PURPOSE: Provided is a method for producing a coated nonwoven material for inkjet printing which has excellent water resistance and light resistance so it is blast-spinning non-directional polyethylene fiber having excellent durability and high density to form. CONSTITUTION: The coated nonwoven material is prepared by: mixing resin selected from the group consisting of polyvinyl alcohol, acrylic resin, polyvinyl acetate and latex with pigment selected from the group consisting of silica, calcium carbonate, clay, talc, titanium dioxide and plastic pigment in a weight ratio of pigment to resin of about 10:2-8 to make under-coating liquid; under-coating in under-coating liquid of quantity being 3.0-10.0g/m¬2 by using one method selected from the group consisting of blade, bar coater, roll coater and air knife coater; drying coated layer by using hot wind or cylinder dryer; mixing pigment selected from the group consisting of silica, calcium carbonate and clay with adhesive selected from the group consisting of polyvinyl alcohol, acrylic resin, polyvinyl acetate and latex in a composite ratio of pigment to adhesive of 10:2-9 to make top-coating liquid; top-coating in top-coating liquid of quantity being 10.0-35.0g/m¬2 by using one method selected from the group consisting of blade coater, roll coater and air knife coater; and then drying coated layer by using hot wind and cylinder dryer. In case of necessity, non-ionic defoamer, ink fixative, dispersing agent and water proof agent. Water proof agent is selected from the group consisting of ammonium zirconium carbonate, ammonium zirconium acrylate, glyoxal and epoxy type resin.
