Abstract: A method for providing authenticity information has the following steps: a) providing a blank packaging (11) for a product to a printing machine (12), b) receiving or generating a template of the visual identifier (40) by the printing machine (12), c) applying, in particular printing, at least the visual identifier (40) on the packaging (11) by the printing machine (12), d) providing the packaging (11) having the visual identifier (40) to the quality control unit (14), e) receiving a packaging (11) for a product by a quality control unit (14), the packaging (11) having a visual identifier (40), f) reading the visual identifier (40) by the quality control unit (14), g) creating a first block (B), being a block of a blockchain, based on the visual identifier (40) by the quality control unit (14), the block comprising information about the visual identifier (40) and information about the packaging (11), and h) providing the first block (B) to the associated blockchain network (20) by the quality control unit

Abstract: In an example, a method includes receiving object model data at a processor, the object model data characterising an object to be generated using additive manufacturing. The method may further include receiving a status indicator for each of a plurality of additive manufacturing apparatus, the status indicator comprising, for each apparatus, an indication of an adaptable build volume. The processor may assign an object generation task corresponding to the received object model data to one of the plurality of additive manufacturing apparatus based on the status indicators.

Abstract: A roller arrangement for printing apparatus comprises a first roller. The first roller comprises a plurality of cells. Each of the plurality of cells receives an amount of a coating material. The roller arrangement further comprises an extractor to remove at least a portion of the coating material from a selected set of the plurality of the cells.

Abstract: An apparatus and method for use in generating a print job for an offset printing apparatus. The method comprising determining a print job to be printed on the offset printer comprises an odd number of separations, and in response to determining that the print job comprises an odd number of separations, alternating a print order of at least two separations between odd and even pages of the print job.

Abstract: Methods and devices for a lenticular image product include a print media, a printed faceted surface disposed on the print media, an interlaced image printed on the printed faceted surface, and a printed lenticular lens printed on the printed interlaced image and the printed faceted surface. The lenticular lens can be disposed over the print media selectively.

Abstract: Generating mixed ink composed of at least two basic inks with a mixing ratio in a liquid electrophotography printing press by: determining (30) a volume of one of the basic inks according to the mixing ratio; calculating (31) an interval for opening a leak valve (17) based on an ink flow in a basic ink connection tube; draining (32) the volume to the mixing ink tank (14) from the basic ink connection tube (12) via a leak tube by opening the leak valve for the calculated interval.
