Patent ID: RE43855

Claim:
A method of making a printed panel comprising a substantially imperforate substrate and having a design printed thereon, the design comprising a durable image material design layer adhered to a print pattern which subdivides the substantially imperforate substrate into a plurality of discrete printed areas and/or a plurality of discrete non-printed areas, the method comprising: forming said print pattern on said substantially imperforate substrate to form a patterned substrate; and presenting a design-generating medium comprising UV-curable ink to the patterned substrate , said presenting comprising digitally inkjet printing said UV-curable ink to form an imaged substrate without regard to whether the design-generating medium is being presented to areas of the print pattern or to areas outside the print pattern; and UV-curing the UV-curable ink into a UV-cured ink; wherein the design-generating medium and UV-curing causes the durable image material design layer to be formed only within the print pattern but and not outside the print pattern, and wherein the design-generating medium causes either (i) no image material to be formed on the areas outside the print pattern, or (ii) only non-durable image material to be formed on the areas outside the print pattern , which non-durable image material does not have good adhesion to the substantially imperforate substrate ; wherein , after said UV-curing, the durable image material design layer comprises UV-cured ink; and wherein non-durable image material is defined as material which can be substantially removed by water-jetting at a pressure of 2,000 lb/in 2 (140 kg/cm 2 ) with a water flow rate of 15 liters/minute and any durable image material with good adhesion to the substrate will remain substantially not removed by water-jetting at a pressure of 2,000 lb/in 2 (140 kg/cm 2 ) with a water flow rate of 15 liters/minute , wherein said substantially imperforate substrate is coated with a UV-curable material, said UV-curable material is partially cured, image material is applied to form said print pattern, and said image material is partially cured and said UV-curable material is fully cured .
