Abstract: 1. A method for producing a panel (1), stretched over a frame (2), said panel (1) formed from a flexible and heat-shrinkable textile material, comprising: providing a fabric piece of said flexible textile material said flexible textile material comprising knitted synthetic textile threads; coating said flexible textile material on at least one of its sides by means with a coating mixture containing at least one polymer with elastomeric characteristics in the polymerized state and a covering coloring substance; said polymer contained in said coating mixture is polymerized; cutting a sheet from said flexible textile material whose dimensions are slightly greater than those of said frame (2); attaching said frame (2) to support (3), said frame (2) being made up of retaining profiled sections (2') forming a closed frame; engaging peripheral edges of said sheet in said retaining profiled sections (2'); and after engaging the peripheral edges of said sheet in said retaining profiled sections to eliminate any folds resulted during the panel production and/or insufficient stretch of the panel in some areas, further heating at least one zone of said sheet in order to bring about the heat shrinking of said flexible textile material. 2. The method according to claim 1, further comprising cutting edges of said sheet extending past said retaining profiled sections (2') flush with said retaining profiled sections (2'). 3. The method according to claim 1, wherein said synthetic textile threads constituting the basis of said flexible textile material include heat-shrinkable polyester threads capable to thermo-pressure. 4. The method according to claim 1, wherein said coating mixture further contains a flame retardant substance. 5. The production method according to claim 1, wherein said coating mixture consists of a paste, and said method further comprises depositing said paste in the form of at least one extruded rope over at least a part of the width of said flexible textile material, wherein said coating mixture penetrates into the meshes of said flexible textile material. 6. The method according to claim 5, wherein said polymer in said coating mixture contains polyurethane. 7. The method according to claim 1, wherein said covering coloring substance includes titanium oxide. 8. The method according to claim 1, wherein said covering coloring substance includes colored pigments. 9. The method according to claim 1, wherein said covering coloring substance includes decorative elements at least in a form chosen from the group comprising of powders, flakes, granules, films of mineral and/or synthetic substances, and/or a mixture thereof. 10. The method according to claim 1, wherein said coating step comprises printing said coating mixture on said flexible textile material said sheet is carried out. 11. The method according to claim 10, wherein said printing step comprises a digital printing technique. 12. The method according to claim 1, further comprising forming said frame (2) with retaining profiled sections (2') having two opposite clamping jaws. 13. A panel (1) stretched on frame (2) attached to a support (3), said frame (2) comprising retaining profiled sections (2') forming a closed frame, wherein said panel is formed from a sheet whose dimensions are slightly greater than those of said frame (2), said sheet being cut from a textile fabric produced from synthetic textile threads according to a knitting method in order to form meshes that can be deformed in all directions, this textile fabric being coated on at least one of its sides with a coating mixture containing at least one polymer having elastomeric characteristics in the polymerized state and a covering coloring substance, said polymer contained in said mixture being polymerized, peripheral edges of said sheet being engaged in said retaining profiled sections (2') constituting said frame (2), and said sheet being locally heated in order to bring about heat shrinking and tightening within said frame. 14. A panel (1) according to claim 13, wherein said synthetic textile threads include heat-shrinkable polyester threads and said polymer of said coating mixture contains polyurethane. 15. A panel (1) according to claim 13, wherein said coating mixture includes a flame retardant substance. 16. A panel (1) according to claim 13, wherein said covering coloring substance includes titanium oxide. 17. A panel (1) according to claim 13, wherein said covering coloring substance includes colored pigments. 18. A panel (1) according to claim 13, wherein said covering coloring substance includes decorative elements present in a form chosen from the group comprising powders, flakes, granules, films of mineral and/or synthetic substances and/or a mixture of these elements. 19. A panel (1) according to claim 13, further comprising at least one digitally printed image on at least a part of one said panel sides. 20. A panel (1) according to claim 19, wherein said printed image is chosen from the group comprising at least a decorative image, an advertising representation, a drawing, an inscription. 21. A panel (1) according to claim 13, wherein it has a surface treatment obtained by at least ultraviolet binding and/or molecular grafting. 22. A panel (1) according to claim 21, wherein said surface treatment provided said panel (1) properties chosen from the group comprising antiseptic, insecticidal, antistatic, and/or disinfectant properties.
