More Information
Summary:An inkjet ink for printing onto a print medium is provided. The inkjet ink evidences minimal tail breakup and improved drop trajectory, thereby evidencing improved print quality. The minimal tail breakup and improved drop trajectory are achieved by adding at least one surface active additive to the ink to provide the ink with a surface tension of at least 35 dyne/cm and a contact angle (with an orifice plate comprising KAPTON, an aromatic polyimide) of about 35 to 65 degrees.
