INDIANAPOLIS — The state is changing the vendor it uses for the production of Indiana license plates, a decision that ends a long-time relationship in which state prison inmates were involved in the manufacturing of the plates.

The new $72 million contract with Intellectual Technology, Inc., will save the state approximately $14 million by not using prison labor over its five-year term, a spokesman with the Indiana Bureau of Motor Vehicles said on Monday.

The California-based company will facilitate the production and distribution of license plates, according to a contract signed and made effective earlier this month. ITI will also continue handling registration documents for the state, as it did under a previous contract.
