It doesn't set up hard like nail polish.
Dice, that is an interesting observation. I know a LOT of, especially, Atlas books from the 50's, often exhibit absolutely blinding richness of the inks. I tend to attribute this to an ink combination that had some VERY dense coverage (like a 100M/100C) etc. But adding the potentail for the inks to setup "hard like nail polish" makes me think back to my gem cutting days. The harder the stone, the brighter the polish. A soft stone never could really produce a mirror finish. Turquoise, for example, can be on the flat side. But the turquoise from tibet, where the mineral was impregnated with silicone, resulting in a very hard stone, took an amazing polish.
I have to wonder if this aspect of the ink's setup qualities, in combination with dense coverage, could have produced those incredibly deep and highly REFLECTIVE qualities?
Comic book people are interesting people.
