CONTACT PRINTING APPARATUS AND METHOD Abstract of the Disclosure Apparatus and method are disclosed for contact printing information from a master record carrier onto a replicate material of a type that emits gas during the con- tact print exposure (e.g., a diazo-film emulsion). It has been discovered that the emitted gas acts as an efficient lubricant of the master-replicate interface and contributes to relative movement between the master record carrier and the replicate material during the contact print exposure. In the case of videodisc replication, wherein video information is recorded in the form of billions of micron-sized apertures, such relative movement severely degrades the replicated imagery. To limit such relative movement, a preferred em- bodiment of the present invention provides contact printing apparatus, including a specially filtered exposing source, that substantially eliminates relative movement between the master record carrier and the replicate material.
