Although the article itself refers to the substance as ink, it’s usually called coating(s).

Could it be called an ink coating? My understanding is that the distinction between ink and pigment is that ink is a solution while pigment is a suspension, can there be both kinds of coatings? or is it a meaningless distinction to draw in this context?

Sorry to barrage you with these questions if you don't know, but you brought up a pretty fine point so you seem knowledgeable about this :)

I'm no expert but in industry (and it may differ from company to company) coatings is mostly paints and inks are separate. Inks usually permeate (and add coloration to) a medium while coatings/paints bind and coat (to) a medium.

Anodized aluminum forms a porous surface that is dyed with ink to colour it, if I recall correctly.
