Abstract:
An apparatus (10) measures a spectral distribution of a translucent printed product (12) produced with a printing device. The apparatus (10) has an illuminating source (20) for illuminating the printed product (12), an optoelectronic measuring means (32) for measurer the transmittance value of a section of the spectrum of the light (26) transmitted through the printed product (12), an optical disperser (28) for dispersing the wavelengths of the transmitted light (26), and a light entry gap plane that is definitive for the disperser (28). The light entry gap plane that is definitive for the disperser (28) is created by the surface of the printed product (12) to be examined.
