Abstract
According to exemplary methods, a selection of a paper type for producing an image is received. A database of background suppression values associated with paper types is searched. Responsive to not finding a background suppression value associated with the paper type, the database is updated for the paper type. According to the method of updating, a page of the paper type is scanned and image data obtained by scanning the page is analyzed. Background luminance for the page is determined based on analyzing the image data. A background suppression value is calculated for the page based on the background luminance. The paper type and the background suppression value for the page are added to the database. The background suppression value is associated with the paper in the database.
