Claims20
A deflector unit for use with a printing blade in printing a print medium through a printing screen, the deflector unit comprising:
- a body which is disposable adjacent a respective one of the ends of a printing blade;
- a deflector which is movably disposed to the body for a range of travel along a first axis and acts to contain print medium within a lateral extent of the printing blade;
- and
- a biasing element which acts to bias the deflector from the body along the first axis;
- wherein the biasing element is wholly enclosed within the body throughout the range of travel of the deflector.
A deflector for use with a printing blade during a printing operation of printing a print medium through a printing screen to contain print medium within a lateral extent of the printing blade, wherein the deflector includes a deflector member, which has a first, engagement surface which engages a surface of the printing screen, a second, inwardly-facing surface which extends from the engagement surface and flares or tapers laterally outwardly in a first direction of printing, and a third, downwardly-facing surface which joins the second surface at a junction which is spaced at a distance from the first surface.
A deflector for use with a printing blade in printing a print medium through a printing screen to contain print medium within a lateral extent of the printing blade, wherein the deflector includes a deflector member which includes an elongate projection or recess, which is inclined substantially in parallel relation to the lateral edge of the printing blade and acts to reduce a pressure of the print medium at the junction of the deflector member and the printing blade in use.
