Figure 1
Microscope image of a line written from left to right illustrating the build-up of ink on the left side of the paper fibres (with black arrows indicating line direction and red arrows indicating some fibres with preferential ink build-up).
Figure 2
Graph showing examiner results in order of decreasing frequency of correct (unqualified) responses.
Figure 3
Graph showing proportional examiner results for Pen 1 versus Pen 2.
Figure 4
Graph showing proportional examiner results for line direction (left versus right).
Figure 5
Graph showing no significant effect of the line length (5mm versus 30mm).
