Does line speed affect color measurements on the SpectraTrend HT?


The lines speed does not matter. The flash rate is 5 per second. The only difference that line speed makes is that the view circle may be very slightly more oval in shape but this would not affect the color.

    Dear Tod,

    Is it a problem to move the line vibrating?

    Flutter at the spot of the measurement should be minimized if possible, Typically this is done with an idle roller at the location of the measurement spot. This will prevent the product from changing its orientation to the sensor that may result in variability in the color measurement. For small, regular, vibrations, a longer averaging time can also be used to smooth out vibration (angular reflection) effect during the sampling time.
