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.

Abstract: A method for creating a structured surface or a safety or decorative feature based thereon in a process of the printing industry wherein a liquid, preferably ink or varnish, and particles, preferably pearlescent pigments or a material having a similar effect are applied to a substrate. The liquid is provided with a surface structure and is characterized by a creation of a random surface structure, in particular a structure of mountains and valleys, of the liquid and by the creation of a random particle distribution, preferably a random particle orientation, by blowing a gas such as air onto the unhardened liquid which may be heated if desired. The surface that is thus created has a unique structure that is discernible by the human eye or detectable by camera and may, for instance, have a light/dark change.

Abstract: A security feature is produced on a flat substrate, e.g. on paper or board. Particles—forming a cryptographic random pattern—are applied, preferably scattered on, to the substrate or incorporated into the substrate. Flexible pieces of wire or fiber, in particular thin pieces of copper wire, are applied to or incorporated into the substrate in a feature area corresponding to the security feature. The security feature can be provided with a protective layer, e.g. a laminate. A security feature produced in accordance with the invention can be detected simply and faultlessly and evaluated cryptographically. Furthermore, it cannot be imitated, or can be imitated only uneconomically, with known printing processes.

Abstract: In order to fit side doors precisely on a motor vehicle, this is performed mechanically by aligning an assembly frame on the side frame of the vehicle. This assembly frame has points for receiving supports in which the doors are held. These receiving points are configured such that they permit the alignment of the doors in directions X, Y and Z.

Abstract: A database evaluation system provides for intuitive end user analysis and exploration of large databases of information through real time fuzzy logic evaluation of utility preferences and nearest neighbor exploration. The system provides for domain modeling of various types of information domains using attribute mappings to database fields, and utility value weightings, allowing multiple different domain models to be coupled with a same database of information. User interaction with the evaluation system is through an interactive key generator interface providing immediate, iterative visual feedback as to which candidate items in database match the user's partial query. A proximity searcher user interface provides for nearest neighbor navigation and allows the user to determine which items in the database are closest to a given item along each independent attribute of the items, and selectively navigate through such nearest neighbors.
