom".
2. Set the CMYK to "Custom CMYK" and set the Total Ink Limit to the required value.
When exporting on InDesign, set the PDF Standard to PDF/x-4: 2010. Set the Destination to the required ICC Profile. Additionally, please ensure that the colour conversion is set to "convert to destination (preserve numbers)".
Fixing ink coverage errors on InDesign (block colour):
If a block colour is causing the ink coverage error, this could be in relation to how the colours have been made. For example, if the colour is set to 90C 80M 70Y 60K, its total ink weight is 300% (90+80+70+60 or cyan+magenta+yellow+black). Please double-click on the swatch in InDesign and change the CMYK colour values so that the total is less than the maximum ink coverage of the publication you are supplying to (this will be specified in your error message).
