A few years ago when I went slightly insane testing over a 100 different bottles of fountain pen inks, I eventually realized that there was an important variable that I hadn’t addressed in my reviews.
As I sit here with 88% humidity, it’s making me think that ink would almost have to react differently when applied to paper in extreme dry or humid environments – though I’m certainly not qualified to explain it.
I distinctly remember certain times when my ink (not specific to brand or color that I can remember) dried quickly on the page yet later smeared – a phenomenon that has been attributed to the top ink molecules drying faster than the bottom ink molecules. And when might that happen? It didn’t happen for me all of the time and I never really looked hard enough at whether it was a *wet writer” “cheap paper” or humidity that might be causing this to happen.
