Robert Oster has two lines of ink: Signature and inkArt.ink. The former is readily available. The latter doesn’t appear to be available currently. I used the Signature ink for my comparison, but, for giggles, I included a chromatography strip of the inkArt.ink (IAI).
For those familiar with Organics Studio, you’ll know that at any given time, a certain ink may or may not be readily available. For that reason, I’m dubbing it “usually available.”
