Abstract
An imaging device includes a substantially continuous web of media; a web transport system configured to transport the continuous web along a web path; and a print station positioned along the web path and configured to apply ink to a first side of the continuous web to form images thereon. An image sensor is positioned downstream from the print station along the web path to scan a second side of the continuous web opposite from the first side. The image sensor is configured to generate a reflectance signal indicative of a reflectance of light from the second side of the continuous web. A controller is operably coupled to receive the reflectance signal from the image sensor, and to adjust at least one print process parameter based on the reflectance signal while the imaging device is performing print operations.
