Japan Firm Prints Record-Setting Micro-Book

A book with pages the size of the eye of a needle has been printed in Japan, the publishing company said Wednesday, with each tiny page showing a microscopic flower. The publisher, Toppan Printing, also said the 0.75 millimeter (0.03 inch) pages were impossible to read with the naked eye.

The company, which prints everything from business cards to a laminated packaging material using biomass polyethylene film, has been making micro books since 1964.

Toppan said it would be applying to Guinness World Records to claim the title of world's smallest book, currently held by a 0.9 mm volume published in Russia.
