A radiographic method is proposed and then applied to infer the continuum part of the hard X-ray spectrum of a 4.7 kJ Plasma Focus from differential absorption measurements on metals. Copper, nickel, titanium and silver samples with thicknesses spanning between 0.1 and 10 mm were employed as filters. The X-ray radiation was detected using a standard radiographic screen-film system.  The results show the  presence of a dominant peak around 75 keV with significant spectral components in the range of 40 to 200 keV. The method is easy to  follow, inexpensive, and allows for calibrated, single shot, spectral  measurements.
