Ink Review: KWZ Gummiberry Ink

DSC_3620

I tested regular Gummiberry in a few pens: a Kaweco Sport eyedropper with a wet fine nib, a Waterman Laureat with a dry medium nib, and a Lamy Safari with both a dry extra-fine nib and a 1.1 mm stub. Unlike the iron gall version, regular Gummiberry looked different in different types of pen.

When I wrote with the Kaweco Sport and the wider Lamy stub, which deliver more ink on paper, regular Gummiberry was a medium shade of purple with good legibility and a friendly feeling.

In the dry pens I used, it had less verve and vigor, but more delicacy. I like the stronger look, but folks looking for a pastel purple like Pilot Iroshizuku Murasaki-shikibu might justifiably prefer Gummiberry in its lighter guise.

I thought it behaved very well. On low quality notebook paper, I saw very little showthrough or bleedthrough and no feathering. Even on what I like to think of as “The Worst Copy Paper in the World,” there was very little feathering. In fact, regular Gummiberry resisted feathering nearly as well the iron gall version. And I like the color on notebook paper — softer but legible.

Regular Gummiberry has much less water-resistance than the iron gall version. When a writing sample on lower-quality paper was splashed with water, traces of Gummiberry remained, possibly even enough to decipher the writing. But on smooth Rhodia even a few spatters of water nearly washed away the ink. The Rhodia water test is at the bottom of this photo.

Regular Gummiberry dried in a normal amount of time. On Clairefontaine and Rhodia, a line written with regular Gummiberry from the wet Kaweco Sport was completely dry within 25 seconds. On notebook paper with the Kaweco Sport, the ink was dry within 15 seconds. Dry time was less with the other pens.

Regular Gummiberry flowed very smoothly from all of the pens I used, even the two dry writers. I did not get much shading from the wetter pens, but I did see shading from the dry pens.

It cleaned out very easily from the Waterman and the Lamy Safari pens. That’s especially nice for a purple ink. I’m leaving Gummiberry a bit longer in one pen, just to evaluate that further.

The color feels like a standard purple, ala Waterman Purple, but leaning to the red side. Gummiberry doesn’t duplicate any of the purples I already own.

In the next day or two, I’ll compare the regular Gummiberry one-on-one with the iron gall version, and wrap up the Gummi’s.

  1. I think there wasn’t really one ink – as far as I know ink was shipped to the schools in powder or tablet form and mixed on-site. That was way back in the day, and it was just a medium purple AFAIK, so both would fit the bill. In my time it was offered more as a ‘legacy’ option, I guess, because by then the default was Erasablue. I tried to find some decent sources on purple ink to link to here but there isn’t a whole lot, and most of it is more like personal reminiscing – neat, but no wider context 🙂

  2. This reminds me a lot of the classic French school ink which is “violette” – a purple where the blue and red are balanced. The resemblance is strongest with the Kaweco Sport on the Rhodia paper.
