An ink metering roller for a keyless inking system which comprises a steel or aluminum roller core and an outer surface of highly wear-resistant hard particles imbedded in an oleophilic and hydrophobic bonding matrix, which matrix is subject to wear by contact with a coacting doctor blade, thereby creating gaps or interstices between the hard particles for conveying fixed amounts of input ink to the rotary press.
