PROBLEM TO BE SOLVED: To provide a slur gage enabling easy discrimination of an approximate amount and direction of doubling and free of difficulty in the discrimination according to the direction of doubling, in regard to the slur gage enabling discrimination of double printing which is a printing failure of an offset press. SOLUTION: When a combination of numerous parallel lines perpendicular to one another are made a gage part of one set, the slur gage is constituted of two sets or more gage parts different in inclination. The gage enables easy discrimination of doubling and the direction thereof, not depending on the direction of the doubling that occurs. |
