    measure dotgain on printing press with eye

    is it possible to measure simple dotgain on a press with the eye with some software?
    We have a densitometer, but it cannot measure dotgain

    Programs, calculating dot gain use Murray–Davies equation. That gives an opportunity to find dot gain, operating with density data in 0% raster poin (paper), 100 % raster point (actual ink density) and density data, mesured on the raster point you want to know dot gain for.
    There are online dot gain calculators, and excel tables, in order not to waste time, if you have no soft, compatible with your model of densitometr. =)

    Control raster scales can be informative for a trained eye, but not exact.
