Here’s a quick and easy guide on how to clear background tasks via Preflight in Adobe InDesign:
- To clear a background task via Preflight in InDesign, open the Preflight panel by going to the top menu and selecting 'Window' → 'Output' → 'Preflight.'
- Once the panel opens, disable Live Preflight by unchecking the box next to On.
- Preflight is now disabled, preventing InDesign from constantly checking the document for errors, which effectively cancels the background preflight process.
