Tono & Lims - Star Light Series: Antares
Another good and very usable fluorescent ink! It’s sort of a dark magenta or fuchsia color depending on the paper. On Iroful it’s lighter, on Midori and Col-o-ring it’s darker.
The glow under UV light is mostly the same color, but brighter.
Scans
Scans are true to color and the writing is very even and well-behaved on all three paper types.
Photos
These photos show each swatch under visible light, a mix of visible and UV light, and UV light alone.
Col-o-ring paper is very reactive to UV and the paper itself glows blue brightly, which makes the glow of the ink appear less intense. Iroful is mildly reactive to UV and glows a little. MD reacts very low so it shows off the glow of the ink the best.
A mix of UV and visible light seems to yield the best results to the eye.
It glows brightly, and each paper brings it out differently. On Iroful the glow is more red, col-o-ring is more purple, and Midori is more pink. The text glows especially brightly on Midori, as expected.
Microscope
As with the scans and photos there are subtle color differences between the papers.
Microscope UV
These photos show magnified portions of each swatch under visible light, a mix of visible and UV light, and UV light alone.
Microscope UV photos are a bit tricky since I have to dial the light up/down on the microscope and add UV light from a flashlight. As the UV light intensifies, it seems to play tricks with the microscope’s camera with the background to some extent.
Nothing too surprising here, but it looks neat!
Chromatography

Chromatography has a little gray at the start and then fades into magenta near the end.

As with some other fluorescent inks, the empty area in the middle glows significantly, but this one also has an added band of red glow after that, followed by a very thin blue halo of glow past the leading edge.
Group Photos
Shows a good direct comparison for the UV reaction of different papers.
Bonus Microscope/UV Photos
These were leftovers that didn’t fit into the grid above, but were still worth sharing.
Verdict
It’s not a color I typically would have chosen had it not been fluorescent, but I do like it after using it more. I keep it inked in a TWSBI and I’ve used it regularly.
