Thanks for the explanation Dave. Since the time you posted the "Aftershock" i was wondering how paper would be kept stable enough during the exposure but now i finally realised that you must have been using negative cutouts, that is the hologram is not of light reflected or shine through paper but light going through the holes cut in paper. That way movement of the paper would not be of critical importance, since movement would only "blur" the edges of the forms.
Movement of the template with the cutouts could even be used creatively to create brightness modulations around the forms.
