Web offset inks are specifically formulated for web offset printing processes, which are commonly used in high-volume printing, such as newspaper, magazine, and directory production. These inks are designed to meet the unique requirements of web offset presses, which operate at high speeds and often use continuous rolls of paper.

One of the key characteristics of web offset inks is their fluidity and low tack compared to sheetfed lithographic inks. This property allows the inks to transfer effectively from the printing plate to the substrate at high speeds without smearing or offsetting. Additionally, web offset inks are available with different drying capabilities, including those optimized for infrared, ultraviolet, or electron beam curing. This flexibility in drying options allows for efficient and rapid production.

Web offset inks contain water-repellent materials, which are essential for the offset lithography process, and the inks are tailored to adhere effectively to the varied substrates used in web offset printing, including uncoated and coated papers.
