ColinK Posted July 10, 2022 Share Posted July 10, 2022 I am currently conducting a lightfastness test in my little studio, and I figured it might be of interest to this community. I am testing a variety of things, but I tried making it easy for strict fountain pen users to find what they're looking for by marking fountain pen inks with a * in the list bellow. The test is done on a piece of Life Bank Paper Writing Paper cut in half, taped inside a single-panel west-facing window, in front of a roofed-balcony in Canada. Not sure of the number of direct sunlight hours as I am never in a position to witness it myself, but there are at least a few! The control half of the sheet was concealed face-down in an opaque drawer, and I installed the other half in my window on June 8th. Here are the materials tested, and how they fared after a month of sun exposure : * = Fountain pen inks Green : Visibly unchanged. There might be a very slight difference, but it would be unrecognizable if you didn’t have a point of comparison to scrutinize. Yellow : Changed. Colour shifted and/or paled, but mark is still visible/readable. Red : Disappeared or almost. Readability is severely threatened.

I know now that many of Noodler's archival inks fade with time, at least the funky colours that tend to fade most in general. I have the sad confirmation that although they also use the term ''archival'' in their branding, Uni-ball is not a viable alternative for the aforementioned funky colours. YOTP is not a forever highlighter, but it sure fares better than most (who seem to weirdly turn brown). People have been debating whether Blue Ghost is a good way to leave behind fugitive inks a forever UV trace -- since it's already paled quite a bit, I would imagine it isn't. If any artist out there is stuck with a poorly-erasable color eno sketch under their black fade-resistant ink, I would suggest leaving it in a window for a month, as it will completely disappear! Shin-Ryoku is going very strong for an Iroshizuku ink. Lastly, Sharpie pens are also holding on much better than I thought, I wonder if it'll last. I'm a bit disappointed to see all of my non-waterproof black fountain pen inks fade and change colours. If anyone knows of a good black, lightfast water-soluble ink that I could use for washes, please let me know! I should check back in with new scans in a few months. Original scan; 1 month scan; 1 month UV pictures (control sheet is on the right) : Link to comment Share on other sites More sharing options...
