20080236411 | Printing Unit of a Printing Material Processing Machine and Method and Machine for Treating Printing Material - 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. | 10-02-2008 |
20080236732 | Method for the Production of a Steganographic Image on a Printing Material - A method for the production of a steganographic image on a printing material includes bringing the printing material into contact with a transfer film after an adhesive raster corresponding to the steganographic image was previously applied to the printing material and/or the transfer film. | 10-02-2008 |
20080272538 | Configuration for Detecting a Physical Parameter at a Stack of Sheets Lying on Top of One Another - A configuration for detecting a physical parameter at a stack of sheets resting on top of each other obtains signals from inside a stack in a wireless manner. At least one sensor that responds to changes in the parameter, is disposed between two sheets in the stack and is connected to a stationary evaluation unit. The sensor and the evaluation unit are connected by a wireless connection. | 11-06-2008 |
20090274298 | METHOD FOR PRODUCING A SECURITY FEATURE ON A FLAT SUBSTRATE - 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. | 11-05-2009 |
20100229741 | Method For Producing A Pseudo-Stochastic Master Surface, Master Surface, Method For Producing A Cylinder Cover, Cylinder Cover, Machine Processing Printing Material, Method For Producing Printed Products And Method For Microstamping Printing Products - 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. | 09-16-2010 |
20110111118 | PROCESS FOR THE SCREENED APPLICATION OF FLUIDS TO SUBSTRATES - A process for screened application of fluids to substrates includes i) providing a substrate being unscreened at least in a portion or a coating of the substrate unscreened at least in the portion, having a screened first image of a first fluid applied to the substrate in the portion, or ii) a substrate being screened at least in the portion or a coating of the substrate screened at least in the portion, having a first image of a first fluid with a different screen applied to the substrate in the portion (preferably with an offset printing form in i) and ii)). An unscreened second image of a second fluid (preferably transparent varnish) is applied to the substrate, covering the first image, in the portion (preferably with flexographic printing form). Formation of the second fluid on the substrate in the portion is substantially determined with the screen of the first image. | 05-12-2011 |
20110229628 | METHOD OF CREATING A STRUCTURED SURFACE IN THE FIELD OF THE PRINTING INDUSTRY - 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. | 09-22-2011 |
20120286808 | SYSTEM FOR LOCATING AND IDENTIFYING AT LEAST TWO SEPARATE ITEMS - 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. | 11-15-2012 |
20140061976 | METHOD AND APPARATUS FOR PRODUCING EMBOSSED STRUCTURES IN RADIATION-CURING MATERIALS - 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. | 03-06-2014 |
20140109782 | METHOD AND DEVICE FOR PRODUCING AND TRANSFERRING DIFFRACTIVE MICROSTRUCTURES TO A PRINTING MATERIAL AND PRINTING PRESS HAVING THE DEVICE - 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. | 04-24-2014 |
