Method of patterning a surface of an object or a tool with nano and/or micro structure elements having dimensions in a range of 1 nanometer to 1 millimeter, comprising the steps of producing a flexible mask with said nano or micro structure pattern formed on a surface of said flexible mask, chemically activating said surface of the flexible mask and/or said surface to be patterned of the tool, placing said patterned surface of the flexible mask in contact with said surface to be patterned of the object or tool, promoting a covalent bonding reaction between said patterned surface of the flexible mask in contact with said surface to be patterned, removing the flexible mask from the tool whereby a layer of said flexible mask remains bonded to said surface to be patterned of the tool, etching said surface to be patterned of the tool whereby the bonded layer of flexible mask material resists etching. An anti-activation mask defining a periphery of the surface area to be patterned, or peripheries of the surface area to be patterned if there are a plurality of separate portions of surface area to be patterned, is deposited on the flexible mask prior to placing the patterned surface of the flexible mask on the surface to be patterned. The anti-activation mask prevents bonding of the flexible mask to the surface of the object or tool in areas where the anti-activation mask is present.

A method and an apparatus for printing a hologram by using a mask are provided. A method generates a hologram fringe pattern, splits the hologram fringe pattern on a hogel basis, generates the split hogels, masks a part of the generated hogel, and prints the masked hogel on a hologram medium. Accordingly, an empty space which occurs between hogels when a hologram is printed is prevented from being generated by using a mask, so that a fill factor can be effectively enhanced, and eventually, image quality of a hologram can be enhanced.
