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： In an image recording apparatus, edge sensors are disposed in front of and behind a recording position on a transport path of printing paper. The edge sensors detect a widthwise position of the printing paper in respective positions upstream and downstream of the recording position. A controller in the image recording apparatus calculates the widthwise position of the printing paper in the recording position, based on detection results from the edge sensors. Thus, the widthwise position of the printing paper in the recording position is identified without the placement of an edge sensor in the recording position on the transport path.

摘要： The measured winding diameter values Ds1(d) corresponding to the conveying distance d are measured by measuring the diameter of the printing medium M wound on the unwinding roll 71 by the diameter sensor 77. The measured winding diameter values Ds1(d) are smoothed by the low-pass filter to extract the smoothed winding diameter values Ds_avg1(d). By calculating the value of the diameter based on the initial diameter value Do1, the thickness value Tm and the conveying distance of the printing medium M, the calculated winding diameter values Dc1(d) are calculated. An operation of calculating the difference Ddiff1(d) between the calculated winding diameter value Dc1(d) and the smoothed winding diameter value Ds_avg1(d) while compensating for the delay by the low-pass filter is performed whereby the differences Ddiff1(d) are calculated. The calculated winding diameter value Dc1(d) are corrected by the differences Ddiff1(d).

摘要： A base material processing apparatus detects the amount of widthwise misregistration of a base material in each detection position (Po, and Pa to Pd) lying on a transport path, and then calculates a difference between a detection value in the reference position (Po) and a detection value in each of the remaining detection positions (Pa to Pd) as a meandering amount. Subsequently, the base material processing apparatus determines coefficients obtained when a variation with time in each meandering amount is applied to a predetermined model function, and thereafter calculates coefficients of the model function predicted as the meandering of the base material in each processing position (P1 to P4), based on the determined coefficients and a positional relationship between the reference position (Po), the remaining detection positions (Pa to Pd) and the processing positions (P1 to P4). This achieves the prediction of the meandering of the base material in the processing positions (P1 to P4) with accuracy without any detector disposed in the processing positions (P1 to P4).
