Print Registration Control

摘要

As we noted in March 2009, closed-loop process control can be defined as a system that continually monitors and adjusts a process to maintain a particular target value of an output or outputs (FIGURE 1). To improve the performance of positional accuracy, we tested a closed-loop system that uses a CyberOptics SE300 SPI to measure X, Y and A print offset (FIGURE 2). This information is then passed to the printer to make appropriate corrections to the print offset, as necessary.
