No doubt missed the obvious setting and this may say more about my workflow than any issue but...
Creating an eps file with a transparent background (for use in other page layout software) gives the checkerboard background, which is fine, but slightly distracting, I prefer a clean canvas look. Could there be/is there a way of selecting a colour e.g. white for the canvas only whilst retaining the transparent property of an exported file?
My workaround at the moment is to have a layer with white fill switched on for working/switched off for export - which I easily forget to switch off before exporting! :-/
