METHOD AND DEVICE FOR AUTOMATICALLY POSITIONING MEASURING REGION OF PRINTING CHECK STRIP FOR AUTOMATIC INK CONCENTRATION MEASURING DEVICE

摘要

PURPOSE: To locate a measuring area automatically even for an incomplete check strip by engaging an original print plate with a rail having an alignment mark and controlling a measuring head movable in X, Y directions through a controller. CONSTITUTION: An original print plate 6 is set on a rail 5 laid on a test table 11 such that the first measuring area 8 of a print check strip 7 comes above a mark 9 on the rail 5. A measuring head 1 moves in the X direction 3. The head 1 is stopped at the position of the marking 9 by a distance detector 2 and then moved in the Y direction to pass through a first measuring are 8. The measuring area 8 is recognized by a measurement signal received by the head 1. After the head 1 is moved entirely over the measuring area 8, Y position of the measuring area is stored. For subsequent movement of the measuring head 1, the check strip 7 is approached at the stored Y position. These sequences are controlled by a microcomputer 10.
