It took an MIT student and a laser, but it was done. So the new inks, dubbed "bad" are now laser proof, as well as bulletproof (waterproof, bleach/ammonia proof, archival)
It's also just a great, well behaved ink. The flow is excellent, the color is deeply saturated, there's very little shading, no sheen, very little feathering in a very wet F on the worst copy paper I have ever seen, almost no bleedthrough on said paper, and little to no showthrough. Dry times are instant on copy paper, average to quick on Rhodia.
Like almost all Noodlers inks, no sheen or special color effects on good paper.
The only downside (and this simply is unavoidable) is that on Rhodia, water will lift a little bit of the surface ink off, causing mild smearing, though the original lines where pen touched paper are still perfectly legible. On copy paper, almost nothing happens.
Are there snazzier blue-blacks with sheen and shading and all that jazz? Sure. But they won't outlast your grandchildren!
When you need a professional colored ink that stands out just enough on documents as to indicate an original signature without bleeding or feathering like mad on whatever paper it's on (provided you use an F or EF nib) this blue-black has you covered.
I've got an M nib coming in the mail so I can run the gamut of "everyday" nibs that you could use. The lamy EF-B are all quite wet, so look at the 1.1 for what a dry nib would look like.
