宋建本的字体在各类古籍版本概论的书籍中皆为简单的“宗柳”或“宗颜”之论。且不说各家说法不一,更是缺乏对字体演变的描述。然而古书字体不仅因地域有别,还会因时而变。福建地区因毗邻浙地,其刻书业的发展也仰赖于此,因而早期刻书与浙本相近而尚欧体,此后因刻书业逐渐成熟而自成一家,开始发展出建本自有的特色。而字体也随之发生转变,且各具特色。 Song Jianben’s fonts in all kinds of ancient books in the introduction of the book are all simple “Zongliu” or “Zong Yan” theory. Not to mention the different opinions of different parties, it is also a lack of description of the evolution of fonts. However, ancient books and fonts not only because of geographical differences, but also change from time to time. Because of its proximity to Zhejiang Province, the development of engraving industry in Fujian Province also relies on it. Therefore, the early engraving was similar to that of Zhejiang University but was still in European style. Since then, the engraving industry has become a mature one and started to develop its own characteristics. The fonts also change, and have their own characteristics.
