The thickness of a moisture film on a printing roller is measured by directing two series of pulses of radiation on to the film, one of the series being of wavelength 2À95 Á, and comparing the intensities of the two series of pulses after reflection from the printing roller and absorption by the film. The second series of pulses, a reference series, preferably has a wavelength of 2À55Á. Radiation from a Nernst lamp 2, Fig. 1 with a linear filament is alternately reflected and transmitted by mirrors and apertures on a wheel 4 rotated by an air motor 57 to pass through filters 12, 15 and fall on the printing roller 10. Radiation reflected therefrom is reflected on to an indium antimonide photo-resistor 17. The pulses from photo-resistor 17 are separated by AND gates 22, 21, Fig. 3 (not shown) into measuring and reference pulse trains 34, 33, which are respectively applied to integrators 24, 23 connected to a crossed-coil ratio measuring instrument 25. The gates 21, 22 are opened by a bi-stable multivibrator 20 operated by the pulses from photoresistor 17 after delay and shaping. A counter 27 is provided to ensure that equal numbers of measuring and reference pulses are fed to the integrators 24, 23. In other embodiments, Figs. 4 and 5 (not shown) the counter 27 is fed from a trigger circuit receiving pulses from a photoelectric pick-up in one or other of the radiation pulse paths, or from a free-running multi-vibrator synchronized by the pulses from photo-resistor 17.
