Abstract
A ridged surface structure includes a plurality of parallelly arrayed and regularly spaced rectangular-sectioned ridges, each of the ridges may be cut at one or both lengthwise upper edges thereof to produce bevel surfaces at different positions, so that the bevel surfaces on the lengthwise upper edges at the same side of the ridges together produce at least one engraved pattern, and multiple overlapped engraved patterns may therefore be produced on the ridged surface and observed at the same time from different viewing angles. The ridged surface structure may be produced with many different materials, including plastics, reflective materials, and low-reflective materials, and may be widely applied to mass-produced products on which multiple marks or designs are to be displayed at the same time without increasing the manufacturing cost of the products.
