Techniques are disclosed for stitching images printed by a multi-head printer in a manner that is relatively insensitive to misregistration of the image segments. The method includes providing a wafer having an active surface and dividing the wafer into a plurality of portions. The content is presented in a presentation skin selected from a number of available presentation skins. The control circuitry controls a primary winding of the transformer to receive power during the charging period and controls a secondary winding of the transformer to discharge power to the LED light source during the discharging period. The central monitoring system includes a database for storing and retrieving at least a portion of the generated information from each base system.
