TS 2722

TS 2722 is a standard concerned with how document sheets of uniform size are arranged on transparent A6 microfiche, defining the No. 1 and No. 2 image layouts. Its subject is the orderly placement of reduced document images on microfiche so they remain dimensionally consistent and usable for retrieval and reading.

Microfiche layout and image quality

Microfiche is a microform medium used to store many document images on a single transparent carrier. The A6 format refers to the physical size of the fiche, while the No. 1 and No. 2 arrangements describe the image placement pattern. This distinction matters because image position, spacing and layout affect storage density as well as later viewing and legibility. According to the title and scope, this standard covers negative or positive transparent microfiche and the rules for arranging same-size document sheets on that A6 fiche.

Technical context of use

In general technical practice, microfiche systems were used for long-term preservation, duplication and cataloguing of printed records. Image quality is commonly associated with legibility, contrast, sharpness and accurate positioning. Standards in this area help keep fiche production consistent across different preparation and archiving workflows. TS 2722 brings together the essential layout and size rules for this type of microfiche arrangement, supporting uniform document presentation.
