Back in the old days when printing wasn’t common, people used to use some sort of wooden stamps (later they became rubber stamps) to print some commonly used graphics and text on paper. Many years later, people realized that by combining different commonly used stamps, it could be one of the easiest ways to mass reproduce the same information on paper. Without using the same stamps for printing the same glyphs on paper, distribution of information and knowledge would be much more expensive and time-consuming.
原型设计方式就像我们的活字印刷术，我们可以通过在木刻上的字，然后通过复杂的组合，快速的再生成同样信息。
