METHOD FOR MANUFACTURING SHEET FORMING MOLD, AND SHEET FORMING MOLD AND RETROREFLECTIVE SHEET

摘要

The present invention relates to a method for manufacturing a sheet forming mold, and a sheet forming mold and a retroreflective sheet, and to a sheet forming mold for forming a retroreflective sheet, a method for manufacturing the sheet forming mold, and the retroreflective sheet manufactured by using the sheet forming mold. One embodiment of the present invention relates to the method for manufacturing the sheet forming mold forming a cube corner retroreflective sheet by using a flake assembly in which a plurality of flakes are aligned, comprising the steps of: preparing the flake assembly having a plurality of array lines, which are a boundary line between the adjacent flakes, by aligning the flakes such that the lateral sides of each flake come into contact with each other; forming a plurality of cube corner mold patterns having triangular pyramid shapes on the upper surface of a flake assembly array; and changing the shapes of the cube corner mold patterns on the upper surface of the array by moving at least one flake of the flake assembly in the direction of the array line.
