Gravure Common Fault - Pattern Size Shift

1. When Printing, the longitudinal pattern shrinks.

Reason: Insufficient shrinkage margin. Due to the tension of the plastic film and heat drying during printing, the longitudinal dimension of the film is larger than the shrinkage of the printed image.

Countermeasures: The amount of shrinkage should be properly left when making plate, and the tension of the film should be minimized.

2. The length of the pattern in the longitudinal direction is elongated during printing.

Cause: The plate size has left too much of the shrinkage margin.

Countermeasures: Increase the film tension.
