Abstract: The present invention relates to radiometric measurement of a thin fluid film using absorption of IR radiation. At least one IR radiator is directed to send signals to an IR detector via a bed on which the fluid film is placed. The IR detector is set to receive IR radiation in a band around a characteristic absorption band of the fluid of the fluid film. The invention is developed for printing presses, where the thickness of fountain solution on the printing plate and the proportion of printing ink in an emulsion of printing ink and fountain solution may be controlled.

Abstract: An apparatus for radiometric measurement of thin fluid films includes a housing (1) enclosing means of radiation, a radiation guide, a reflector (4) and one or more detectors (5). The means of radiation is normally an IR radiator (2). The radiation guide is either a radiation tube (3) or a radiation cone (7). The reflector (4) is of the type non-imagining optics. If there is more than one detector (5) normally at least one detector is a reference detector.
