Summary: | An imaging device includes a plurality of ink jets that eject drops of substantially clear ink onto print media. One of the print media and the substantially clear ink has a fluorescent characteristic and the other of the print media and the substantially clear ink is substantially non-fluorescent. The imaging device includes a fluorescence sensor that illuminates the print media and detects a fluorescence intensity of light received from the print media alone and from the print media and the drops of substantially clear ink ejected onto the media. A controller modifies an operating parameter of the imaging device with reference to ink drop masses identified with reference to the detected fluorescent intensities. |
