A method and a device for the optical testing of objects during the production and/or packaging of cigarettes, in particular of cigarette packs and/or blanks for cigarette packs and/or overprints and/or print substrates on or for cigarette packs, with the aid of a suitable testing device. For at least one feature characterizing the test object, in particular in a visual respect, a set of feature-value alternatives for the corresponding feature that are stored in a memory is displayed on a display means. By means of an input device, one of the displayed feature values of the set of feature-value alternatives is selected. The testing device is automatically set up or preset for the subsequent testing operations, in particular an evaluating device and/or an illuminating device and/or a suitable light detector of the testing device, the selection of the feature value influencing the setting up of the testing device.

Method and device for visually inspecting objects to be tested during the production and/or packaging of cigarettes

A method for testing moving products having at least two layers, such as cigarette packages wrapped with film, wherein at least one layer of the product, namely an inner layer which is arranged further inwards, is covered at least regionally by at least one, at least partially transparent product layer, namely an outer layer which is arranged further outwards, wherein the outer layer of the product is illuminated under an angle of incidence of about 35&#xb0;, with light, in which the light that is reflected at this layer comprises at least 70%, at least 90%, or at least 95%, of linearly s-polarized light, the s-polarized component of the light reflected by the outer layer and/or of the light reflected by the inner layer and/or the p-polarized component of the light reflected by the outer layer and/or of the light reflected by the inner layer are recorded in each case using at least one suitable electrooptic recording element in the form of an image or partial image of the product and wherein the recorded s-polarized and/or the recorded p-polarized light component are evaluated in order to be able to draw conclusions relating to features of the outer layer and/or of the inner layer.
