Summary:A system and method for determining a level of effective residual ink concentration (ERIC) in a piece of recycled paper. The piece of paper is illuminated with a beam of radiation and an amount of the beam of radiation reflected and transmitted by the piece of paper is measured. The level of ERIC is determined as a function of the reflected and transmitted radiation.
