In Tri-level xerography, the control of the modulated levels creates a new set of problems, which did not plague the usual binary levels in normal xerography. One of the many concerns is controlling overshoot of the mid-level exposure so that the signal does not invade into the high-level exposure. Another concern is to maintain adequate signal width, which correlates well with the desired output pattern.
