When a clear layer is coated on a diffusing background, light is reflected multiple times within the transparent layer between the background and the air-layer interface. If the background is lit in one point, the angular distribution of the scattered light and Fresnel's angular reflectance of the interface induces a specific irradiance pattern on...

When a print is coated with a transparent layer, such as a lamination film or a varnish layer, its color can be modified compared to the uncoated version due to multiple reflections between the layer-air interface and the inked substrate. These interreflections involve a multiple-con-volution process between the halftone pattern and a ring-shaped l...

Many prints are coated to increase their resistance or to enhance their appearance. Applying a smooth transparent layer on a print darkens and saturates its color, an easily observable effect which can be predicted in order to obtain better color management of coated surfaces and ink saving. A model was thus developed which describes the reflectanc...

... It was particularly observed at the early age of astronomical photography as the interreflections inside the imaging glass plates, over-layered by a diffusing photosensitive emulsion, induced a halo around the brightest stars [5] as can be seen in Figure 1.A. This phenomenon has been fully modeled recently for glossy coating on halftone prints, with rather good accuracy in experimental verifications [6], [7]. ...
