Ink Review #576: Diamine Robert

Today let’s take a look at Diamine Robert, from the “Iridescink” collection. I purchased my bottle of ink from Cult Pens.

The color:

Robert is a dark purple-magenta.

Swabs:

In large swabs you can see the bright green sheen.

Writing samples:

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

Feathering: None

Show through: High

Bleeding: Low

Other properties: no shading, monster sheen, and no shimmer. The sheen was visible in all nib sizes on all three papers.

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.

Comparison Swabs:

Robert is more vibrant than Bungubox Sweet Potato Purple, but not as vibrant as Pilot Iroshizuku Yama-budo. Click here to see the Diamine Inks together, and click here to see the purple inks together.

Longer Writing:

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.
