Abstract
An ink duct for use with a screen roller which comprises a working doctor blade and a closing doctor blade, wherein the working doctor blade has one or both sides partially or completely coated with an unreleasable coating of a low surface energy substance having a surface energy of 10 to 60 mN/m. This coating prevents disruptive ink deposits from forming on the side of the working doctor blade opposite to the ink retaining portion of the ink duct and reaching the doctored surface of the ink metering roller in an uncontrolled or random manner.
