ABSTRACT:
A technique for fixedly positioning a holographic recording laminate relative to a master hologram including the steps of inducing a electrostatic charge on the holographic recording laminate and positioning the recording laminate in close proximity to the master hologram such that the electrostatic charge on the recording laminate causes a static attraction between the recording laminate and the master hologram that retains the recording laminate in a fixed position relative to the master hologram.
