The present invention presents a solder printing apparatus comprising a clamping mechanism (100), and a position adjusting mechanism. The clamping mechanism (100) comprises a mounting base (130), a lead screw (142), one or more clamp base (110), and one or more adjustable height stopper (120) for locating and clamping. The position adjusting mechanism comprises an adjustment for X direction positioning (150), an adjustment for Y direction positioning (160), an adjustment for Z direction positioning (170), and an adjustment for rotation position about the Z axis (180), each having a turn knob with a micrometer scale, as well as, a position indicator (152, 162, 172).

A flexographic printer is provided with: a printing plate for transferring ink at an ink transfer site to an object to be printed S; an anilox roll for supplying ink to the printing plate at an ink supply site; a plate cylinder on which the printing plate is wound and rotated; and an ink solvent supply unit for supplying a solvent for the ink on the surface of the printing plate in a post-ink transfer region that is downstream of the ink transfer site in the plate cylinder rotation direction and upstream of the ink supply site in the plate cylinder rotation direction.

A fluid distribution device, for applying a fluid onto a transfer roller, comprises includes an elongated chamber, at least one inlet for letting a fluid into the chamber, a longitudinal opening extending in the axial direction and adapted to face a transfer roller to allow fluid to exit the chamber and contact the transfer roller, and at least one wiper blade extending along at least a portion of the longitudinal opening. The chamber includes, at each of the two axial ends of the chamber, a wall separating the chamber from a cavity. The wall has a wall surface arranged to face the transfer roller when the device is in use. The wall is dimensioned so that the wall surface will be distanced from the transfer roller when the device is in use, so as to allow fluid to be present in a gap between the wall surface and the transfer roller.

A doctor blade (5, 7) for contact with an anilox roller (15) comprises a flat, elongate base element having a thickness of less than about 0.3 mm, which, along a longitudinal region of the doctor blade adapted for contact with said anilox roller, is provided with a coating (43). The coating comprises a metal matrix and at least about 65% by weight of one or more ceramic(s). The coating comprises 0 to 65% by weight of chromium carbide. An inking arrangement comprises an anilox roller and a doctor blade. A doctor blade is used in flexographic printing.

Certain examples of seals that can move along a slit are disclosed. The seals can comprise a first leaf, a second leaf, and a biasing member to push the first leaf away from the second leaf. Also, apparatus for applying a fluid, and printing systems are described.

An inking system for a printing press is provided, including a structural member; an internal ink manifold housed in the structural member; a shuttle inside the internal ink manifold and movable along a length of the internal ink manifold; and a plurality of ink supply sources, a first ink supply source for connection to a first end of the internal ink manifold and a second ink supply source for connection to a second end of the internal ink manifold.
