The inside and outside margins can be adjusted in your theme settings under Print Layout.
You can make changes to your theme on the Formatting Tab by clicking the three dots next to the theme name and selecting Edit or Edit as New Theme.
Margins in Atticus are only adjustable by .125in increments, so you’ll want to use the up/down arrows to the right of the field to nudge the margin settings up or down.
For more details on how to set up or adjust your theme settings, you can refer to this tutorial: https://www.atticus.io/create-a-custom-theme/ It provides detailed instructions and tips on creating and modifying your theme.
