The EPS allows you to open the file in an image editor application at a desired resolution, then you can save a TIFF from there.
I am curious as to why one can't set the tiff resolution within plotmaker (and archicad itself). Is there a reason why not or just that this has yet to be included?. This is possible for jpgs.
