ArcScene 2D export settings

[ThomasWicks]

I'm submitting a paper to PlosOne, and have been using ArcScene to produce my 3D mapping. However, I'm struggling to comprehend quite how to meet their image requirements (http://www.plosone.org/static/figureSpecifications#resolution)

They require images to be between 300-600ppi and 6.83 inches wide in Tiff format. I just cant get my head around what settings I need to use to set the Resolution, Width, Height and view size parameters within the 2D export option.

Any suggestions? It cant just be me who has these issues with ArcScenes 2D export issues but have had little luck searching through previous questions!

Many thanks
