US Patent:

42145236, Jul 29, 1980

Filed:

Sep 27, 1978

Appl. No.:

5/946522

Inventors:

Saied A. Mabrouk - Macedonia OH
Edward T. Morgan - Mentor OH
James W. Davis - Bedford OH

International Classification:

B41F 724
B41L 2500
B41L 2700

US Classification:

101148

Abstract:

A lithographic ink and moisture control system is provided for maintaining copy quality over a wide range of operating and environmental conditions without special operator assistance. The control system, among other things, adjusts the ink and moisture feed rates to compensate for predicted changes in master conditions associated with the absorption of moisture by the master during the course of a copy run.

Appl. No.:

5/820760

Inventors:

Saied A. Mabrouk - Macedonia OH
Edward T. Morgan - Mentor OH

Assignee:

Addressograph-Multigraph Corporation - Los Angeles CA

International Classification:

B41F 724
B41L 2500

US Classification:

101141

Abstract:

A moisture control feed system of the bare-back type in which there is in nip-contact with a moisture transfer roll and the moisture transfer roll is driven solely by the shear resistance offered by the intervening layers at the nip of the ink and the moisture. The system includes an ink reservoir that simulates an oleophilic image in the form of a narrow strip extending transverse the direction of rotation of the master cylinder and is located outside the master retention area to supply ink to the oleophilic moisture form roll. The simulated image maintains the proper ink layer thickness on the oleophilic moisture form roll and the ink quality to assure proper rotational speed control of the transfer roll.

Assignee:

AM International, Inc. - Los Angeles CA

International Classification:

B41F 726
B41F 2502
B41F 2714

US Classification:

101148

Abstract:

A lithographic ink and moisture control system is provided for maintaining copy quality over a wide range of operating and environmental conditions without special operator assistance. The control system, among other things, adjusts the ink and moisture feed rates upon machine start up to compensate for moisture evaporated from the system during shutdown.

Appl. No.:

5/820823

AM International, Inc. - Los Angeles CA

International Classification:

B41L 2512
B41L 2714
B41F 726

US Classification:

101148

Abstract:

A lithographic ink and moisture control system as provided for maintaining copy quality over a wide range of operating and environmental conditions without special operator assistance. The control system, among other things, adjusts the ink and moisture feed rates to compensate for predicted high moisture conditions which occur at several short copy runs, wherein significant moisture is introduced with each new master.
