A method produces a printed product. The method includes transferring a first Fluid onto at least one section of printing stock, applying a second fluid, having a dewetting effect on the first fluid, onto a form configured as a relief printing form or embossing form, and transferring the second fluid to at least some points of the section. In this manner printed products of high quality can be produced.

An image based correction system compensates for the image quality artifacts induced by thermal ghosting on evolving imaging member surfaces. With thermal ghosting directly tied to previous image content, a feed forward system determines thermal ghosting artifacts based on images previously rendered and generates an open loop gray-level correction to a current image that mitigates undesirable ghosting. For example, the correction system compensates for the thermal ghosting by making the current image lighter in areas that will be imaged onto warmer blanket regions, thereby cancelling out TRC differences between different temperature regions. A temperature sensor is used to measure the temperature of the imaging blanket due to the stresses induced by the image. This data is used to learn the parameters of the temperature model periodically during operation, and used in subsequent corrections to mitigate thermal ghosting in spite of changes in blanket properties over use and time.

A machine for drying inks of the UV type, the machine including a supporting frame, which forms at least one exposure chamber, which can be accessed from the outside and accommodates at least one UV ray emission source. On the supporting frame, there is at least one carriage which supports rotatably at least one pan for supporting at least one object to be processed which is provided, on its surface, with at least one print provided by UV inks. Elements are furthermore provided for the rotational actuation of the pan; the carriage is movable in order to move the pan from an exposure position to at least one respective access position, in which the pan is arranged outside of the exposure chamber, in order to allow the loading or unloading of the object on or from the pan.

An image forming system includes an image forming apparatus, a fixing device, a varnish image forming apparatus, an image reading portion, and a controller. The controller corrects first image data depending on first detection image data on a toner image formed on a first recording material and read by the image reading portion, and then depending on the corrected first image data, a toner image is formed on a second recording material subsequent to the first recording material. The controller corrects second image data depending on second detection image data on a varnish image read by the image reading portion, and then depending on the corrected second image data, a varnish image is formed on the second recording material.

An adjustable end cap for a high intensity LED light system includes an end cap body, a pivot base coupled to the end cap body and one or more adjustable fittings pivotally secured to the pivot base. Both coolant and electrical fittings can be provided. The end cap body defines passages therein that communicate with the coolant and electrical passages in the LED device. The coolant and electrical fittings can be pivoted transverse to the longitudinal axis of the LED device. Ninety degrees of pivot range for each fitting can be provided in one example.

A method is provided for configuring a drying device in a printing machine, in particular in a value document printing machine. The printing machine has at least one printing unit which comprises an imaging cylinder having a plurality of imaging printing elements or groups of imaging printing elements which are arranged in rows and columns on its circumference. A drying device has a dryer, by which print material, passing through the dryer, is subject to radiation. The drying device is configured for ongoing or upcoming production in such a way that the print material passing through the dryer, in order to be dried, is subjected to radiation in a plurality of tracks spaced from each other by non-irradiated tracks according to the same switch-on and switch-off sequence extending over cycle length. The configuration takes place with regard to one of a lateral position and a width of the tracks to be subject to two radiation by the dryer using product-related data or information regarding one of the number and the size and the position of value items to be printed next to each other on the print material portion and one of using data which comes from a device for image capture and an evaluation comprised by the printing machine or provided in parallel to such a device.

A high-intensity light source is formed by a micro array of a semiconductor light source such as a LEDs, laser diodes, or VCSEL placed densely on a liquid or gas cooled thermally conductive substrate. The semiconductor devices are typically attached by a joining process to electrically conductive patterns on the substrate, and driven by a microprocessor controlled power supply. An optic element is placed over the micro array to achieve improved directionality, intensity, and/or spectral purity of the output beam. The light module may be used for such processes as, for example, fluorescence, inspection and measurement, photopolymerzation, ionization, sterilization, debris removal, and other photochemical processes.

A curing chamber for curing and drying a flat printing product printed with at least one UV-curing pigment, comprising a first chamber wall including a cooling surface or is a cooling surface, a second chamber wall which is opposite the first chamber wall, wherein at least one UV lamp directed onto the cooling surface is arranged on or in the second chamber wall, third and fourth chamber walls which are arranged opposite one another between the first and the second chamber walls and which each comprise an introductory slot or removal slot and/or form an appropriate slot to the first chamber wall, fifth and sixth side walls arranged opposite one another and arranged between the first and the second chamber walls, wherein a gas inlet or a gas outlet is arranged in the vicinity of the third and fourth chamber walls, and the gas inlet is an inert gas inlet.

In certain examples described herein, a depositing mechanism performs an overcoat depositing operation. The depositing mechanism comprises a plurality of print head arrays. Each print head array is arrangeable in a deposit position to deposit an overcoat layer onto a substrate and a service position to enable servicing to be performed. In certain cases, an array controller causes at least one print head array of the plurality of print head arrays to be moved periodically from the deposit position to the service position according to a predefined servicing sequence during an ongoing overcoat depositing operation performed by the depositing mechanism.
