SMI's archive and book microfilming conform to the following specifications: Preparation: - Prior to microfilming, documents are throroughly checked for completeness, condition and chronological order. Filming: - The master microfilm is a 35mm, high-contrast Kodak silver halide polyester base film manufactured to ANSI, NEH, and Federal Standards. - The minimum resolution (the camera's ability to record fine detail) is 110 lines per mm. Archives and books are filmed in a standard two page per frame format, (unless otherwise requested), at a reduction ratio not exceeding 20:1. Targets That Appear On Each Roll of Film: - Start of roll.....Marks the beginning of each roll of film. - Resolution test (two targets).....Checks the camera's focus. - Density (three targets).....Used to check the contrast of the microfilm image to assure maximum readability prior to duplicating. - Notice of Omission Responsibility.....Indicates SMI microfilming policy. - Notice of Best Copy Available.....Advises of poor contrast, smeared ink, bleed through and other printing anamolies. Indicates that no better copy is available. - Certificate of Authenticity.....A certificate signed by the camera operator, attesting that the document microfilmed is genuine. - End-of-roll.....Marks the end of each roll of film. Inspection: - After each master negative roll has been processed it is inspected twice. First mechanically to insure that the resolution (focus) and density (contrast) specifications are met and then visually, to insure that every page is in focus, that no pages are missing and that the pages are in chronological order. Storage: - The preservation master negatives are stored in preservation quality, vented film containers and maintained in our climate controlled and CCTV monitored facilities. The longevity of all master microfilm is further assured because of our flat storage vault slotting. For additional information phone 1-800-367-1273 or contact us by email at: |
