  • Apparatus for measuring opaque medium coverage of a translucent sheet
    Patent number: 4832495
    Abstract: An apparatus for measuring the relative coverage of a predetermined portion of a sheet of translucent material with an opaque medium such as ink or photographic emulsion, comprising: a light source for providing a relatively constant intensity source of light over a predetermined measuring area; a positioning device for positioning the predetermined portion of the sheet of material to be measured over the predetermined measuring area of the light source; a light measuring device for measuring the relative amount of light from the light source which is transmitted through the predetermined portion of the sheet of material to be measured, whereby the relative amount of opaque medium coverage of the portion of the sheet to be measured is readily determinable by comparison of the measured amount of light transmitted through the predetermined portion of the sheet to be measured with predetermined calibration values.
