A value-document printing machine includes, in the path of the printed material, at least a first printing site, at which first printing site a printing material passing through that first printing site can be printed, in segments, on at least a first of the two sides of that first printing material in a cycle at a print image width with a cycle length that is fixed in relation to the advancing of the printing material at the printing site, with print images of a print material length that is shorter than the cycle length. A second printing site follows next downstream that first printing site and through which the printing material passing through the printing site can likewise be printed with print images on at least a second of the sides of the printing material. A dryer device has a dryer which comprises a one- or a multi-part radiation assembly and which is arranged in the printing material path one of between the first and second printing sites and in the printing material path following the second printing site. Radiation can be supplied to the printing material passing through the dryer on the transport path of the printing material in order to dry the printing material. A control device that controls the drying unit of the dryer, with regard to activation and deactivation, is provided.

A dryer device for a printing press that prints in at least one printing position on a printing substrate by use of at least one printing unit, in particular a printing press for securities, includes a dryer with a drying unit formed by an array of a plurality of adjacent radiation sources. That array extends at least over the maximum width of the printing substrate and is used to supply radiation to the printing substrate in each activated state for drying the latter. A control device allows the radiation sources or some of the radiation sources to be switched on or off in a repeating cycle that comprises a sequence with at least one active and at least one inactive phase in correlation with one of a press and a printing-substrate phase position. The dryer device comprising the dryer and the control device is configured to switch on and switch off, for each cycle, only some of the radiation sources in some sections in at least four pre-definable radiation-source groups, spaced approximately equidistantly, i.e. at a distance deviating by a maximum 20% from the average distance and transversely to a transport direction, one of concurrently and collectively according to a sequence comprising one of multiple and at least three equidistant active phases of the same first lengths. The invention also relates to a printing press, in particular to a printing press for securities, comprising a dryer device of this type. During operation, the printing substrate is supplied with radiation in multiple tracks spaced apart transversely to the transport direction, synchronously with one of the printing substrate feed and with the press phase.

A print curing apparatus comprising a housing (1) for receiving a radiation source; a controller for controlling the power supplied to the radiation source (7, 7); a detector for detecting the type of radiation source (7, 7) and for feeding a signal to the controller in order to alter the power supplied accordingly.

A print target surface reforming device that makes it possible to obtain a higher reforming effect than in the prior art. A print target surface reforming device that reforms a print target surface and that is provided with: a conveyance section that is arranged more to the front than a printer on a printing line that automatically conveys a print target to the printer and performs printing, the conveyance section including on the upper surface thereof a conveyance path on which the print target is conveyed with the print target surface thereof facing upward; and a light source that is arranged so as to face the conveyance path and that emits light having a wavelength of 242 nm or less onto the print target surface of the print target that moves along the conveyance path.

Provided is an elongated housing which allows easy maintenance without being separated from the device body. The elongated housing, which is accommodated in a device body so that a lengthwise direction thereof becomes a first direction, includes a plurality of first rollers and a plurality of second rollers disposed on a first surface of the elongated housing to be arranged in a row along the first direction; and a plurality of third rollers and a plurality of fourth rollers disposed on a second surface of the elongated housing to be arranged in a row along the first direction, wherein the elongated housing is movably supported between a first state of being accommodated in the device body and a second state of being drawn from the device body in the first direction.

The invention relates to a non-stop printing processing system with a plurality of stations, comprising a first processing unit and second processing unit; each of the processing units comprises a set of film supply devices, a pressure roller, a stripped roller and a cured device; the pressure roller, the stripped roller and the cured device are mounted by a lift type; the system comprises an impression barrel, when a substrate is processed, the impression barrel is positioned under the substrate, a processed substrate is positioned between a processing unit processing the substrate and the impression barrel. The invention also relates to a non-stop printing process with a plurality of stations. The invention utilizes one or more film supply devices of a processing device to alternately supply a film to achieve the effect of automatic roll change and simulation positioning.

A light emitting diode (LED) module includes a first end cap, a second end cap and a reflector portion. The reflector portion extends longitudinally between the first end cap and the second end cap. The reflector portion includes a coolant passageway defined longitudinally through the reflector portion and is fluidically coupled to the first end cap and the second end cap. An LED package is disposed adjacent to the reflector portion. An orifice bushing can be disposed within a coolant passage defined in the first end cap to restrict coolant flow through the reflector portion to preclude starvation of coolant flow elsewhere in the LED module.

An ink curing apparatus comprising a lamp housing with a lamp fitting for a lamp terminal of a UV lamp at each opposing end, wherein at least one of the lamp fittings is non-conducting and has a non-conducting lamp terminal seat which has a concave profile for receiving a substantially spherical lamp terminal end piece; whereby, in use during the fitting or removal of a lamp, the at least one lamp fitting allows a lamp terminal end piece to rotate about multiple axes, while being retained substantially in position at the lamp fitting.

Examples include a printing unit having a forme cylinder, an impression cylinder, and a frame having two frame side walls located opposite one another. Two base modules each have respective base side walls that are an integral with the respective frame side walls. Each base module has four installation areas for rotational transport bodies, the relative positions of which coincide. Respective first two installation areas along a transport path form a selection group of each respective base module. The impression cylinder forms a printing nip with the forme cylinder. A rotational transport body is arranged in each installation area and a print head at a non-impact printing position is aligned with a rotational transport body arranged in an installation area of the first base module. Additionally, a print head of the non-impact printing position is aligned with a rotational transport body in an installation area of the second base module.
