汉铸印尺寸基本为一公分见方,印面呈正方形,通常为四字平分印面,如下图:当然也有多字印,除白文印之外,也有朱文印以及朱白相间印。汉铸印形式规整,是讨论“知白守黑”的极佳案例。本文从布白和印文的关系入手,考察了印中点线面的存在方式,在对比了汉铸印和古玺的区别的基础上,对汉铸印布白作深入的讨论。汉铸印中的点在几何学中,点是二维上无限小的面积,是在时间上最简短的形,是一种复杂的(大小比例和形状),一种轮廓鲜明的外切体。[1]作为汉铸印中的点,和几何学中的点不同,有着一定的面积,比如一个直径1cm大 Han casting basic size of one centimeter square, printed square, square biscuit is usually the surface, as shown below: Of course, there are many characters printed, in addition to the white text printed, but also Zhu Wen Yin and Zhu white and white. Han cast form regularity, is an excellent example of This paper starts with the relationship between Cloth White and Indian, examines the existence of the mid-point line surface, and discusses the difference between Chinese and Indian ancient ink. In Geometry, the point in geometry is that the point is an infinitely small area in two dimensions, the shortest form in time, a complex (size and shape), a sharply outlined exoskeleton . [1] As a Chinese casting point, and the geometry of the point different, with a certain area, such as a large diameter of 1cm
