While there are many tools and ways you can diagnose (and eventually repair) print output related problems, the most common ones are:
- Preview Mode--gives a simplified view that hides any nonprinting objects (Select View>Screen Mode>Preview)
- Overprint Preview--confirms that objects overprint and shows how inks will interact when they are printed on press (Select View>Overprint Preview)
- Flattener Preview--highlights text and other vector content that may rasterize upon output, making the text more bold than it actually is (Select Window>Output>Flattener Preview)
- Live Preflight--catches errors as you're designing your document, a great tool for creatives
