A device (3000) for loading fluid into nozzle(s) of a nozzle-bearing body (3070) includes a first member (3010), having a first surface (3016), and a second member (3020) protruding from the first member (3010). The second member (3020) has second and third surfaces (3028, 3026), the second surface (3028) extending from the first surface (3016) at an angle. The first surface (3016) substantially complements the shape of the nozzle-bearing body's surface (3070). The device (3000) has a recess (3023) defined therein at least in part by the first and second surfaces (3016, 3028). When the device (3000) is placed into a working configuration with the nozzle-bearing body (3070), a tangent to the third surface (3026), in a region of the third surface (3026) proximate to where the second surface (3028) meets the third surface (3026), is substantially parallel to a tangent to the first surface (3016), in a region of the first surface (3016) where the first surface (3016) meets the second surface (3028), wherein, the recess (3023) forms a pocket for receiving the fluid.

A processing machine, in particular a printing machine, includes a unit having a storage container. The storage container comprises a roller and a base which delimit the storage chamber for a medium. One or more sliders are arranged along the edge of the base to form, together with the roller, an outlet gap for the medium. In the region of the one or more sliders, pneumatic means are provided to seal the supply chamber with respect to the medium. A method for operating such a processing machine is also disclosed.

A method of achieving precision registration in a roll to roll process by simultaneously depositing multiple inks onto a printing roll. One of these inks prints a pattern of fiducial marks onto a substrate while another ink prints a predetermined pattern on the same substrate such that the predetermined pattern bears a predictable spatial relationship to the pattern of fiducial marks. Consequently, even if the ink forming the predetermined pattern is invisible, or has such low contrast with the substrate that it is effectively invisible, or even has been dissolved away in a subsequent processing step, it is still possible to know where the predetermined pattern is by referring to the pattern of fiducial marks.
