Type designers: Igino Marini will kern your fonts with his custom built application iKern. Other models using math to compute kerning values exist, (Illustrator and InDesign’s “Optical Spacing” feature is one), but I believe this is the first service offered to font makers — other than the feeble “autokern” built into Fontographer and FontLab — that claims to reliably appropriate kern pairs to a font. Without any customer testimonials, it’s unclear how effective iKern is, but Marini presents his own Fell Types as proof.
Update, April 21: I was inaccurate when I said iKern was the only app created to generate kerning. We overlooked DTL Kern Master, part of their Font Master software. Not much information online yet, but the technology on which it is based has been around for a while. More info in today’s comments below. Thanks Erik.
