Soy-based Inks Inks made from soybeans, unlike traditional ones which are petroleum-based. Soy-based inks are more environmentally friendly, might provide more accurate colors, and make it easier to recycle paper. However, they are slower to dry than other inks.
Soy-based inks were developed in the late seventies and early eighties as an alternative to petroleum based ones due to the increasing prices of oil. Nowadays about one quarter of commercial printers in the United States use soy ink. |
