A device cures a UV-curable fluid, such as offset or inkjet printing ink, on a substrate by way of an emitter. The emitter includes at least two flash lamps which are disposed in a row. This provides a cost-efficient way of evenly and homogeneously curing UV-curable printing fluids at low environmental impact. There is also described a printing machine with a device for curing UV-curable printing ink.

A printed material includes a base material, an image layer, and an adhesive layer. The image layer includes an image of a first shape. The adhesive layer has a second shape. The image layer and the adhesive layer are on opposite sides of the base material.

An object of the present invention is to provide a method for producing printed material on which active energy ray-curable ink is printed, the method being capable of improving print density without impairing gradation expressivity.

The present invention is a method for producing printed material, the method including, in order: a transfer process of transferring ink to a transfer target surface of a substrate; and an impression process of bringing each of impression cylinders into contact with the transfer target surface to which the ink has been transferred, and at least one of the impression cylinders has a patterned impression part.

A system for printing documents and anti-forgery security papers especially banknotes is provided. The system includes a mechanical feeding mechanism, a hologram pattern print section, an invisible, fluorescence color and main colors pattern printing section using at least three units of ink jet, a varnish coating section, a rotating cylindrical silkscreen printing section for optical variable ink (OVI), a raised printing section, a delivery section, a paper and handle receiving section and a central computer control section. The system has been introduced to create various security features in securities wherein all of the processes including the raised printing are introduced in an all-in-on device.

A cylinder for conveying printed sheets along a UV or electron beam drier has inert-gas openings to which an inert gas is supplied at least temporarily during operation. A method for conveying printed sheets is also provided.

A flexographic printer is provided with: a printing plate for transferring ink at an ink transfer site to an object to be printed S; an anilox roll for supplying ink to the printing plate at an ink supply site; a plate cylinder on which the printing plate is wound and rotated; and an ink solvent supply unit for supplying a solvent for the ink on the surface of the printing plate in a post-ink transfer region that is downstream of the ink transfer site in the plate cylinder rotation direction and upstream of the ink supply site in the plate cylinder rotation direction.

There is described a printing press (100) comprising a printing group (2) adapted to apply on a substrate at least one ink or varnish vehicle containing magnetic or magnetisable flakes and at least one magnetic orientation unit (10) located downstream of the printing group (2) along a path of the substrate, which magnetic orientation unit (10) includes at least one magnetic-field-inducing device (12) adapted to orient the magnetic or magnetisable flakes contained in the ink or varnish vehicle applied on the substrate to induce an optically-variable effect in the ink or varnish vehicle. The printing press (100) further comprises a drying/curing unit (15) located along the path of the substrate and cooperating with the magnetic orientation unit (10), which drying/curing unit (15) is adapted to dry or cure the ink or varnish vehicle applied on the substrate following orientation of the magnetic or magnetisable flakes. The drying/curing unit (15) is mounted on a movable supporting structure (16) that is adapted to move the drying/curing unit (15) between a working position (WP), where the drying/curing unit (15) is cooperating with the magnetic orientation unit (10) and which is located proximate to the path of the substrate next to the magnetic orientation unit (10), and a retracted position (RP), where the drying/curing unit (15) is retracted away from the magnetic orientation unit (10) and from the path of the substrate.

Provided is a heat radiating apparatus for radiating heat of a heat source in air. The heat radiating apparatus includes a support member in close contact with the heat source on a first principal surface side, a heat pipe supported by the support member, and a plurality of heat radiating fins in a space that faces a second principal surface to radiate the heat transferred by the heat pipe. The heat pipe has a first line part thermally joined with the support member, a second line part thermally joined with the heat radiating fins, and a connecting part. A plurality of heat radiating apparatuses can be connected such that the first principal surfaces are successive, and each of the plurality of heat radiating apparatuses has a receiving part for receiving the connecting parts of adjacent heat radiating apparatuses in the space that faces the second principal surface.
