    Abstract: The disclosure relates to acoustic panels and methods for preparing them. The disclosure relates more particularly to panels having a porous facing and to methods for making such panels. One aspect of the disclosure is an acoustic panel comprising a base structure. The base structure has one or more edges, an outward major surface having a total area, and an inward major surface opposing the outward major surface. The base structure has a noise reduction coefficient (NRC) of at least about 0.3. The panel includes a coating layer directly disposed on the outward major surface of the base structure, the coating layer being formed of an open-cell foam. The coating layer has an exterior major surface opposing the outward major surface of the base structure. The coating layer is substantially scattering for light in the wavelength range of 380 nm to 780 nm, and has an absorption coefficient of less than 0.5 for acoustic frequencies in the range of 100 Hz to 10,000 Hz.

    Abstract: A system for coating of a donor material onto a laser radiation transparent substrate, the system including a donor material applicator, applying donor material to the laser radiation transparent substrate, a multi-pass precise donor material thickness determiner for providing a desired thickness of the donor material on the laser radiation transparent substrate and including a linearly displaceable blade support, a layer thickness uniformizing blade lockably pivotably mounted onto the linearly displaceable blade support about a pivot axis, the blade having a straight edge and a blade position maintainer operative for maintaining the straight edge at a desired separation distance from the laser radiation transparent substrate, the separation distance being uniform along the straight edge of the layer thickness uniformizing blade.
