OS401 ink is a black, general purpose MEK fluid that is directly compatible with Videojet’s 1000-series CIJ printers. An aftermarket alternative to Videojet’s V401-D, OS401 is ideal for high-speed marking on a variety of substrates, especially rigid plastics.

As a general purpose ink, OS401 offers excellent adhesion to a wide range of materials, including metal, plastic, glass, flexible packaging, and coated paper stock. Designed to create maximum code contrast, OS401 has a dry time of one or two seconds, helping users complete high-speed coding applications with reliable success.
