1. An image forming device for controlling fountain solution thickness on a non-reflective imaging member surface of a rotating imaging member, comprising:
a reflective substrate attached to the non-reflective imaging member surface at non-image forming regions along a first side gutter of the imaging member surface outside a imageable area of the imaging member surface to form a reflective surface on the otherwise non-reflective surface, the imaging member surface having a layer of fountain solution fluid dispensed on both the reflective surface and the non-reflective surface at a fountain solution dispense rate;
a light reflectance detector spatially separate from the imaging member surface forming a gap therebetween, the light reflectance detector configured to measure a light reflectance from the reflective surface with the fountain solution fluid layer thereon; and
a controller in communication with the light reflectance detector and the fountain solution applicator to modify the fountain solution dispense rate based on the measured light reflectance.
