Abstract: A printed product is produced by providing a substrate, producing at least one interlayer on the substrate, printing a printed image onto the interlayer, and forming a barrier layer on the printed image. The barrier layer is provided on the printed image by applying a barrier composition to at least one carrier, at least partially drying the barrier layer and transferring it to the printed image. Preferred substrates have an acidic precoat layer as an interlayer. Such substrates can then be varnished with glossy varnishes, to achieve particularly high gloss values.

Abstract: A method for creating a printed product includes providing a printing substrate, providing a first fluid, applying the first fluid to the printing substrate as a first layer, providing an effect fluid as a second fluid, the effect fluid including a carrier fluid and platelet-shaped effect pigments, and applying the effect fluid to the printing substrate as a second layer, the second layer forming an effect layer. The first layer is created as a duct layer having a multiplicity of ducts. The ducts allow at least a portion of the carrier fluid of the effect fluid to pass through or enter, and the ducts substantially do not allow the effect pigments of the effect fluid to pass through or enter. This provides a cost-efficient and advantageous way of creating high-quality printed products with top quality finish and special effects having improved impact of the special effects.

Abstract: A method for operating a printing machine having a processor and a device for detecting features of printing substrates includes storing print jobs with the printing substrates appropriate thereto in a database. Features of at least one printing substrate are detected by using the device. The detected features of the at least one printing substrate are compared by the processor with the printing substrates of the print jobs from the database. The processor selects at least one print job in which the printing substrates of the print jobs from the database correspond to the at least one detected printing substrate or attain a predefined similarity. The at least one print job selected by the processor is subsequently executed on the printing machine.

Abstract: A method is provided for controlling the subsequent treatment of a workpiece that has previously been manufactured in an additive manufacturing process and has had marks formed thereon during the additive manufacturing process. The marks are used to control the application or ablation of material in the subsequent treatment of the workpiece.

Abstract: 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.

Abstract: A method for generating 3D objects includes providing a web of material, printing an image by inkjet printing in which the image corresponds to a section in a plane of the 3D object to be generated, applying a powder to the portion of the web of material that is provided with the image, cross-cutting the printed web of material into sheets, stacking the sheets on a stack of sheets, repeating the printing, powder application, cross-cutting and stacking steps, pressing the stack of sheets and exposing the object. 3D objects can be manufactured quickly, inexpensively and precisely with the method.

Abstract: For the production of embossed microstructures in radiation-curing materials, use is made of a micro embossing form fixed to a reflective or scattering cylinder surface. Via a press nip, the micro embossing form comes into contact with the substrate guided over a cylinder or a deflection roller. The radiation-curing material is acted on in one or both pockets, before or after the press nip, with radiation which penetrates into the press nip by reflection or scattering.

Abstract: A method and a device for producing and transferring diffractive microstructures to a printing material include applying a fluid to an embossing cylinder and there, during the rotation of the embossing cylinder, solidifying the fluid to such an extent that the fluid is transferred to a printing material in the manner of a film with a solidified microstructure. The embossing cylinder has a cover which is preferably constructed to be either soft as a “flexoshim” or hard as a “nickel shim.” A web-fed or sheet-fed rotary printing press having the device is also provided.

Abstract: A plate for creating holograms or other light-bending or diffractive microstructures on web-shaped or sheet-shaped printing substrates includes a relief for a relief printing process. The relief is formed of one or more raised dies and one or more adjacent depressions. A non-metallic microrelief for printing or embossing the microstructure is provided exclusively on the dies. The plate may be manufactured in a process in which a primary plate has a negative of the microrelief and the microrelief is created by molding the negative.

Abstract: A method for manufacturing a tool plate for treating a printing substrate includes pressing a master die having a surface structure and a tool plate blank coated with a cured layer against one another in a pressing nip, trapping a curable layer therebetween. As a consequence, the curable layer is applied to the cured layer of the blank and receives a negative of the surface structure in a molding process. The curable layer is subsequently cured. A printing machine tool plate and an embossing die for embossing holograms are also provided.

Abstract: A system for locating and identifying at least two separate items, for example packaging, includes a capacitive first sensor detecting a first measuring region at a first position of a sensor device, for example a sensor film on a shelf bottom for packaging, a capacitive second sensor detecting a second measuring region at a second position, differing from the first position, of the sensor device, an electrically conductive first mark of a first item in the measuring region of one sensor, an electrically conductive second mark of a second item in the measuring region of the other sensor, and an evaluation device evaluating signals from the sensors, the signals caused or changed by electrical conductivity of the marks. Items can be capacitively detected and information obtained can be used to improve warehousing. The sensors and the marks can be produced quickly and cost-effectively by printing processes or film transfer.

Abstract: A method for producing a pseudo-stochastic master surface for producing a cover or jacket of a cylinder for contacting printing material, includes providing the master surface with a pseudo-stochastic distribution of microsurfaces. The master surface is produced on the basis of a digital master in a jacket preliminary stage and serves for a preferably galvanic production of a microstructured cover, in which structure elevations correlate with the microsurfaces. The pseudo-stochastic distribution helps to avoid disruptive discernible effects, for example the moiré effect and helps to construct the microstructuring in a targeted manner. A master surface, a method for producing a cylinder cover, a cylinder cover, a machine for processing printing material, a method for producing printed products and a method for microstamping printed products, are also provided.

Abstract: A printing unit of a printing material processing machine, preferably a sheetfed offset printing press, includes a form cylinder and an impression cylinder. The form cylinder has a printing form for applying printed information to the printing material and the impression cylinder has a microstructured surface, preferably a cover, contacting the printing material. A surface of the impression cylinder contacting the printing material is provided with micro-embossed structures for applying embossed information to the printing material. The printing material is printed and embossed simultaneously. A security feature and/or a change in gloss can be implemented on the printed product through the use of the embossed, preferably micro-embossed, information.
