Japan firm prints needle eye-sized micro-book

A book with pages the size of the eye of a needle has been printed in Japan, with each tiny page showing a microscopic flower.

The 22-page micro-book, entitled Shiki no Kusabana (flowers of seasons), contains names and monochrome illustrations of Japanese flowers such as the cherry and the plum, it said, adding the 0.75 millimetre (0.03 inch) pages were impossible to read with the naked eye.

Toppan Printing said letters just 0.01mm wide were created using technology printers use to prevent forgery. It has been making micro books since 1964.
