摘要： An ink-based digital printing system for variable data lithographic printing includes an imaging member having a surface configured to absorb dampening fluid. A dampening fluid patterning system jets dampening fluid onto the imaging member surface according to image data to form a dampening fluid pattern. The system includes a transfer member that receives the jetted dampening fluid pattern from the imaging member at a dampening fluid loading nip for subsequent inking of the dampening fluid pattern to form an ink pattern. The ink pattern is transferred to a substrate from the transfer member at an ink pattern transfer nip.

摘要： An improved end-seal carrier assembly for supporting a seal in a seal-type continuous dampener. The seal is supported by a backing plate and pressed against the ends of the dampener's rollers. A carrier shaft is fixedly mounted to the backing plate. A shaft housing is mounted to the sideframe and has a hole extending longitudinally there through into which the shaft is mounted so to rotationally and longitudinally translate with respect to the sideframe. A coil spring is wound about a portion of the carrier shaft and has a first spring end operatively engaging the backing plate and a second spring end operatively engaging the shaft housing. The coil spring is configured to induce both a compressive and torsional bias between the backing plate and the sideframe. The shaft housing is rotatable for winding the coil spring and thereby establishing the torsional bias.

摘要： The improvements consist in supplying the wetting system with a water based solution including a determined additive. This solution is subjected, through a mechanism forming a part of this invention, to a process of agitation by which it adsorbs a high oxygen content. As a result of these improvements, the solution which wets the aluminium plate, from which the printing is done, acquires a high free oxygen content, increasing the water-ink interface and improving the quality of the printing.

摘要： To permit elimination of dampening rollers or an entire dampener in a lithographic, preferably offset printing machine, the printing form is formed as a cylindrical sleeve or jacket (3) fitted over a core (2), in which the cylindrical sleeve or jacket is formed with a plurality of interconnected pores (5), essentially uniformly distributed over the surface (4) and forming, within the sleeve or jacket, a connected pore fluid transfer network. Dampening fluid is then applied to the interior of the sleeve or jacket, for example from a chamber (6) between the cylindrical core (2) and the inner surface of the sleeve or jacket. The outer surface (4) can be imaged with oleophilic substances, for example by a thermal transfer process. To remove the images, for re-use of the printing form without removal from a printing machine, hot gases for example steam can be applied to the interior of the sleeve or jacket, so that the oleophilic substances at the outside will loosen for easy removal, or spall off.
