A printing assembly has a frame having two side walls and has at least one cross member which extends at least in a transverse direction between the side walls and which has at least one supporting body which can be moved in relation to the frame in at least one parking direction and which extends at least in the transverse direction. At least one printing head is arranged on the supporting body and can be moved jointly with the supporting body. At least one first contact point, which is arranged on the supporting body, and at least one second contact point, which is arranged on the cross member, form a first contact-point pair. The first contact points lie opposite each other in the parking direction and are one of in contact and can be brought into contact with each other. At least one third contact point, which is arranged on the supporting body, and at least one fourth contact point, which is arranged on the cross member, form a second contact-point pair. The second contact points lie opposite each other at least at times at least also in a supporting direction orthogonal to the parking direction and orthogonal to the transverse direction and are one of in contact and can be brought into contact with each other.

A printing assembly has at least one frame, which frame has at least two side walls, between which two side walls a transport path, provided for the transport of printing material, at least partially extends. At least one transport direction is defined by the transport path provided for the transport of printing material. The printing assembly has at least two cross members which are spaced apart from each other in the transport direction and which each extend from one of the side walls to another of the side walls. Each of the at least two cross members has at least one first cross beam and at least one second cross beam spaced apart therefrom, which jointly bound at least one interior of the particular cross member at least partially in and against the transport direction. At least one component of one of a gas transport device and at least one additional device for supplying at least one printing head with one of energy and operating media and printing fluid and data and at least one gas and at least one inner device for one of cleaning and maintaining and covering at least one printing head is arranged in the at least one interior in each case. The printing assembly has at least one supporting body which can be moved, in relation to the frame, in at least one parking direction and which extends at least in a transverse direction between side walls. At least one printing head is arranged on the at least one supporting body and can be moved jointly with the at least one supporting body.

A printing apparatus includes a printing head; an airflow generating unit; a first flow path that includes a one-side end coupled to the airflow generating unit and an another-side end coupled to a first discharge port and through which the airflow passes; and a peeling unit configured to partially peel the label from the base sheet. When, the label partially peeled from the base sheet by the peeling unit, at least a portion of a peeled portion peeled from the base sheet is at a position not overlapping with the peeling unit in plan view and a non-peeled portion not peeled from the base sheet is in a state of overlapping with the peeling unit in plan view, the first discharge port is disposed at such a position that the airflow outputted from the first discharge port hits the back surface of the peeled portion.

A method of digitally printing a solder mask. The method includes providing a solder mask ink composition including: 1) a resin and 2) a solvent in an amount of at least 20% by weight relative to the total weight of the solder mask ink composition. The composition has a viscosity that is less than 1000 cps at a shear rate of 10 s.sup.1 and a temperature of 25 C. An aerosol stream is generated from the solder mask ink composition with a pneumatic atomizer using an atomization gas. The aerosol stream is directed through a nozzle and focused using a sheath gas onto a substrate while changing the position of the nozzle with respect to the substrate to selectively deposit a solder mask pattern. The solder mask pattern is cured.

The disclosure relates to a coating apparatus for applying a layer of particles to a receiving surface. The apparatus comprises a pressurized air source, an application chamber partially bounded by the receiving surface into which an air stream is delivered by the air source, an air return path for returning air from the application chamber to an intake of the air source to form an air circulation loop, a dosing device for introducing particles to be coated onto the receiving surface into the air circulation loop, and a controller serving to regulate the dosing device so as to maintain the particle concentration within predetermined limits. A method of applying a layer of particles is also provided, as well as printing systems benefiting from the present coating apparatus.
