Method and apparatus for testing the duplicating characteristics of pressure-sensitive duplicating sheets |
摘要 |
In a method and apparatus for testing the duplicating characteristics of pressure-sensitive duplicating sheets and duplicating sets produced therefrom, a stroke grid is drawn on the duplicating sheets to be tested by means of a marking stylus which is actuated either by mechanical or electromechanical devices to apply a selective a contact force, with the grid being evaluated either visually or by photoelectric reflectance measurement, the stroke grid consisting essentially of a plurality of individual strokes which overlap or are closely adjacent but which do not intersect.
