FLEXIBLE JACKET WITH INK MARKING ZONE IDENTIFICATION INDICATOR
20230174334 · 2023-06-08 ·

A removable flexible jacket for use in a printing press having a transfer cylinder for transferring a freshly printed substrate. The removable flexible jacket comprises a coated beaded sheet adhered to an plastic sheet, wherein a plurality of images are printed on a downwards facing side of the plastic sheet and visible through the upwards facing side of the coated beaded sheet, wherein the plurality of images provide indications of how to cut the sheet to size to fit different sized transfer cylinders and indications of zones of the flexible jacket to promote selective cleaning of the flexible jacket during use in transferring printed substrates.

Selectively lifting substrates

Example implementations relate to selectively deflecting substrates. One example implementation includes an apparatus to selectively lift a part of a substrate away from a transfer member when the substrate is advancing in a substrate coating system relative to the transfer member, such that, across a width of the substrate, a first part of the substrate is coated by the transfer member and a second part of the substrate, that is lifted by the apparatus, remains uncoated.

Apparatus for ink contaminant drying

An apparatus for ink contaminant drying includes a marker platen having a topside and a bottom side, and a plurality of heating elements located beneath the topside of the marker platen. The plurality of heating elements provides heating with respect to a surface of the marker platen, which prevents ink contaminants on the surface from remaining in a viscous fluidic state over a period of time.

To apply a fluid to a substrate

Apparatus to apply a fluid to a substrate, the apparatus includes a first roller to rotate about an axis and apply a fluid to a first side of the substrate. The first roller includes an outlet to provide gas to the substrate to guide the movement of the substrate subsequent to the application of fluid to the substrate.

METHOD FOR IMPROVING OPERATING CONDITIONS OF A PRINTING MACHINE, AND A PRINTING MACHINE

The printing machine comprises an impression cylinder (10) having a support surface (10a) supporting a web substrate (S), a pressure roller (12) pressing the web substrate (S) against the impression cylinder (10), one or more printing units (14) for printing ink on said web substrate (S) supported on the impression cylinder (10), and a liquid applying unit (18) for applying liquid insoluble with the ink being printed on the support surface (10a) of the impression cylinder (10) upstream of said pressure roller (12), said liquid forming a liquid layer (L) on at least one specific area of the support surface (10a) of the impression cylinder (10), so that the liquid layer (L) provides an ink-repellent coating on areas of the support surface (10a) not covered by the web substrate (S) and optionally an increased bonding of the web substrate (S) to the support surface (10a).

PRINTHEAD SERVICING

There is provided a maintenance apparatus to, while in a service zone, perform a cleaning operation of a set of printheads within a carriage. The maintenance apparatus comprises a cleaning structure and an actuation mechanism. The actuation mechanism is arranged to position the cleaning structure between an engaged configuration and a disengaged configuration. The disengaged configuration is activated by a first triggering element associated to the carriage interacting with the actuation mechanism subsequent to a cleaning operation. The engaged configuration is activated by a second triggering element as the carriage moves away from the service zone.
