A few examples of typefaces with more than nine weights: - Flama, by Mario Feliciano, has ten. - Ruse by Gerrit Noordzij has eleven. - TheSans by Luc[as] de Groot has sixteen, if one counts the eight hairline weights. - Taz, also by Lucas, has fifteen, if one counts the five hairline weights. All of the above folks are very prominent type designers, btw. Cheers, TReceived on Thursday, 18 June 2009 16:49:52 UTC
