The tablet printing device developed by Otsuka Pharmaceutical Co. Ltd. was considered a revolutionary innovation because it made it possible to print clearly on uncoated tablets, including orally disintegrating tablets, which have been difficult to print on using conventional techniques.
The dramatic improvement in tablet identification made possible by this printing technology has satisfied a considerable unmet need of medical professionals and patients, and has contributed greatly to improved treatment adherence.
In 2001, the Japan Society of Pharmaceutical Machinery and Engineering established the Nakai Prize, which is named after Yoshinobu Nakai, the first chairperson of the JSPME, in order to honor the achievements of individuals or groups who have made considerable contributions to the development of pharmaceutical machinery technology.
The Nakai Prize is awarded for achievements in either software or hardware that are judged to contribute greatly to the development and advancement of pharmaceutical machinery technology.
