Grid image with bulge effect

摘要

The grid image has a diffractive grid structure, which is divided into multiple subelements, which are filled with continuous grid lines and which are separated from each other by separation areas running transverse to the grid lines. The continuous grid lines are arranged in the subelements with stepwise varying distances and with irregular interspersed gridline discontinuities. Independent claims are also included for the following: (1) a method for producing a grid image for representing a theme with an outline contour appearing with a shimmering three dimensional curve effect; (2) a safety element with a hologram element; (3) a data medium such as a bank note; and (4) a forming die for generating an embossed structure.
