在《字体、排版简明入门（网页设计之字体在页面排版上的完全攻略）》一文中，我描述说：
“衬线设计的初衷是为了更清楚地标明笔触的末端，提高辨识率，提高阅读速度。”
事实上，Feitian在评论中指出
衬线设计的初衷是为了更清楚地标明笔触的末端，提高辨识率，提高阅读速度。——这句是错误的，衬线的产生是因为古代印刷技术的不完备，在字体的拐角处总是出现墨迹的渗出，为了解决这个问题而采用了衬线。
偶查看了维基百科：
The explanation proposed by Father Edward Catich in his 1968 book The Origin of the Serif is now broadly but not universally accepted: the Roman letter outlines were first painted onto stone, and the stone carvers followed the brush marks which flared at stroke ends and corners, creating serifs. The origin of the word “serif” is obscure, but apparently almost as recent as the type style.
所以，Feitian指出的是对的。
特此声明。
