Abstract: A system that may include a apertured structure that is configured to support a substrate and a vacuum supply unit that is configured to (i) prevent a supply of vacuum to a first area of the substrate during a first processing period during which the first area is processed and a second area of the substrate is not processed; (ii) provide vacuum to the second area during the first processing period; (iii) prevent the supply of vacuum to the second area during a second processing period during which the second area is processed and the first area is not processed; and (iv) provide vacuum to the first area during the second processing period.

Abstract: A method for printing on a substrate, the method may include determining actual locations of substrate holes; printing a first ink on an object at locations that correspond to the actual locations of the substrate holes and curing the first ink to provide a holes mask; and wherein after the substrate is positioned on the object so that holes mask seals bottoms of the substrate holes then printing the second ink on the substrate thereby forming a predefined pattern on the substrate.

Abstract: An ink jet printer that includes a group of print heads; wherein the group of print heads comprises (a) a first sub-group of print heads that exhibit a first resolution; and (b) a second sub-group of print heads that exhibits a second resolution that differs from the first resolution; wherein in response to a printing scheme that associates a first area of a printed circuit board with the first resolution and associates a second area of the printed circuit board with the second resolution, the first sub-group is configured to print solder mask ink on the first area at the first resolution and the second sub-group is configured to print solder mask ink on the second area at the second resolution.

Abstract: Print arrangements are disclosed. An example printer includes a print head to apply an image to a substrate; a first roller and a second roller forming a first nip, the substrate to extend through the first nip as the substrate is being fed toward the print head; and a third roller and a fourth roller forming a second nip, first axes of the first and second rollers being non-parallel to second axes of the third and fourth rollers to enable a transverse force to be applied to the substrate prior to the substrate entering the first nip.

Abstract: A method for printing materials of multiple colors on an electrical circuit that comprises multiple regions of different functionalities, the method comprises: receiving or generating a printing scheme that defines a mapping between a functionality of a region and a color; and printing, by a printer module, according to the printing scheme and during a manufacturing process of the electrical circuit, at least some of the materials of the multiple colors on the multiple regions of the electrical circuit to provide an electrical circuit in which adjacent regions of different functionality are printed with materials of different colors of the multiple colors.

Abstract: Print arrangement, comprising a first roll, a transport surface, a nip between the first roll and the transport surface through which, at least during printing, a substrate is threaded, a drive system arranged to change a width of the nip, and a lateral stretch member arranged to engage a side of the substrate. The first roll comprises a two coaxially aligned roll segments of similar diameters for rolling over the substrate, with a distance in between.

Abstract: An intermediately fluid supply apparatus is to fluidically couple a primary fluid supply to one or more fluid-ejection printheads. A reservoir of the apparatus has a bottom surface and a number of side surfaces, and is open at the top of the reservoir. The reservoir is to store fluid supplied by the primary fluid supply, for ejection by the fluid-ejection printheads. A flexible membrane of the apparatus seals the top of the reservoir. The flexible membrane is to expand and contract over the reservoir in accordance with the volume of the fluid currently stored within the reservoir. A sensing mechanism of the apparatus is to directly or indirectly sense the volume of the fluid currently stored within the reservoir.
