a spectrometer is sending light through your sample and detecting how much of this light is absorbed by the sample.so if you add fingerprints (or any other type of extraneous material, like precipitate) that block light going through the sample, you will be changing this measurement. if you change the measurement you will not be able to repeat the experiment and get the same results....
