Abstract
Plastic flooring contains: a substrate, a printing layer, and an abrasion resistance layer which are delivered into a rolling machine so that the rolling machine presses the substrate, the printing layer, and the abrasion resistance layer together. The substrate includes at least one soft film layer and at least one hard film layer, the printing layer forms on the substrate and has a convex portion and a concave portion, and the abrasion resistance layer forms on the printing layer. The rolling machine includes two delivery rollers, a guiding roller, and a pattern roller. The pattern roller has pressing patterns, and the pressing patterns have a depressed part and a raised part. When the substrate, the printing layer, and the abrasion resistance layer are pressed together, the convex portion corresponds to the depressed part and the concave portion corresponds to the raised part by using the registration transferring system.
