The drawing equivalent of sharpening.

I noticed the cover image of the Sept 15 New Yorker had an illustration technique that seemed quite close to the PPing sharpening.
Note the dark and light lines that emphasize the border between tones.
Anyone know  the name for this illustration technique?

That is pretty close to the "ligne claire" style exemplified by Hergé in Tintin, isn't it?

Looks like it, although I couldn't see any examples where Herge uses white lines on the border of dark areas as I found here, but really really close.

Panasonic uses light gray line to make the border of the frame on the LCD clear which is an excellent idea and works marvelously.
