TS ISO 6196-5

TS ISO 6196-5 is a vocabulary standard for micrographics, focusing on terms and definitions related to image quality, legibility, and inspection. Its purpose is to normalise the language used for these concepts and to clarify how the entries relate to one another, so that people working with micrographic records can use the same technical terms consistently.

Image quality and legibility in micrographics

Micrographics is concerned with recording documents or records at reduced size on an optical medium for later viewing and retrieval. In this context, image quality is generally associated with factors such as clarity, contrast, sharpness and the faithful presentation of detail. Legibility refers to whether text, symbols and linework in the recorded image can be reliably distinguished by a human reader. The standard’s role is to define the terminology around these ideas; it should not be read as introducing a separate set of numerical acceptance limits or a detailed test procedure on its own.

Why inspection terminology matters

Inspection is a key concept when micrographic records are checked for defined characteristics and suitability. Clear terminology supports archival practice, quality assurance and document management by ensuring that different users mean the same thing when they discuss image assessment. The distinction between image quality and legibility is especially important: an image may appear technically acceptable yet still fail to deliver readable document content. This part of the vocabulary provides a common technical language for that distinction.
