Offset print apparatus and methods

Offset print apparatus comprising a blanket arranged in a closed loop around a plurality of rollers, each of the plurality of rollers being rotatable about a respective roller axis to support and convey the blanket around the closed loop,

• wherein the plurality of rollers comprises:
• a primary steering roller rotatable about a primary roller axis and being pivotable about a primary steering axis perpendicular to the primary roller axis, the primary steering axis being inclined by no more than 45° relative to a plane tangent to a portion of the primary steering roller wrapped by the blanket such that pivoting the primary steering roller is configured to introduce twist to the blanket;
• and
• a secondary steering roller rotatable about a secondary roller axis and being pivotable about a secondary steering axis perpendicular to the secondary roller axis, the secondary steering axis being perpendicular or inclined by more than 45° relative to any plane tangent to a portion of the secondary steering roller wrapped by the blanket such that the secondary steering roller is configured to introduce stretch to the blanket;
• wherein the primary and secondary steering rollers are each independently pivotable and the offset print apparatus further comprises an actuator to actuate pivoting of the primary steering roller and the secondary steering roller.
