Liquitex Professional Acrylic Ink, 5.1-oz (150ml) Jar, Carbon Black

My go-to ink for fine art projects. Fast-drying, color fast, that perfect black. Works both as a traditional ink and with paint.

I’ve been using these acrylic inks for a few weeks now, and they are incredible! The pigmentation is rich and vibrant—just a few drops go a long way. They flow beautifully on paper, canvas, and even over textured surfaces, making them perfect for everything from fine line work to bold washes.

Excellent ink composition. Very well saturated the pigments. Smooth even several minutes out in air. Fast dry on canvas... Excellent

Ordered for my son. Needed it to color some resin. He said it worked awesome. Amazing price and arrived quickly.

Works well. Flows, dark black, waterproof.

I was surprised by how thin and runny this ink is. For some reason I had in my mind that acrylic ink would be more viscous by comparison than something like India ink. That said, it seems to dry relatively quick and is impressively resistant to water. This is nice if you intend to apply washes or watercolor over your lines. In terms of darkness and saturation, this seems to dry somewhat lighter than expected, which also surprised me. I would probably refrain from using this in pens with refillable cartridges.

A wonderful acrylic ink. I use it with speedball pens for line work and also dilute it in waterbrushes to have a portable ink wash on the go. When diluted, it builds very easily to create lovely shades.Highly recommended!

I write with dip pens of various types and I usually like not so thick, not so thin acrylic ink. I previously used Speedball super pigmented acrylic ink, which was perfect except that ink needed a few drops of water added to adjust the viscosity and flow. Liquitex is billed as not requiring to add water, so I tried this brand this time, and I'm disappointed. The ink is too runny to be useful with dip pens, and the black color is not as dark as slightly diluted Speedball. The number of words I can write with a single dip is also about 1/2 to 2/3 of that of Speedball. Speedball ink is solid black, whereas this Liquitex looks more like dark gray. The ink feathers noticeably more than Speedball, too. For colors, I found Daler Rowney to be another thick ink with low feathering. Daler Rowney also requires a few drops of water added. If you are making large graphic art materials with brush and not with pens, on less absorbent coated paper, this brand might be still a good choice, but I'm going back to Speedball and Daler Rowney.Update July 2021I tried this Liquitex acrylic ink in a technical pen (Staedtler Mars Matic 700, line thickness=08) and this ink works well in the pen. It may still feather slightly at a thinner line width (not yet tested, but extrapolating from my experience with dip pens) but not noticeable at this broad 0.8mm line width. The ink flow is noticeably better than many other inks and it writes wet and reliably. This ink does not seem to clog the pen tip, at least this size.I came back to edit my review to add this observation, partly because many acrylic inks and drawing inks I tried seem to have large pigment particles or some dried up ink binder solids mixed in, and they tend to clog technical pens. This issue was never problematic with dip pens. (Tip: shake the ink bottle hours before filling the ink to mix the fine pigment particles, give enough time for the debris and big particles to sink, and take the supernatant with a syringe without disturbing the "sediment" to fill the pen.)I still think that Liquitex is less dark than most other inks but I'd take reliability over slightly lighter color.
