Illinois Statutes Chapter 30. Finance § 500/45-15. Soybean oil-based ink and vegetable oil-based ink

(a) As used in this Section:

“Digital printing” means a printing method which includes, but is not limited to, the electrostatic process of transferring ink or toner to a substrate. This process may involve the use of photo imaging plates, photoreceptor drums, or belts which hold an electrostatic charge. “Digital printing” is also defined as a process of transferring ink through a print head directly to a substrate, as is done with ink-jet printers.

“Offset printing” means lithography, flexography, gravure, or letterpress. “Offset printing” involves the process of transferring ink through static or fixed image plates using an impact method of pressing ink into a substrate.

(b) Contracts requiring the procurement of offset printing services shall specify the use of soybean oil-based ink or vegetable oil-based ink unless a State purchasing officer determines that another type of ink is required to assure high quality and reasonable pricing of the printed product.

This Section does not apply to digital printing services.
