ABSTRACT:
A printing system that dynamically adjusts the resolution at which printing will occur based on the lightness or darkness of the medium upon which the image will be printed is provided. The reflectivity of the medium upon which an image is to be printed is determined, and hence the relative lightness or darkness of the medium. The resolution at which the image will be printed is adjusted based on the determined reflectivity of the medium. For lighter colored mediums, sufficient contrast between the printed image and the medium upon which the image is printed can be maintained utilizing a lower resolution, while a higher resolution must be utilized to maintain sufficient contrast for darker colored mediums. Since it is not necessary to utilize the higher resolution for all mediums to ensure sufficient contrast is always provided, the amount of ink used by the printing system is reduced.
