This is a quick post for Joshua, who commented on Twitter about how poorly Day Timer pages take fountain pen ink with his medium-nibbed Lamy. Rori suggested that he try a finer nib, and I have medium, fine and extra fine nibs on my Lamys, and Day Timer pages, so I thought I would conduct an experiment!
When I tried to write with my beloved fountain pens in my new Day Timer diary at the start of this year, I also noticed the terrible bleed-through on the pages. This surprised me because in other ways the Day Timer paper seems generally better than other paper I have used in my Filofax. Even my Registrars' ink, which doesn't even bleed through on thin paper, bleeds through Day Timer!
So here's the test I did with my different nibs and different inks.
That's why I use biros in my agenda... I would love to use my fountain pens, but the paper just can't handle it! Filofax paper repels the ink, and Day Timer paper just sucks it in too much! I haven't tried other wet inks such as my V5s, but I might soon, although I'm quite happy with my 4-colour pens at the moment!
