    摘要： A continuous seal type lithographic dampener is fitted with a one-piece metering roller which has a continuous surface coating of flame sprayed (as by plasma arc) chromium oxide particles providing a porous surface which is filled with a pore occluding sealer. The resulting cylindrical surface is than ground to a finish in the order of 20 to 30 micro inches. A finish coat of sealer is applied to the surface of the roller. The resultant metering roller is highly wear resistant and hydrophobic, having a surface energy in the order of 30 to 40 dynes/cm.

    摘要： The ink return circuit of a flexographic printing machine, for receiving ink from the ends of the gutter formed by a stereo transfer roller and a pressure regulating roller, comprises, at each end of the rollers, a vertical deflecting spout for receiving ink from the gutter, each spout having three doctor blades comprising a first blade extending substantially along the line of centers of the rollers and inclined to form an overflow and two lateral blades extending perpendicular to the first blade and to the end faces of the rollers. The spouts are biased against the end faces of the rollers and form part of a set of interchangeable spouts.

    摘要： A method of preventing an ink from increasing in viscosity is praticed by repeatedly performing the steps of supplying provided from an ink supply-aspiration nozzle to an ink reservoir provided between an inking roll and a squeeze roll pressed into contact with the inking roll, moving the nozzle toward one end of the reservoir and causing the nozzle to aspirate a predetermined amount of ink to produce a flow of ink in the reservoir toward the end thereof, and moving the nozzle toward the other end of the reservoir and similarly causing the nozzle to aspirate a predetermined amount of ink to thereby produce a flow of ink toward the other end. A diluting liquid is supplied to the reservoir while performing these steps.
