I’m searching for an answer about UV-blocking.
On a digital negative under UV light, the greenish halftone dots appear denser that black halftone dots would - but the film base between the dots remains neutral and transparent. UV-resistant colour is added to correct an inkjet/media deficiency. Right?
A regular negative developed in PMK acquires a sepia fog which blankets everything: continuous-tone silver particles and film base together - in equal proportion.
What does this UV-resistant fog correct that a more dense negative would not correct?
