This is my first real contribution to the site- please forgive any unintentional faux-pas!
A friend of mine wanted to see what Pilot Blue-Black (one of my favorite inks ever!) looks like on Tomoe River paper, so I write a thing up for her to check out in person using lyrics to one of her favorite songs.
Since I can't really figure out how to make file uploads here work just yet, I've linked to an imgur album of the pictures I took here: https://imgur.com/a/q4HSckJ
The pics were taken with my phone camera, with no editing done on them at all. The only light used was the evening sunlight from my window.
While the demonstration was intended merely to show off the appearance of the ink, I'll include my thoughts on its performance for you all:
I love this ink. It's nondescript enough to be used in a professional setting, but also quite exciting (just look at the shading, and the SHEEN that it has on Tomoe River paper!). It's easy to clean out of a pen, and is pretty darn water resistant (so much so that I use it to address envelopes to penpals, but it isn't directly advertised as waterproof of archival by any means). In terms of flow, I would define it as being wet, but not gushy. I haven't used it on a particularly broad nib as of yet, but it has behaved marvellously on all of the EF through M nibs that I've used it with. I haven't experienced any bleed or feathering with it on cheaper paper; as such it's become my daily-carry ink, along with my EDC pen, the Lamy CP1 (f nib).
