Offset ink

Source: Wikipedia, the free encyclopedia.

Offset ink is a specific type of

letterpress or lithography prints. Such ink must be specially formulated to resist other chemicals it will come in contact with on the printing press. It is widely used for printing high-quality images and text on various substrates such as paper, cardboard, and certain plastics.[1]

It is crucial that offset ink resist water-in-ink emulsification (e.g., repel rather than absorb water). It also should withstand degradation by the fountain solution that covers the non-printing areas of the engraved plate. Offset ink needs to be very rich in pigment so that its full color vibrancy is perceptible, even in minute quantity.[2][3]
