Pixel mapping and printing for micro lens arrays to achieve dual-axis activation of images

An apparatus adapted for to protect against counterfeiting, comprising:

• a film comprising a first surface including an array of lenses and a second surface opposite the first surface;
• a printed image proximate to the second surface, the printed image comprising pixels of frames of images arranged according to pixel mapping configured to provide dual-axis activation;
• and
• a substrate with a surface upon with the printed image and the film are supported.

A method of fabricating an anti-counterfeiting device, comprising:

• generating a print file defining dual-axis interlacing of a matrix of image frames;
• providing a transparent film comprising an array of lenses on a first surface;
• and
• based on the print file, printing an ink layer or providing a thin metal film with nanostructures on a second surface opposite the first surface, wherein the lenses of the array are round, hexagonal, or square-based lenses that are nested in the array,
• wherein the generating of the print file comprises providing pixel mapping of interlaced images that when viewed through the array of lenses provide image elements that are first activated to provide a first display effect when the anti-counterfeiting device is rotated about a first axis and that are activated to provide a second display effect when the anti-counterfeiting device is rotated about a second axis that is transverse to the first axis.
