Change Overprint InDesign
Script for Adobe InDesign
Change the overprint of all elements, selected elements, or all on a selected layer.
- Change fill or stroke or both
- Set overprint on or off
- Adapt open source to customize or create other scripts
For the Illustrator version of this script, see Change Overprint.

How to use the script
The interface has two sections: Scope, and Overprint. Click the OK button and elements are modified as directed.
Section 1: Scope
All — every element throughout the document are affected.
Selected — only the currently selected elements are affected.
Layer — elements on the selected layer are affected. In the drop-down list, choose the desired layer.
Section 2: Overprint
Fill overprint — enable and select On or Off to change the fill overprint of elements. Disable and the fill overprint of all elements remains unchanged.
Stroke overprint — enable and select On or Off to change the stroke overprint of elements. Disable and the stroke overprint of all elements remains unchanged.
Regarding overprint
When told to overprint fill or stroke, and the item color is either zero percent CMYK or otherwise equivalent to “white” or “paper”, the script does not enable overprint, and when done, alerts the user “Items with no color (white) were not set to overprint.” This behavior is to prevent inadvertently overprinting white, which results in an invisible element once printed.

IMPORTANT: scripts are developed for the latest Adobe Creative Cloud applications. Many scripts work in CC 2018 and later, even some as far back as CS6, but may not perform as expected, or run at all, when used in versions prior to 2018. Photoshop features Select Subject and Preserve Details 2.0 definitely fail prior to CC 2018 (version 19) as the features do not exist in earlier versions. For best results use the latest versions of Adobe Creative Cloud applications.
