Manufacturing decorative panels by using a web-fed inkjet printer. During the feeding of the to-be-printed substrate, the tension of the substrate is controlled by a dancer unit (720) which includes a dancer roll (200), having a connector (120) on both side ends of said roll, and wherein both connectors (120) are connected to a pair of parallel guiders (110) for floating said roll along a floating path (210); and wherein the step of controlling comprises the step of moving one guider (110) of said pair of guiders (110) parallel to said floating path (210) whereby the dancer roll (200) is tilted.

A method of producing a building panel, including: providing a core, applying a balancing layer having a first moisture content on a first surface of the core, the balancing layer comprising a sheet impregnated with a thermosetting binder, applying a surface layer having a second moisture content on a second surface of the core, the surface layer comprising a thermosetting binder, adjusting the first moisture content of the balancing layer such that the first moisture content of the balancing layer is higher than the second moisture content of the surface layer prior to curing, and curing the surface layer and the balancing layer by applying heat and pressure. Also, a semi-finished product adapted to be cured for forming a building panel.

A decorative laminate lay-up used in the manufacture of decorative laminates includes a decorative laminate sheet assembly composed of resin impregnated paper layers and a textured release sheet positioned on a top surface of the decorative laminate sheet assembly. The textured release sheet provides a textured surface to decorative laminates resulting from processing of the decorative laminate sheet assembly, wherein the textured release sheet includes a textured surface exhibiting superhydrophobicity, self-cleaning and low surface energy.

A decorative laminate lay-up used in the manufacture of decorative laminates includes a decorative laminate sheet assembly composed of resin impregnated paper layers and a textured release sheet positioned on a top surface of the decorative laminate sheet assembly. The textured release sheet provides a textured surface to decorative laminates resulting from processing of the decorative laminate sheet assembly, wherein the textured release sheet includes a textured surface exhibiting anti-reflective, hydrophobic and oleophobic characteristics leading to a fingerprint proof surface.

A method for producing a panel including a core and a decorative surface layer is disclosed. The method includes the step of applying a dry powder layer on the core. The method includes the step of applying steam on a dry powder layer on the core. Thereafter heat and pressure are applied to the powder layer in order to bond the powder together.

One aspect of the present specification provides an eco-friendly semi-noncombustible exterior material including: a core part (10) formed by impregnating a paper or fabric base with a triazole-modified phenolic resin; an outer skin (20) formed by impregnating a paper substrate with a melamine resin and joined to at least one surface of the core part; and a UV film (30) formed on at least one surface of the outer skin, and containing a polymethyl methacrylate resin.

A system and related methods for high-resolution digital printing on wood-based substrates for exterior applications or outdoor use. Textured wood-based substrates include, but are not limited to, plywood, wood planks, oriented-strand board (OSB), laminated strand lumber (LSL), laminated veneer lumber (LVL), paper board, and various forms of engineered wood. A manufactured or engineered wood product with an engineered orientation is used as the base substrate to minimize deformation. A resin-impregnated paper overlay, which may include a special adhesion-promoting primer layer, is placed on the surface that will be subject to exposure outdoors. An image or images are printed using UV-resistant inks or film coatings, and a protective layer applied over the printed ink. The elasticity of the ink or film coating and the protective layer should match the protective overlay.
