I have been testing the new adobe-Freetype CFF engine, and was wondering if the default 'darkness' of stem darkening is a little too high? How does the width of stems in a font effect the amount of darkness rendered? I think someone mentioned that thinner stems will render with relatively more darkness than thicker stems? Is that correct? Or is the amount of darkness a uniform value across all rendered fonts?
