Thanks, Poly.

I'm a bit hesitant to do this as roll film is on a different base to sheet (roll's on a 100 microns thick poly base, while the sheet's on 175 microns). No idea if this makes a difference, but testing's about controlled results, so I don't really want to have a somewhat erroneous starting point...
