    摘要： In printing apparatus, an edge sensor detects a serpentine amount caused by transportation of a web. A predicted waveform data generating unit generates predicted waveform data on the serpentine amount to be produced in the following web in accordance with actually measured waveform data on the detected serpentine amount. A correcting unit corrects a printing position of an image in accordance with a shift amount, and applies a corrected printing position to a printing head. Here, the shift amount is determined with the shift amount determining unit in accordance with the predicted waveform data. Accordingly, the shift amount is determinable in accordance with the actually measured waveform data on the serpentine amount detected with the edge sensor more accurately than that through a method in which a shift amount is directly determined. This allows suppressed misregister.

    摘要： A base material processing apparatus includes a first edge sensor, a second edge sensor, and a displacement amount calculation part. The first edge sensor acquires a first detection result (R1) by detecting the position of an edge of a base material in the width direction at a first detection position. The second edge sensor acquires a second detection result (R2) by detecting the position of the edge of the base material in the width direction at a second detection position. The displacement amount calculation part calculates the amount of displacement in the position of the base material in the transport direction on the basis of the first detection result (R1) and the second detection result (R2). Accordingly, the amount of displacement in the position of the base material in the transport direction can be detected without depending on images such as register marks.
