Abstract
Overview
ISO 9957-1:1992 specifies requirements and test conditions for water-based India ink intended for use on natural tracing paper. The part focuses on reproducibility and archival performance of drawn lines when used with tubular technical pens and conventional reproduction techniques (blueprint, microfilming, photography, electrostatics). The standard defines test atmosphere, sample preparation, and objective methods to measure line quality and durability.
