A method for fabricating a device for displaying an interlaced image. The
method includes providing a film of transparent material and creating a
lens array in the film by forming parallel lens sets on a first side of
the film, and then bonding an interlaced image including sets of elongate
image elements to a second side of the film. Each of the lens sets is
configured with lenses for focusing light from one of the image elements
in a particular paired set of image elements rather than all the elements
as with lenticular material. The bonding of the interlaced image to the
film may include printing the interlaced image directly onto the second
side with the printing facilitated by the small lens array thickness.
Lens array creating includes embossing the lens sets into the film with a
flat die or cylinder/roller engraved with a reverse image of the lens
array.
