A method of forming a digital print on a surface by applying powder of dry ink including colourants on the surface, bonding a part of the dry ink powder to the surface by a digital heating print head such that the digital print is formed by the bonded dry ink colourants and removing non-bonded dry ink from the surface.

A method is provided for printing on hollow bodies in which the hollow bodies are printed on in a decorator having a rotating segment wheel. Printing ink provided by multiple different plate cylinders and inking units are each collected on printing blankets arranged one after another on the circumference of the segment wheel. The plate cylinders and inking units involved in the printing are arranged and set in such a way that, when printing on the hollow body, an iris print is, or at least can be implemented.

A printing device includes: a platen roller having a rotational shaft, a pair of bearings, and a holder. The bearings rotatably support end portions of the rotational shaft. Each of the bearings includes: a support portion, and an engaging portion. The support portion has an outer circumferential surface. The engaging portion is provided at the outer circumferential surface of the support portion. The holder includes a pair of fitting portions. The bearings are fitted into the fitting portions, respectively. Each of the fitting portions includes: a receiving portion configured to receive the support portion, an opening portion, and an engagement portion. The engaging portion is engaged with the engagement portion, whereby an expanding deformation of the opening portion can be restrained in a case where an external force directed in a direction toward the opening portion in the first direction is applied to the bearings.

A sheet-fed printing press has at least one coating assembly configured as a non-impact coating assembly. The sheet-fed printing press has at least one transport belt which extends, having at least one transport section of a circular path thereto, parallel to a transport direction along a partial region of a transport path provided for a sheet. At least one coating location of the at least one coating assembly is arranged along the transport section of the at least one transport belt. At least one printing head is arranged connected to at least one first frame of the at least one coating assembly. The at least one transport belt is arranged, connected to at least one second frame, via at least one deflection device and at least one radial bearing. The at least one first frame, apart from at least one installation surface which is different from the at least one first frame and the at least one second frame, is arranged in contact to the second frame at most via flexible connections.

A new method of combining pad printing with digital printing is presented, where the pad printer lays down a layer of ink and adhesive primer to accept the digital image. The pad printed surface is baked and a high-definition digital image is printed on top of the primer coat. The result is clear-coated and the coating treated with UV curing.

A machine arrangement, that sequentially processes sheet-type substrates, includes a plurality of different processing stations, one of which includes a non-impact printing device that prints the substrates. Further processing stations are a primer application device that primes the substrates and a dryer for drying the primer applied to the substrates. The primer application device and the dryer precede the non-impact printing device, in the direction of travel of the substrates. The processing station including the non-impact printing device, also includes a printing cylinder, on the circumference of which, the non-impact printing device that prints the substrates is arranged.

In order to provide a numbering and imprinting machine capable of minimizing the amount of wasted paper produced, the numbering and imprinting machine is provided with: a first-number inspection camera (124B) that is arranged downstream of the position of contact between an impression cylinder (112) and a first-number cylinder (113) of a first-number printing unit (111) in the direction of rotation of the impression cylinder (112), and images a first number printed on paper (W) held on the impression cylinder (112); a second number inspection camera (124C) that is arranged downstream of the position of contact between an impression cylinder (117) and a second-number cylinder (118) of a second-number printing unit (116) in the direction of rotation of the impression cylinder (117), and images a second number printed on paper (W) held on the impression cylinder (117); and a printing-press control device (10) that controls first- and second-number-cylinder throw-on and throw-off devices (38, 39) based on signals from the first- and second-number inspection cameras (124B, 124C) to cause the first-number cylinder (113) and the second-number cylinder (118) to make separating movements.

A printing technique is presented for efficiently printing (i.e. with production lines rates at high resolution and high accuracy) on outer surfaces of a plurality of objects passing in an optimized stream through a printing route/zone. According to this technique, at least one array of printing head units is provided being configured to define at least one printing route along a printing axis, where the at least one printing route is a substantially linear segment of a closed loop lane along which the objects are progressing.

A method of forming a digital print on a surface (2) by applying powder of dry ink (15) including colourants (7) on the surface, bonding a part of the dry ink (15) powder to the surface (2) by a digital heating print head (80) such that the digital print is formed by the bonded dry ink colourants (7) and removing non-bonded dry ink (15) from the surface (2).
