A printing device for printing substrates, such as circuit boards, wafers, or solar cells, has at least one movably mounted printing unit with a working surface on which the substrate to be printed can be placed. The printing unit is paired with a transport belt device, which has a supply roller with a transport belt wound thereon, a collection roller for winding up the transport belt, and two deflecting surfaces, in particular deflecting rollers, which are paired with the working surface. The transport belt is guided by the supply roller over one deflecting surface and onto the working surface in order to form a contact surface for the substrates, and by the working surface over the other deflecting surface to the collection roller. The deflecting surfaces can be moved together with the respective printing unit. The supply and collection rollers are held on the printing device in a stationary manner.

A method of screen printing positionally synchronizes a plurality of pallet assemblies on a first screen printing machine with a plurality of pallet assemblies on a second screen printing machine. A screen printed garment having a properly aligned first image received from the first screen printing machine is transferred on a portion of one of the pallet assemblies on the first screen printing machine to one of the plurality of pallet assemblies on the second printing machine. The properly aligned first image on the garment is in proper positional alignment with a screen printing head on the second screen printing machine such that a second image complimentary to the first image is printed on the garment in proper position on the garment relative to the first image without user intervention to positionally locate the first image relative to the screen printing head on the second machine.

Various embodiments of a universal hold down pallet system for garment printing are described. In one example, a system includes a gasket plate comprising a plate having an opening and a gasket disposed at a perimeter of the opening, the opening sized and configured to mate with a pallet to hold a garment in place, and a head frame comprising at least one gasket plate guide channel positioned on a bottom surface of the head frame and a gasket plate latch assembly positioned at a first end section of the head frame, the at least one gasket plate guide configured to slidably receive the gasket plate. Where the gasket plate and the pallet are a set sized for a specified printing area, the set being one of a plurality of sets that are interchangeable in the universal hold down pallet system.

In some embodiments, a direct-to-garment personalization system for personalizing an article includes a direct-to-garment printer configured to print a graphic onto the article; a hanger for supporting the article; a storage area containing the article supported on the hanger; and a transfer system configured to remove the article from the hanger in the storage area and move the article to the direct-to-garment printer. The hanger includes a first arm coupled to a second arm, wherein the arms are collapsible to a smaller size in response to a pull force; and a hook coupled to at least one of the first and second arms.

Deflector units for use with a printing blade in printing a print medium through a printing screen, which are self-adjustable in a vertical direction for controlling production of rolls of print medium.

A screen printing device is disclosed for printing in a label area. An example screen printing device includes a printing pallet having a chest image printing surface connected to a label printing surface. The label printing surface extends outside of a chest image printing area of a printing machine when the screen printing pallet is loaded onto the printing machine. An example screen printing device includes an offset squeegee configured for a printing operation by the printing machine on the label printing surface.
