Several lines of different intensity gathered into the bottom left corner of the print.
Using a scale, the varying pressure of drawing into a zinc plate with a steel needle was measured by collecting over a hundred data points.
On six sample spots, the depth of the lines as well as the hight of the burr were measured to determine avarage numbers of the relation between the force used for drawing and the intensity of the lines in the final print.
