Printing Mood boards and the large margins don't look nice

The mood boards look great when in the digital format!! We work with clients who like to also have physical samples on a printed mood board. When you download to print the boards, it creates a large margin that honestly takes away from the look and they look terrible… Would like the option to be able to change the settings on the downloads to not look like the mood board has been shrunk down on the page and now has too much space around the edges.
