If you need to add common objects to your slides (such as logos, headers and footers), master slides are just the ticket. Instead of manually copying and pasting these common objects to your slides, you can add them to a master slide. After that, it’s a simple matter of applying the master slide to selected project slides.
Each new Adobe Captivate project contains one Main Master Slide and multiple Content Master Slides. You can format the Main Master Slide, format the existing Content Master Slides, or create your own Content Master Slides.
