Ink Decay Modeling

Simulate the half-life of various ink formulations under different environmental conditions based on our longitudinal spectral analysis data.

JAVASCRIPT DISABLED: Interactive modeling requires JavaScript.

Summary Data:

Sharpie (Felt-tip): High UV sensitivity. Unprotected exposure halves spectral integrity in ~4 years.
Ballpoint (Oil-based): Moderate sensitivity. Halves in ~12 years.
Iron Gall (Historical): Highly resistant to UV, but degrades substrate over decades.
