Abstract
A multi-cylinder stencil duplicator includes ink-applying means in the form of a coating member offering a fixed nip between the coating member and a cylinder of the duplicator, ink being applied to one side of that nip and being held back as a wedge at the nip during rotation of the duplicator cylinder. The dispensing of ink to the wedge is controlled in response to variations in the capacitance between the coating member and the cylinder, so that when the ink wedge drops below a given threshold value further ink is dispensed.
