Duplication Services:We offer the duplication of microfilm and microfiche on the following media types: Diazo Film (Roll):Diazo Roll Microfilm Duplicates are produced on our high speed Ozalid 16/35 HSD duplicators. These duplicators are recognized as top of the line production units. Averaging about 75 feet per minute, they both expose and process the Diazo film using Ammonia development. The average life expectancy is 100 years in storage. Diazo is an economic way to reproduce microfilm. The lack of the use of silver in the emulsion layer allows for a lower cost product.
Diazo Film (Microfiche):Diazo Microfiche Duplicates are produced using a Datagraphix 2000 that exposes, processes and collates as it goes. The life time expectancy is the same as the 16mm and 35mm. Diazo is especially useful in this format, as microfiche is usually being constantly updated, because the cost to reproduce a fiche as it has images added is less than the cost to re-film and create a new microfiche.
Silver Film (Roll):Silver Roll Microfilm Duplicates are reproduced with an Extek silver rollform duplicator and then processed to archival standards using an Allen F-10 deep tank processor. The average life expectancy is 300 years in storage. Silver film is the most permanent way to reproduce microfilm, with a long shelf life and chemical stability, it has been the standard in the film industry from its infancy.
Long term storage is qualified as less than 50% relative humidity and not more than 78 degrees, but not less than 50 degrees. |
