De Atramentis, the Austrian ink company, has been releasing a growing line of fountain-pen friendly, waterproof inks for a while now. Buying them in North America, however, has been nearly impossible. Goulet Pens finally got them back in stock, I ordered, and within a couple hours people were reporting that they were out of them. Hopefully distribution will get worked out over time.
These inks are a wonderful addition to my arsenal and become the ones I use most often, I think. Not only are basic blue, black and brown available but they sell an equivalent of the CMYK (cyan/magenta/yellow/black) set that is used to generate color in offset printing. And they’re mixable. Jane Blundell has done a series of blog posts on mixing them.
I’ve just started doodling with them. I’ve mixed up a gray but otherwise I’ve been working with the colors straight out of the bottle. They are very similar to Platinum Carbon Black in use, though for some reason they feel smoother to me, maybe a bit wetter. So far I have them in Pilot Prera and Falcon pens and a Noodler’s Creaper. As is typical of the Creaper, there is a bit of start up problem but otherwise all these pens seem to like it. Time will tell.
