Chapter 20. Standards for Microfilming Public Records

Part I
Authority

17VAC15-20-10. Authority.

These standards are established by the Library Board in accordance with the provisions of the Virginia Public Records Act, Chapter 7 (§ 42.1-76 et seq.) of Title 42 of the Code of Virginia.

Statutory Authority

§§ 42.1-8 and 42.1-82 of the Code of Virginia.

Historical Notes

Derived from VR440-01-137.1 § 1.1, eff. July 9, 1986.

Part II
Scope

17VAC15-20-20. Scope.

These standards apply to all records that have administrative, legal, fiscal, or historical value as defined in § 42.1-77 of the Code of Virginia and to the procedural microfilming process used in the circuit court clerks' offices. Such determinations are included in the officially approved retention and disposition schedules. When the informational contents of such public records are to be maintained on microfilm, the silver-gelatin camera microfilm produced by source document methods is to be considered the permanent archival security copy. For Computer Output-Microfilm, refer to Standards For Computer Output Microfilm (COM) For Public Records (17VAC15-50-10 et seq.). Thermally processed or TEP film shall not be used. The camera microfilm shall not be used for reference purposes.

When disposal of the original permanent public record (identified as such in the state retention and disposition schedule) is recommended after microfilming, the camera negative must first meet these standards and conform with The Library of Virginia's "Guidelines for Accepting Microfilm, Microfiche or Optical Media for Security Storage at The Library of Virginia," dated November 1999. Upon receipt of the camera negative for storage with The Library of Virginia (LVA), it will be inspected, approved and accessioned by the Imaging Services Branch, Records Management &; Imaging Services Division. If the film fails to meet the requirements, it will be returned to the office of origin.

Statutory Authority

TABLE 1. BACKGROUND DENSITIES.

Classification

Description of Documents

Density

Group 1

High quality, high contrast documents or printed material and black typing; fine line originals, black opaque pencil writing and documents with small high contrast printing; Pencil and ink drawings, faded printing and very small printing.

1.00‑1.20

Group 2

Low contrast manuscripts and drawings; graph paper with pale, fine-colored lines; letters typed with a worn ribbon; poorly printed, faint documents; and positive appearing photostats and blueprints.

0.80‑1.00

Background density on positive appearing camera microfilm shall be no higher than 0.30. The base-plus-fog density of unexposed, processed, clear-base film must not exceed 0.10. When a tinted base film is used, the density shall not exceed 0.30. Measurements are made using a densitometer calibrated with a step tablet provided by the Imaging Services Branch, LVA. In certain instances, some poor contrast documents may require lower densities to make the entire image legible and reproducible as stated in ANSI/AIIM MS23 – 1998. Mixed quality documents should be filmed at the lower densities. A system of inspection and quality control to ensure compliance with this standard shall be established and consistently maintained in conformance with ANSI/AIIM MS23 – 1998 Practice for Operational Procedures/Inspection and Quality Control of First-Generation, Silver-Gelatin Microfilm of Documents.

17VAC15-20-80. Minimum resolution.

A minimum resolution of 90 lines per millimeter shall be obtained regardless of reduction ratio used or the type of camera used and the 4.0 pattern shall be resolved for 16mm microfilm and the 6.3 pattern for 35mm microfilm. This shall be determined by the line count and direction method using the National Bureau of Standards Standard Reference Material 1010a (ANSI and ISO Test Chart No. 2) (or equivalent) for planetary cameras and the AIIM MS-113 Test Chart (or equivalent) for rotary cameras. No other test charts shall be used unless approved by the LVA. The test charts are composed of two groups of five parallel line pairs, the line pairs in the two groups being oriented perpendicular to one another, and each pattern is numbered and progressively reduced. Five vertical and five horizontal line pairs shall be clearly defined in both directions. The resolution test chart shall be photographed at the beginning and at the end of each reel of camera microfilm at least three times in succession.

NOTE: Resolution of duplicates should generally be only one pattern lower than the original from which the duplicate was reproduced. Pattern resolved times the reduction ratio equals lines per millimeter.

Resolution requirements for procedural microfilm recording. A minimum resolution of 120 lines per millimeter shall be obtained regardless of reduction ratio used or the type of camera used and the 5.0 pattern must be resolved for 16mm microfilm or the 3.2 pattern for 16mm microfilm being generated by the same office using digital imaging as a recording process. This shall be determined by the line count and direction method using the National Bureau of Standards Standard Reference Material 1010a (ANSI and ISO Test Chart No. 2) for planetary cameras and the AIIM MS-113 Test Chart for rotary cameras. No other test charts shall be used unless approved by the LVA.

17VAC15-20-160. Splicing.

Splicing is not permitted on the camera negative, except at the beginning of the reel before all beginning targets but after the clear leader. Splicing can be done in place on the intermediate master up to a total of five splices. An unexposed area of film shall be used between the splice and the beginning titling targets. Ultrasonic splicing is recommended for polyester film.

NOTE: Due to the required filming procedures, more than five splices within a single 16mm reel are permitted for procedural microfilming.
