A press assembly has a plurality of processing stations for the processing of sheets. These processing stations are arranged in sucession in a transport direction of the sheets for inline processing of the sheets. At least one of these processing stations is a non-impact printing unit and at least one processing station downstream of the non-impact printing unit is embodied as a dryer. At least one additional processing station is embodied as a coating unit. The coating unit is configured for applying a coating in a form of a varnish to each sheet. A plurality of individually controlled, non-impact printing units are arranged along the transport path of the sheets. Each of the plurality of non-impact printing units is configured as an ink jet printer.

In a first aspect, the invention concerns a method for providing a varnish coating to individual sheet substrates, said method comprising the steps of applying a liquid coating composition to the upper surface of a sheet substrate, conveying said sheet substrate along a track, while supporting the substrate from its rear surface, and subsequently curing and/or drying said coating composition. In particular, the aforementioned track is at least partly curved. In a second aspect, the invention relates to a device for performing such a method.

A drying device includes a plurality of blowers to blow air onto an object to be dried, the plurality of blowers being disposed along a direction of conveyance of the object to be dried, and a plurality of heaters to heat air inside the plurality of blowers. Each of the plurality of blowers includes an elongated nozzle arranged along a nozzle direction perpendicular to the direction of conveyance of the object to be dried, and an airflow generator to generate airflow to be blown from the elongated nozzle. The plurality of blowers includes a first blower including the airflow generator at a first end of the first blower in the nozzle direction and a second blower including the airflow generator at a second end of the second blower opposite the first end in the nozzle direction.

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.

A method and machine arrangement for sequential processing of sheet-like substrates are disclosed. At least one of a front side and a rear side of the substrates is processed in a production line one after another. A printing ink or another type of ink is applied in at least one non-impact printing device on the respective side of the substrates. The printing ink or the other type of ink is dried. A dispersion coating or a coating cured by UV radiation is then applied onto the respective side of the substrates. The dispersion coating or the coating cured by UV radiation is dried and the substrates are fed to a mechanical processing device for carrying out a further mechanical processing of the substrates. The further mechanical processing is performed by at least one of punching, inserting grooves, separating parts and by breaking out panels from their respective composite in the respective substrate.

A web printing apparatus includes a transfer device which transfers highly reactive ink/varnish onto a web, and a fixing device which fixes, on the web, the highly reactive ink/varnish transferred by the transfer device. The fixing device includes only a light irradiation device which irradiates the web with light in the wavelength range, in which no ozone is generated, to cure the highly reactive ink/varnish on the web without thermal drying of the web.

A liquid curing apparatus for a liquid transfer device includes a liquid transfer unit and a plurality of ultraviolet-emitting diodes. The liquid transfer unit transfers an ultraviolet curing liquid to a transfer target body. The plurality of ultraviolet-emitting diodes are arranged to oppose the transfer target body and emit only ultraviolet-wavelength light to irradiate the transfer target body to which the liquid has been transferred by the liquid transfer unit, thereby curing the transferred liquid.

The present invention discloses a four-position full-cell solar silicon wafer printer, including a base, an infeed guide rail, a detection camera assembly, a turntable assembly, a lifting module, a UVW correction alignment mechanism, and an outfeed guide rail. The UVW mechanism comprises two Y-axis modules, one X-axis module, a printing platform, a steel mesh frame, and a printing squeegee kit. The Y/X-axis modules are under the platform, their drive ends connected to the steel mesh frame. The squeegee kit moves left-right on the platform. It uses the Y/X-axis modules and detection camera to realize X, Y, three-axis motion, ensuring steel mesh-silicon wafer alignment and optimizing printing directions.
