Abstract:

Methods and apparatuses are provided for use in printing devices. In certain implementations, ink is printed to a first area of a print medium and a second area of the print medium. The ink is applied to the first area at a higher density than the second area. A first light scattering intensity value is measured from the first area and a second light scattering intensity value is measured from the second area. The print medium is categorized based on a comparison of the light scattering intensity values.
