<ikiyo-e</i>, traditional Japanese woodblock prints, are probably the most numerous form of Asian pictorial art in the west, but their material characteristics and their reactions in treatment, exhibition and storage are little known to conservators. The author discusses the types of deterioration and damage they suffer, including the effects of light and moisture on vulnerable colorants. There are no established traditional methods for treating Japanese prints. The author presents an approach, discussing specific techniques of conservation treatment, which is a practical synthesis of traditional Japanese mounting methods, current western paper conservation techniques, and insights based on recent studies by conservation scientists. The paper concludes with a brief discussion of aspects of the exhibition and storage of Japanese prints. -- AATA
