Angled printing

A printing machine 20 operative to print conductive medium onto a workpiece W1, W2, W3 in a printing operation by driving a print carriage in a printing direction across a stencil (40, Fig.5A) provided in the printing machine to force conductive medium on the stencil into at least one aperture provided in the stencil. The printing machine comprises a movable gantry 9, a drive configured to move the gantry in the printing direction, and a print carriage. The print carriage comprises a head unit 5 mounted to the gantry for movement therewith, and an elongate squeegee blade 6. The squeegee blade having a major axis 25 disposed along the length of the squeegee blade. The squeegee blade may be disposed in an inclined configuration in which the major axis of the squeegee blade is inclined to the printing direction P so as to subtend an angle α during the printing operation, where 0° < θ < 90°. The angle α may be created by rotating a workpiece with respect to the squeegee clade (Fig.3) or by inclining the squeegee blade with respect to the workpiece (Fig.5A).
