Abstract
Ensuring proper compass and register positioning during printing. Marks are imprinted on a carrying element and at least one sensor is present to detect the marks on the carrying element and a second sensor detects a seam on the carrying element. A control mechanism receives mark values from the first sensor and seam values from the second sensor, and discarding mark values when the seam is detected.
