This new purple based color, Black Violet ink is anything but a basic purple color. Robert Oster Black Violet ink is a deep, dark color bordering on black. It has a dark purple hue in the color, thus the name. The combination of black and dark purple is fantastic. This color can be used as a unique everyday home or office color due to its dark nature and nice characteristics.

Robert Oster inks, although only carried by a handful of US retailers, continue to explode in popularity. This demand is due to the fantastic colors available and the inks characteristics such as sheening qualities, well behaving, etc.

During our review of Robert Oster Black Violet ink we found the following traits, which you may find useful:

Testing Factors

For this review we used a French made J. Herbin glass spiral dip pen on Rhodia dot pad paper. The dip pen has a tip that is equivalent to a fine fountain pen nib.

Bottle Sizes

Robert Oster Black Violet ink comes in one size, a 50 ml. plastic bottle. Each bottle comes with a ribbed black cap that we have yet to see a leak. Atop the cap is a white sticker indicating what color of ink is contained within the bottle as well as an actual ink sample.


Robert Oster Black Violet ink retails for $17.00 for the 50 ml. bottle. At this price point, it makes Robert Oster Black Violet ink a mid-ranged priced ink, which is not bad considering each bottle is hand crafted in Australia.

Dry Time

We experienced a 8-10 second dry time using Robert Oster Black Violet ink on Rhodia dot pad paper with a dip pen. This is not bad considering it contained high saturation qualities.

Bleed Through

During normal use, we experienced no bleeding while using Robert Oster Black Violet ink. However, during the cotton swab test, we noticed a very slight amount of bleeding at the most saturated point.


We experienced no feathering using Rhodia dot pad paper during normal use. During the water test, there was some feathering especially at the wettest points.

Water Test

Robert Oster Black Violet ink did not hold up really well during the wettest points of the water test, where we ran a wet cotton swab over a dried ink sample. However, after the swab became only damp, it held up reasonably well without a lot of line distortion or color smearing, etc.


Robert Oster inks in general usually have some very nice shading characteristics. Robert Oster Black Violet ink is no different, but may not have as much shading as some other ink colors. The dark black/purple predominately shows up, but with a lighter, dryer stroke, a beautiful purple will come out. This makes the shading, if you can achieve it, actually quite beautiful.

Saturation Test

Robert Oster Black Violet ink has medium to high saturation. During our saturation test, one dip of ink would produce an entire line across the paper without any loss of color or drying out.

Conclusion about the Robert Oster Black Violet Ink

Robert Oster Black Violet ink is a nice dark black purple ink, which dries reasonably well for being a medium to high saturated ink. The color is beautiful and the price reasonable. Since Robert Oster has so many colors to choose from, put Robert Oster Black Violet ink on your purple list to try when a true vibrant purple color is not in your mood. Perfect for everyday use at home or the office. Happy writing.

All these years of using ballpoint inks, I hated when black ink turned purple. But in fountain pens, it’s a thing of beauty. Thank you for the giveaway.

I enjoy the colors that are “black,” but not entirely pitch black 🙂

So far, I am loving the Robert Oster inks. It’s too difficult to pick just one as a favorite, though!

Okay, that is a wonderful color: purple, slightly stormy, but still dark enough to be easily legible and not too flamboyant for work use.

I’ve been really curious about this color; thank you for the review! This looks predominantly black, with purple undertones coming out when you don’t lay down too much ink. Very intriguing…. 🙂
Thank you for the opportunity to win this bottle of ink!

Robert Oster inks are among my favorites, and this ink is no different. I like to pair my pen and inks as much as I can, so this ink would go well in any of my pens which have black in them; I have no pens with purple. I can definitely see this as a daily ink.

Thanks for showing us another ink in the purple range. This one definitely is more on the black end.
