An apparatus for treating a relief precursor having a back side and a relief side. The apparatus includes a housing, a treating means for treating the relief precursor with at least one liquid, a removal means for removing debris and/or liquid from the relief precursor, the removal means arranged downstream of the treating means, and a conveying mechanism configured for transporting the relief precursor in a transport direction through the housing. The removal means includes a liquid removal and guidance body mounted for removing liquid from the back side of the relief precursor. The conveying mechanism is configured for pulling the relief precursor over and against said liquid removal and guidance body whilst the relief precursor is moved in the transport direction, such that in operation liquid is removed from the back side.

A flexographic printing plate includes at least one halftone printing area with a plurality of halftone dots. A halftone dot of said plurality of halftone dots is shaped as a relief area. Said relief area includes a central portion and a surrounding portion. Said central portion has a central dot floor with a first pattern of a plurality of pins protruding upwardly from the central dot floor. Said surrounding portion protrudes upwardly from the central dot floor and has a top side including a second pattern of a plurality of recesses. The first pattern and second pattern are such that the surrounding portion can be distinguished from the central portion.

The present invention relates to a water-based or solvent-based washing unit for washing a flexographic plate. The washing unit comprises a containment structure which defines a lower basin and at least two side basins which are supplied with the washing liquid and are arranged so that the water overflowing from the side basins is collected in the lower basin. A brush partially immersed in the liquid bath defined by the basin itself is installed at each basin.

Provided is a method for manufacturing a sleeve printing plate capable of forming an image pattern which applies printing on an object to be printed by laser engraving without generating cracks and chippings in a printing plate made of a photosensitive resin. The method for manufacturing a sleeve printing plate by making a printing plate made of a photosensitive resin surround an outer peripheral surface of a circular cylindrical sleeve body and forming an image pattern on the printing plate by laser engraving includes the steps of: washing and cooling the printing plate with water; applying heating treatment to the printing plate at a predetermined temperature; and applying heat radiation treatment to the printing plate after the heating treatment.

An anilox cleaning blanket. The anilox cleaning blanket may be installed on a plate cylinder of a printing system to clean an anilox roll. The blanket is made of a substrate. An adhesive layer is disposed on an upper surface of the substrate. A plurality of microfibers having a positive charge are adhered to the substrate by the adhesive layer. The microfibers engage with and clean the surface of the anilox roll.

Provided are a planographic printing plate precursor, a laminate thereof, and a method of producing a planographic printing plate precursor capable of satisfying all purposes for eliminating interleaving paper used for preventing scraping and peeling, preventing adhesion, imparting a plate-separating property for preventing multiple-plate feeding, and preventing scratches. The planographic printing plate precursor which includes a polymer layer on a surface of a belt-like support 12 includes a back coat layer 70 having an arithmetic average surface roughness Ra of 0.5 m or greater due to a surface roughness structure in which thin film portions 60 and thick film portions 62 are continuously formed on a rear surface of the belt-like support 12.

A flexographic printing plate includes at least one halftone printing area with a plurality of halftone dots. A halftone dot of said plurality of halftone dots is shaped as a relief area. Said relief area includes a central portion and a surrounding portion. Said central portion has a central dot floor with a first pattern of a plurality of pins protruding upwardly from the central dot floor. Said surrounding portion protrudes upwardly from the central dot floor and has a top side including a second pattern of a plurality of recesses. The first pattern and second pattern are such that the surrounding portion can be distinguished from the central portion.

The present disclosure relates to cleaning a surface in a printing device, wherein a steam guiding member directs a steam flow towards the surface; wherein the steam flow interacts with a substance on said surface to clean a portion of the surface.
