PRINTING TEST METHOD AND PRINTING TESTER

摘要

The ink is dropped onto a flat plate, and then supplied to a printing area by a doctor blade. A pressure cylinder around which a material to be printed is wound is then rolled against the plate under a predetermined printing pressure, or the plate is moved to the pressure cylinder and rotated freely in a predetermined position by the frictional resistance thereof with respect to the plate. Thus, the ink on the printing area is transferred to the material to be printed to carry out printing. The rolling of the pressure cylinder or moving of the plate is performed by an air cylinder. The printing speed, the interruption of the movements of the pressure cylinder or plate, and the returning of the pressure cylinder or plate to its original position after the completion of the printing operation are controlled by regulating the pressure supplied to the air cylinder.
