ABSTRACT:
According to aspects illustrated herein, a method, a system, and a printmaking device for performing closed loop lateral and skew control of a sheet is provided. The printmaking device includes a feed path, printing module, and sheet registration system. First, the feed path moves the sheet in a process direction past the lateral sensor. Next, the sheet is registered by measuring a lateral position of one side edge of the sheet at a fixed reference using the lateral sensor and determining a lateral position error of the sheet using the lateral position measurement. After that, a sheet angular velocity is calculated based on the lateral position error using the registration controller. Then, the lateral position error is corrected using the at least one pair of registration nips to adjust the sheet by applying the sheet angular velocity to the sheet.
