本研究的目的是对近代以来的古籍、木刻彩印、档案进行材料质量和特征的科学分类。本研究对利用显微镜的测量设备（CCD扩展图）测量纸张质量的技术进行了研究。这次调查最大限度地减少了对历史遗产的影响，明确了纸的特殊性。首先，以“手工日本纸”为样本进行了各种科学研究。对旧版印刷图书、木刻彩印、档案进行调查，主要从以下内容展开。(1)以旧印刷书籍为例，调查了江户出版的各个时代的书籍的纸张质量。(2)木刻彩印则在1765年（后来的梅花年）出现了多种颜色。耐用的“手工日本纸”（housho），以kozo为原料。对木刻彩色印刷用纸的质量进行了研究。（三）档案的，在一种原料上，附以该古藏为原料的颜色、用途、生产地点和名称，如纸（弹石、家居等）等。对纸张的各种质量进行了分析。报告总结了一项调查的结果。调查结果是用个人电脑处理的。

The purpose of this research is to perform scientific classification for the quality of the material and characteristics clearly for the old printed books, woodcut color print, archives from modern times.This research did research on the technology which measures quality of paper with the measurement equipment (CCD expansion picture) which used the microscope. This investigation minimized the influence on historical heritage, and clarified the special feature of paper.First, various kinds of scientific research was performed by using "Handmade Japanese paper" as a sample.Investigation to old printed books, woodcut color print, archives was conducted from the following contents.(1) In the case of old printed books, the quality of paper of the book published by Edo for every age was investigated.(2) In the case of woodcut color print, it becomes many colors in 1765 (afterwards Meiwa year). Durable "Handmade Japanese paper" (housho) which used the kozo as the raw material. The quality of paper used for woodcut color print was investigated.(3) In the case of archives, it is at a raw material, and a color, a use and a place of production, and names, such as paper(danshi and housho etc.) which used the kozo as the raw material, are attached.Each quality of paper was analyzed. Results of an investigation were summarized in the report.Results of an investigation were processed with the personal computer.
