Today let’s take a look at Diamine Robert, from the “Iridescink” collection. I purchased my bottle of ink from Cult Pens.
Robert is a dark purple-magenta.
In large swabs you can see the bright green sheen.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 50 seconds
Water resistance: Low
Show through: High
On Staples 24 lb copy paper there was feathering and bleeding in most nib sizes, so it’s not an ink I would recommend for cheap paper. I did not see any sheen on this cheap paper.
I used a Pilot Vanishing Point Galaxy with a medium nib on Tomoe River paper. Similar to other monster sheening inks, the flow feels a bit sticky. When it was freshly inked it wrote great, but over the next few days it started to feel rather dry. I was not able to smear the ink after a few hours.
Overall, it’s nice to see a monster sheeny ink that isn’t blue or green. I would say it’s slightly well behaved, there isn’t any feathering or bleeding and doesn’t smear, but it does take a long time to dry and the flow is a bit dry.
