A method for forming a stereoscopic pattern of a plastic floorboard, comprising: positioning a base board on a digital printing unit, wherein the base board has an outer surface; using the digital printing unit to print pigment on the outer surface of the base board according to a preset pattern to form a pattern layer, wherein the pattern of the pattern layer corresponds to or does not correspond to the stereoscopic pattern; using a first forming unit to form a protection layer on the pattern layer with a transparent melt plastic raw material; and using a second forming unit to form the stereoscopic pattern having a concave-convex structure on the protection layer.

A method for embossing a polymeric sheet with rounded embossments includes a step of providing an embossing system including a platen component and a press component. The press component includes a pressing plate and a plurality of embossing protrusions extending from the pressing plate. The plurality of embossing protrusions are arranged in a predetermined pattern. Advantageously, each embossing protrusion has curved sidewalls with only rounded edges if present. A polymeric sheet is placed on the platen component. The polymeric sheet is contacted with the press component at a sufficient temperature to form embossments on the polymeric sheet. Characteristically, the embossments are depressions in the polymeric sheet having rounded sidewalls and rounded edges
