A doctor blade, for removing excess ink from a gravure cylinder, comprises first and second blade sections formed of flexible metal. The blade sections are joined by a rigid, slotted coupling member so as to lie at a substantial angle to each other. The first blade section contacts an upwardly moving section of the cylinder at an angle of from 65 to 90 degrees. The second blade section is mounted in a cantilever manner to accommodate resilient deflection of the first blade section. The first blade section is thus maintained in substantially uniform pressure contact with the cylinder while at the same time being disposed at a relatively large angle to the surface of the cylinder for optimum doctoring effectiveness.
