A printing unit includes a support frame that is supported to face a transfer passage for a sheet; an inkjet head that is fixed to the support frame and performs printing on a printing surface of the sheet; drive bodies that are rotatably supported on the support frame on both sides of the inkjet head in a width direction of the sheet and come into contact with the printing surface of the sheet; and a drive device that drives and rotates the drive bodies.

A printing station for use in a packaging material manufacturing system is provided. The printing station comprises a printing unit being configured to provide a print at a pre-set position on the packaging material, a detecting unit arranged downstream the printing unit and configured to determine the actual lateral distance between a reference position and the provided print, and a control unit being configured to store a desired lateral distance between the print and the reference position, and to adjust the pre-set position of a subsequent print based on a comparison between a desired lateral distance and the actual lateral distance.

A drying system and method of operating the drying system to dry a printed shrinkable web are disclosed. A web transport is adapted to convey the printed web between a heating apparatus and a cooling apparatus. The heating apparatus directs heat toward the web and the cooling apparatus concurrently chills the web. A temperature sensing device is adapted to develop an indication of a temperature of the web and the controller is adapted to adjust a temperature of at least one of the heating apparatus and the cooling apparatus in accordance with such indication.

In some examples, a printing press includes a support element with a circulatingly movable contact surface for contacting a printing substrate. An ink jet print head includes an ejection opening arranged to be directed at the support element. Additionally, the printing press includes a charging device that includes a charging electrode, which is arranged to be directed at the contact surface. The charging device further includes a counter-electrode, and the movable contact surface is at least partially arranged between the charging electrode and the counter-electrode of the charging device. A smallest distance between the charging electrode and the movable contact surface is greater than a smallest distance between the ejection opening of the ink jet print head and the contact surface. For example, the smallest distance between the charging electrode and the contact surface may be at least 50 mm.

An inkjet printer for forming, on a base, an image layer and an adhesive layer on which foil is to be formed includes a first head, a second head, and processing circuitry. The first head discharges an ink for the image layer. The second head discharges inks for the adhesive layer including a first ink and a second ink. The second ink has a lower wet spreadability than a wet spreadability of the first ink. The processing circuitry controls the second head to form an image area included in the adhesive layer with the second ink in a case where a width of the image area is less than a threshold, and form the image area with the first ink in a case where the width of the image area is not less than the threshold.

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.

Systems and methods in which dot-like portions of a material (e.g., a viscous material such as a solder paste) are printed or otherwise transferred onto an intermediate substrate at a first printing unit, the intermediate substrate having the dot-like portions of material printed thereon is transferred to a second printing unit, and the dot-like portions of material are transferred from the intermediate substrate to a final substrate at the second printing unit. Optionally, the first printing unit includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred in the individual dot-like portions from the donor substrate onto the intermediate substrate at the first printing unit. Each of the first and second printing units may employ a variety of printing or other transfer technologies. The system may also include material curing and imaging units to aid in the overall process.

A printing unit for use in a packaging material manufacturing system is provided. The printing unit comprises a plurality of printer rows, wherein each printer row comprises at least one printer head and a support roller for guiding the web of packaging material to be printed relative the associated at least one printer head. Said printing unit further comprises a support for the one or more support rollers and a lifting device connected to the support for moving the one or more support rollers relative the printer heads.
