and wherein the pressure is applied for between 1 to 20 seconds such that an outer periphery of the nail art achieves a gentle curve. ### Claim 2 (depends on 1) The method for preparing a nail art of claim 1, further comprising: before applying the pressure, disposing at least one or more process films between the pre-coating layer and the mold. ### Claim 3 (depends on 2) The method for preparing a nail art of claim 2, wherein a melting point of the process film is higher than the temperature of the mold. ### Claim 4 (depends on 2) The method for preparing a nail art of claim 2, wherein one to three process films are disposed between the pre-coating layer and the mold. ### Claim 5 (depends on 2) The method for preparing a nail art of claim 2, wherein the process film has a thickness of 9 μm to 188 μm. ### Claim 6 (depends on 5) The method for preparing a nail art of claim 5, wherein the pre-coating layer includes a UV-curable raw material, a photoinitiator, and a resin. ### Claim 7 (depends on 6) The method for preparing a nail art of claim 6, wherein the pre-coating layer includes: 30 wt % to 58 wt % of the UV-curable raw material, 0.1 wt % to 20 wt % of the photoinitiator, and 40 wt % to 55 wt % of the resin, in a solid content. ### Claim 8 (depends on 6) The method for preparing a nail art of claim 6, wherein the UV-curable raw material includes at least any one selected from the group consisting of urethane acrylate-based oligomers, polyester acrylate-based oligomers, polyether acrylate-based oligomers, epoxy acrylate-based oligomers, polycarbonate acrylate-based oligomers, silicone acrylate-based oligomers, and acryl acrylate-based oligomers. ### Claim 9 (depends on 6) The method for preparing a nail art of claim 6, wherein the UV-curable raw material includes the urethane acrylate-based oligomer. ### Claim 10 (depends on 6) The method for preparing a nail art of claim 6, wherein the photoinitiator has an absorption wavelength band in a range of 200 nm to 600 nm. ### Claim 11 (depends on 6) The method for preparing a nail art of claim 6, wherein the resin includes at least any one selected from the group consisting of acryl-based resins, nitrocellulose resins, urethane-based resins, acetic acid resins, ester-based resins, vinyl chloride resins, and styrene resins. ### Claim 12 (depends on 6) The method for preparing a nail art of claim 6, wherein the resin is a thermoplastic resin having a glass transition temperature (Tg) of 30° C. to 200° C. ### Claim 13 (depends on 5) The method for preparing a nail art of claim 5, wherein the substrate layer includes an adhesive layer. ### Claim 14 (depends on 13) The method for preparing a nail art of claim 13, wherein the substrate layer further includes a design layer disposed between the adhesive layer and the coating layer.
