Abstract: For assessing the functioning of an ejection unit of an inkjet print head, a comparison of a residual pressure wave with a residual pressure wave reference is employed. To enable assessment during printing, multiple residual pressure wave references are provided, each relating to a condition relevant to the residual pressure wave. Such a condition may relate to an actuation status of an adjacent ejection unit which may cause crosstalk, for example. When performing the assessment, the condition during assessment is taken into account, for example for selecting a suitable residual pressure wave reference, such that an appropriate and correct assessment can be performed independent from the conditions during assessment.

Abstract: An inkjet print head includes an ejection unit having a liquid chamber for holding an amount of liquid, a electromechanical transducer operatively coupled to the liquid chamber for generating a pressure wave in the amount of liquid and a nozzle in fluid communication with the liquid chamber for enabling a droplet of the amount of liquid to be ejected through the nozzle. A method for detecting an operating state of the ejection unit includes the consecutive steps of actuating the electromechanical transducer to generate a pressure wave in the liquid; actuating the electromechanical transducer to suppress a residual pressure wave in the liquid; sensing an amplitude of the residual pressure wave in the liquid; and based on the result of the sensing step determining that the ejection unit is (i) in an operative state if the amplitude of the residual pressure wave is below a threshold or (ii) in a malfunctioning state if the amplitude of the residual pressure wave is above the threshold.

Abstract: A mounting structure for a plurality of print head units includes a frame; a rigid support mounted on the frame, the support having a plurality of mounting sites each of which is adapted to hold an individual print head unit; and an adjusting system for positional adjustment of the print head units relative to the frame. Each mounting site has at least one adjusting mechanism for individually adjusting, in at least one degree of freedom, a position of the print head unit that is held in that mounting site.

Abstract: A method for creating and processing specifications for a combined print product includes determining a plurality of parts needed to produce the combined print product, selecting a corresponding digital representation of the determined part from a digital representation collection, displaying the digital representations, and creating a digital hierarchical structure of the digital representations. An order in the digital hierarchical structure defines usage of the parts, appliance of the parts and a combination of the parts in a production process of the combined print product. Each part of the plurality of parts belongs to a part category out of a set of part categories, and the plurality of parts includes at least two resources, at least one device action, at least one finishing action, at least one combination action, at least one device and at least two logical concepts. A combined print product processing system is configured to apply the method.

Abstract: A method is disclosed for performing a user action to be applied on a digital item represented by a digital object displayable on a user interface touch screen of an electronic system. The electronic system is configured to apply the user action upon the digital item by means of an activation of a user operable element displayable on the user interface touch screen. The method includes displaying the digital object on the user interface touch screen, selecting the digital object, displaying a user operable element on the user interface touch screen, receiving an activation of the user operable element, executing the user action upon the digital item, showing an animation of a gesture to the digital object simultaneously with the execution of the user action upon the digital item, which gesture leads, when applied to the digital object, to execution of the user action upon the digital item.

Abstract: A method for transferring a sheet in a sheet transport assembly from a supplying conveyor to a receiving conveyor. The method includes arranging a contact side of a sheet in contact with a transport belt of the supplying conveyor, advancing the sheet on the transport belt in a transport direction along a process unit, which applies a process to a process side of the sheet opposite to the contact side, and to a transfer area where the sheet is transferred to a receiving conveyor. To correct for curl deformation of the sheet, air flow is directed onto the process side of sheet, which urges the sheet towards a supporting element. The air flow is controlled in response to a curl deformation behavior of the sheet.
