Adrian Frutiger and Hermann Zapf were required to second guess their original italics for Optima (Nova) and Frutiger (Next), under the (marketing?) premise/pretext of the superiority of “truth”, but it was immediately apparent this was a mistake. The truth will out, as they say.
I produced Brown (left) and Worldwide (centre) initially for newsprint, optically scaled. The minting sharpens up body type, and provides visual interest at display size. The third style is Beaufort, a glyphic effect which doesn’t require optical scaling, as the sharp serifs are close to asymptotic.
For some reason, rounding obtuse angled inside corners seemed more appropriate than negative thorns, perhaps because they don’t “decay” during process, and it expands the joint in a manner that balances the outside minting, which looks good when the font is closely inspected, rather than the typeset image.
