ABSTRACT:
Methods and systems for making an electro-optical device suitable for use in an image forming system are described. The device includes photosensors, which are covered by filter layers, to sense the presence of color in a document. The methods and systems provide for leaving a first filter layer on a non-sensor area to prepare the device for a substantially uniform application of a second filter layer.
