Best Everyday Blue Inks: Monthly Ink Comparison

If you’re always on the look for the best everyday blue ink, you want to take a good look at today’s monthly ink comparison. In our monthly ink comparisons, we take a handful of inks, and put them side by side as they undergo standard ink review tests, writing samples, ink swatches, etc. Sometimes we feature a certain theme, other times we feature a new brand or new ink series release, but today is one of our monthly ink comparisons that features a group of similar inks. Read on to get a better look at some fountain pen inks often called the best everyday blue inks.

Ink Comparison Results: Before We Dive In!

Don’t forget – the “best” fountain pen ink choices always depend on a bunch of different factors:

  • the pen you’re using
  • the project you’re going to work on
  • your personal writing style
  • your own personal preferences

To help you figure out the best everyday blue inks for you…we ran a couple simple ink tests. For the dry test, we put down a writing sample, waited a specific amount of time and then ran a dry cotton swab over the writing to see if it was dry. We did this with varying “times” until we could determine how quickly the ink dried. You can see the results in the video. For the water test, we wrote out a writing sample, waited 1 minute, and then ran a wet cotton swab over the writing. You can see these results in the video as well. Hopefully this information will help you determine your own personal “best” everyday blue ink of the group.

Which Blue Ink Had the Most Shading & Sheen?

6 great everyday blue inks featured in today's side by side ink comparison.

When considering the 6 blue fountain pen inks in this ink comparison, we didn’t have any inks that had a heavy enough sheen to show up in normal writing, but when applied in a particularly heavy saturation level (like in the ink splashes or with a really broad nib), we had 4 blue inks that showed potential sheening traits: Diamine Asa Blue has the most powerful sheen followed by Monteverde Capri Blue and Pilot Iroshizuku Kon-Peki ink, and then Krishna ACR Free Range Blue surprised us with a very subtle sheen when we put it down with a Sailor Compass Hocoro dip pen using a 2.0mm nib.

FYI: When we talk about sheen, we’re referring to a visible metallic-like overlay that shows up after some fountain pen inks dry completely (often showing up in a completely different color than the base ink color). When we talk about shading, we’re referencing variations of the base ink color (lighter or darker colors) visible after the ink is dry.

While the Krishna Free Range Blue ink showed a pinky-violet sheen (very subtle), the other 3 sheening inks in today’s fountain pen ink comparison showed a maroon-ish/deep pink sheen at heavy saturation (you can see it in the ink swatches and in the name of the ink written beside the swatch for the Diamine Asa Blue ink).

NOTE: It was challenging to catch a good image of the sheen, but it’s easier to see in the video of the ink comparison. Check it out above!

Diamine’s sheen was the most extreme sometimes looking a bit hot pink, but outside of this ink comparison, the Diamine Asa Blue ink’s level of sheen would still just be a medium level. It’s not enough to be apparent in most writing and doesn’t disrupt it’s ability to fill your everyday ink needs.

The inks that showed the most shading possibilities during our ink comparison were Van Dieman’s Neptune ink and Rober Oster School Blue ink.

Which Everyday Blue Ink Was the Most Water Resistant?
