A doctor blade (5, 7) for contact with an anilox roller (15) comprises a flat, elongate base element having a thickness of less than about 0.3 mm, which, along a longitudinal region of the doctor blade adapted for contact with said anilox roller, is provided with a coating (43). The coating comprises a metal matrix and at least about 65% by weight of one or more ceramic(s). The coating comprises 0 to 65% by weight of chromium carbide. An inking arrangement comprises an anilox roller and a doctor blade. A doctor blade is used in flexographic printing.

The present invention concerns an inking for a flexographic or a rotogravure press. The inking system uses a very small amount of ink coupled with an ink source made of two tanks with two different inks. Thanks to feedback given by measuring the output directly on the printed support, the system mixes the ink in the optimal proportions to ensure an optimal printing quality at any time. It can compensate any effect due to environmental changes like the humidity or the temperature. This system, coupled with a seven colours press allows for the replacement of spot colours in most cases thereby saving times and costs.

The invention discloses an inking system for a rotary printing machine, like a flexographic or rotogravure press. The inking system uses the nip area between two cylinders of the machine as the sole source for inking the printing cylinder. This results in an inking system with very little ink, thereby gaining in reaction time and ink waste.

Recess printing units are usable for printing on a substrate and using associated methods for operation. The recess printing units comprise an intaglio printing cylinder, which provides an image-forming pattern of recesses on its circumference; and an inking unit for applying ink to the pattern of recesses that are provided on the intaglio printing cylinder. The inking unit comprises a first inking unit cylinder which has, in a region of its lateral surface, recesses corresponding to the recesses in the intaglio printing cylinder and to which recesses ink can be supplied by an ink application device in the region of an application point lying on the circumference of the first inking unit cylinder. A second inking unit cylinder cooperates with the first inking unit cylinder and has, in a region of the lateral surface of the second inking unit cylinder, elevations corresponding to recesses in the intaglio printing cylinder or raised regions corresponding to regions of the image-forming pattern of recesses on the intaglio printing cylinder, which regions comprise recesses. The ink application device also comprises, on at least a downstream side of the application point, with respect to the operating direction of rotation of the inking unit cylinder comprising the recesses, a retaining device in the form of a doctor blade or an ink knife. The second inking unit cylinder comprises, on a lateral surface thereof, elevations corresponding to engraving on the intaglio printing cylinder.

A print agent application assembly cleaning tool is disclosed. The print agent application assembly cleaning tool may include a handle and a flexible blade. The flexible blade may be inserted into a gap between a pair of electrodes of a print agent application assembly. The blade may protrude from a distal end of the handle in a lengthwise direction. The blade may have a width that varies to define a curved profile. The width may reduce and subsequently increase along a length of the blade so as to define a recess in an edge of the blade.

A blade assembly of a waste catchment system for a roller having a support plate for attachment to a tray of the waste catchment system and a blade holder. The blade holder configured to receive a blade having a longitudinal axis and a free edge extending in the direction of the longitudinal axis and adapted to engage with the roller to be cleaned. The blade holder configured to receive and retain the blade, the blade being removably attachable to the blade holder. One of the blade holder and blades includes a channel and the other of the blade holder and blade includes a protrusion configured to be seated in and retained within the channel. There is a clearance fit between the channel and the protrusion.

A doctor blade, intended for a doctor blade chamber (6) for a flexography printing unit (1) equipped with a screened cylinder (4), presents in the form of a rectangular blade, with a functional longitudinal side (34) of which a longitudinal edge is capable of making contact with the screened cylinder (4), a longitudinal fastening side (33) and two lateral sides (36, 37).

The doctor blade comprises at least one opening located towards the functional longitudinal side (34) and towards the first of the two lateral sides (36, 37).
