A method of making a plastic flooring comprises steps of: A) providing a substrate and delivering the substrate to a rolling unit; B) delivering a printing layer, wherein the printing layer is blank and is delivered toward the rolling unit by way of a delivery roller mechanism; C) rolling, wherein the rolling unit rolls the substrate and the printing layer together so as to produce a plastic flooring material, and the printing layer has three-dimensional embossing; D) digital printing, wherein color material being printed on three-dimensional embossing of the printing layer by using a digital print unit; E) coating an abrasion resistant layer, wherein a coating unit coats wear-resistant materials of the abrasion resistant layer on the printing layer; and F) shaping, wherein the plastic flooring material is shaped so as to dry and harden the abrasion resistant layer; characterized in that the rolling unit includes five rollers which are a first roller set arranged on a machine frame, a second roller set, and a third roller set, wherein the second roller set has a second roller and multiple third rollers surrounding the second roller, wherein a diameter of the second roller is more than those of the multiple third rollers, the first roller set is located beside the substrate and has two adjacent first rollers arranged beside a first side of the second roller set so as to deliver the substrate to the second roller of the second roller set; the step C) rolling includes a first sub-step C1 in which the substrate is guided to the second roller by ways of the first roller set; the step C) rolling includes a second sub-step C2 in which the printing layer is delivered toward the second roller by the multiple third rollers so as to be rolled on the substrate; the step C) rolling includes a third sub-step C3 in which the substrate and the printing layer are rolled by using the third roller set, the third roller set being fixed beside a second side of the second roller set, wherein the third roller set includes multiple fourth rollers, wherein at least one of the multiple fourth rollers which has imprinting patterns so as to roll the substrate and the printing layer has three-dimensional embossing is formed thereon by ways of the imprinting patterns of the third roller set; the digital print unit includes a first platform mounted on a first base and includes an imprint mechanism located above the first platform; wherein the imprint mechanism has a material collector, a first end of which connects with a first supply source for supplying the color material, and a second end of the material collector has a feeding portion configured to output the color material; the imprint mechanism is controlled by the electronic control unit; the step D) digital printing includes a first sub-step D1 in which the plastic flooring material having the three-dimensional embossing is conveyed toward the first platform below the feeding portion; the step D) digital printing includes a second sub-step D2 in which the electronic control unit controls the imprint mechanism, and the feeding portion imprints the color material on the three-dimensional embossing of the printing layer based on a pattern setting of the electronic control unit; and the coating unit includes a second platform mounted on a second base and the coating unit includes a coating mechanism located above the second platform, a first end of the coating mechanism connects with a second supply source for supplying the wear-resistant materials, and a second end of the coating mechanism outputs the wear-resistant materials; the step E) coating the abrasion resistant layer includes a first sub-step E1 in which the plastic flooring material is moved toward the second platform below the coating mechanism; and the step E) coating the abrasion resistant layer includes a second sub-step E2 in which the coating mechanism is controlled by the electronic control unit to coat the wear-resistant materials on the printing layer. A) providing a substrate and delivering the substrate to a rolling unit; B) delivering a printing layer, wherein the printing layer is blank and is delivered toward the rolling unit by way of a delivery roller mechanism; C) rolling, wherein the rolling unit rolls the substrate and the printing layer together so as to produce a plastic flooring material, and the printing layer has three-dimensional embossing; D) digital printing, wherein color material being printed on three-dimensional embossing of the printing layer by using a digital print unit; E) coating an abrasion resistant layer, wherein a coating unit coats wear-resistant materials of the abrasion resistant layer on the printing layer; and F) shaping, wherein the plastic flooring material is shaped so as to dry and harden the abrasion resistant layer;
