Microphotographic System for Ultra Long-Term Preservation Using Gold-Layer Photography

Abstract

Problems in preserving documents by analogue and digital systems are considered, and the gold-layer photographs that are capable of recording documents at a reduced scale are proposed for the solution to preserve documents compactly for a long-term. In the gold-layer photographs images are printed by using a gold layer onto ceramic bases, such as glass plates. As the image consists of chemically-stable substances, it cannot deteriorate easily, and the images can be preserved in a place without special preserving equipment. Moreover, since this has quite a high resolution, it can be reduced to such a small size.
