Abstract: A square ink filter vessel for a printing press, like a rotogravure printing press, a flexographic printing press, or other like printing presses, includes a container having a substantially rectangular shaped cross-section with an open top, an outlet port on one side approximate the bottom of the container, a sloped bottom, where the sloped bottom being toward the outlet port, an inlet port on one side approximate the top of the container, and an internal ledge. A lid is adapted to close the open top of the container. A hinge couples the lid to the container, where the lid is hinged to the container on one side. A lid compression device is adapted to compress the lid to the container. A containment basket is adapted to fit inside the container, and has a plurality of holes on all sides and a lip adapted to rest on the internal ledge of the container.

Abstract: An improved ink system for a single pan design of a rotogravure printing press includes: the reservoir enclosing a substantial portion of the gravure cylinder; the intake section bottom having a slope at the bottom of the intake section; an intake port through the bottom of the intake section; an outtake port through the bottom of the outtake section; the outtake section bottom having a slope at the bottom of the outtake section sloping toward the outtake port; a dam release lever connected to the gate and extending outside of the reservoir, a plurality of channels through the vortex promoter; a pre-wipe bar located between the doctor blade and the vortex promoter; journal port seals located on each side of the gravure cylinder; and an angled doctor blade holder.

Abstract: An ink pan for a rotogravure printing press has a reservoir and a dam. The dam is located within the reservoir and divides the reservoir into an intake section and an outtake section. A gate is within the dam. The gate has an open position and a closed position. When the gate is closed the dam maintains an ink in the intake section until the ink exceeds a depth greater than the height of the dam, and then the ink flows over the dam into the outtake section. When the gate is in an open position the gate allows ink in the intake section to be emptied into the outtake section.
