Gull

To tear the point holes in a sheet of paper while printing. This is generally caused by the end of the spvir being turned, and may be remedied by filing it to a tapering point. At times a gull is caused by the points not falling fairly in the centre of the groove. The paper being too wet sometimes causes the point-holes to tear; and the frisket being raised sharply in heavy jobs, or when the forme has a tendency to “lug,” has the same effect.
