At a Glance
Micrographics Data 35mm Positive film is a polarity reversing Silver Halide print film designed to make extremely high quality copies from source document originals.
Key Technical Advantages
- Polarity Reversal: Unlike standard films that might maintain the same polarity, this film is engineered to flip the image. In micrographics, if your master archive is a negative (white text on black), this film produces a positive (black text on white), which is much easier for human eyes to read on a microfilm reader.
- Gray Scale Fidelity: Many high-contrast document films struggle with "half-tones" (shades of gray). This film features an emulsion designed for Excellent Gray Scale Reproduction, meaning it can capture the nuances of photographs or wash drawings found within historical documents, not just sharp black-and-white text.
- LE500 Rating: The film meets LE500 (Life Expectancy 500) standards. This indicates that when processed and stored correctly, the images are rated to last at least 500 years, meeting the highest tier of archival permanence.
