Abstract

Prints from hologram masters are provided by using a collimated light source of relatively short wavelength such as an ultraviolet lamp or laser. The ultraviolet light source is collimated by a lens. The resultant beam is used to generate a contact print from the original hologram. While the use of an ultraviolet source is convenient, any source, including X-rays, having a wavelength substantially smaller than the width of the holographic grating of the holographic master can be used.
