Patent number: 8985020Abstract: A heating step is performed in a printing operation where a gas jet emitting from a nozzle assembly impinges the exterior surface of a printing plate. The gas impingement provides rapid and specific convective heat flux to the exterior surface of the printing plate.Type: GrantFiled: November 1, 2012Date of Patent: March 24, 2015Assignee: E I du Pont de Nemours and CompanyInventors: Carl Bernard Arnold, Gary W.

Patent number: 8985019Abstract: A method for making a flexographic printing master includes the steps of providing a flexographic printing support; applying image-wise on the flexographic printing support subsequent layers of radiation curable liquid by an inkjet printing device whereby one or more applied layers are immobilized using a curing device before one or more subsequent layers are applied, such that a relief with a top hat profile is obtained; and grinding the relief so that the height DT of a top hat segment is reduced. An imaging apparatus includes structure to perform the above method.Type: GrantFiled: December 1, 2009Date of Patent: March 24, 2015Assignee: Agfa Graphics NVInventors: Eddie Daems, Luc Vanmaele

Multi-layer, expandable sleeve for a printing press cylinder, particularly for flexographic printing
Patent number: 8960089Abstract: The invention relates to a multi-layer, expandable sleeve (100) for a printing press cylinder, particularly for flexographic printing. The sleeve has an inner layer (110) with a hard surface inner jacket (112), which defines a longitudinal axis (A) and the cavity for mounting on the cylinder, and an outer layer (130) with a cylindrical outer jacket (132) for carrying an outer shell, a printing plate or a separate outer sleeve, in particular. An intermediate layer (120), manufactured in the form of a lightweight honeycomb having honeycomb cells oriented radially (B) to the longitudinal axis (A), is provided between the inner jacket (112) and the outer jacket (132). According to the invention, the intermediate layer (120) comprises at least one honeycomb layer (122-1, 122-2, 122-3, 122-4, 122-5) consisting of shaped cured fiber composite honeycomb made of fiber material embedded in a resin matrix.Type: GrantFiled: September 22, 2011Date of Patent: February 24, 2015Assignee: Euro-Composites S.A.Inventors: Rolf-Mathias Alter, Patrick Freres, Oliver Bottler -
Publication number: 20150047522Abstract: Methods and devices for making a handheld stamp are provided. In one aspect, a stamp image is applied to a photosensitive and/or photo-reactive stamp surface that, when exposed to light having a particular wavelength for a particular amount of time, produces a handheld stamp. The photosensitive stamp surface may be a photosensitive foam, a photosensitive gel, and the like. In another embodiment, a rub-on transfer image is applied to a surface of a porous plastic sheet, where the applied rub-on transfer image prohibits the flow of ink through portions of the porous plastic sheet. In another embodiment, a transparency masks a portion of a photosensitive transfer material during light treatment to produce a stamp mask. The stamp mask is then applied to a porous plastic stamping material to produce a handheld stamp.Type: ApplicationFiled: August 12, 2014Publication date: February 19, 2015Inventors: Craig John Skinner, Luis Rodrigo Pineiro
