Definitions

  • the present invention relates to the production of a color laser image observable in three dimensions. It finds applications particularly in identity images dedicated to official documents: identity cards, credit cards, vital cards, passports, driving licenses, secure entry badges, etc.
  • the modern identification cards are composed of a plastic support, comprising various decorative motifs, identification, or anti-counterfeiting, covered by a transparent protective sheet.
  • the transparent protective sheet is hot welded and under strong pressure on the plastic support of the document. This operation is called “rolling" according to the professional language.
  • the identity documents In addition to the printed motifs on the support, the identity documents must bear the identity photo of the owner. This identity photo is produced by a laser beam which through the transparent protective sheet, which will be named later "lasérisable”, generates gray levels, by carbonization in this protective sheet. A secure black and white image is thus obtained. It can not be replaced by a image printed by inkjet for example, without destroying the identity document.
  • Patent applications FR 01415 under the title “Built-in latent image personalization device” filed on April 7, 2010, and the patent application FR 11/00578 filed on 28 February 2011 , entitled “Method for forming a reflective high-performance color laser image and a document on which a color laser image is thus produced” describes an array comprising a matrix of pixels consisting of sub-pixels in primary colors, embedded in a sheet Laserizable transparent protection.
  • RGB pixels the sub-pixels whose colors answer to the definition of independent colors, and correspond to the colors detected by the RGB rods (red, green, blue) of the human eye.
  • RGB rods red, green, blue
  • the present invention aims to overcome the disadvantages of the state of the art, by providing a color laser image with a three-dimensional vision.
  • the subject of the invention is a method for forming two distinct color laser images from an assembly comprising a support, a lasérisable protection sheet, a network of cylindrical optical lenses, pixels made up of sub-pixels. (RGB), printed with primary colors in the form of parallel columns (C1, C2, C3).
  • RGB sub-pixels.
  • the lens array is composed of cylindrical, parallel lenses, and the sub pixels (RGB) of columns parallel to the primary colors having their major axis located perpendicularly to that of the long axis of the cylindrical lenses of the lens array.
  • the sub-pixel array (RGB) is printed on the laserizable, offset, ink jet, thermal transfer, or other technique. It can according to one embodiment of the invention be printed on the support.
  • a second manufacturing step called "rolling" the lasérisable protective sheet, is heat-welded under pressure on the document support trapping the matrix of sub-pixels (RGB) between the lasérisable protective sheet, and the support of the document.
  • the lamination forms on the upper surface of the lasérisable protective sheet, the lens array.
  • the latter partially or totally overlaps the matrix of sub pixels (RGB).
  • the formation of the images, object of the invention, apparently restoring the relief image of the subject is carried out using a laser beam which carbonizes in its thickness the lasérisable protection sheet, with intensities or variable surfaces, opposite each sub-pixel, (RGB) the laser beam scanning columns (C1, C2, C3) of sub-pixels parallel to the large axis of these columns, and having a certain angle of incidence relative to the plane of the lens array, is deflected by the latter, shows by carbonization in the laserizable protective sheet, the gray levels of two separate images corresponding to the two stereoscopic images of the subject.
  • Ambient light follows the reverse path of the laser beam, and is reflected through the lens array at different angles, both color laser images that stereoscopically appear to the observer in a direction perpendicular to the plane of the document, as a single image in three dimensions.
  • the invention also relates to a document comprising a color laser image observable in three dimensions, by the implementation of the method above.
  • This document comprises a laserizable protective sheet on which a lens array has been hot printed. This sheet is at least partially carbonized by a laser beam.
  • Printed pixels have sub-pixels (RGB) in the form of columns. They are under the lens array and have the same surface.
  • the lasérisable protection sheet on which the lens array, the sub-pixel (RGB) columns and the document support are located, are capable of being laminated together.
  • the axis of the lens array is perpendicular to that of the column axis of sub pixels (RGB).
  • the formation of the three-dimensional observable color laser image is carried out on the document, by a laser beam that sweeps through the lens array, along the axis of the sub-pixel (RGB) columns at a first angle.
  • the two color laser images by inverse reflection of ambient light through the network of lenses, appear to the observer as a three-dimensional color laser image of the subject.
  • the figure 1 shows the section (13) of a lens array (10) according to the prior art.
  • the laser beams (11) and (12) having a certain angle of incidence with respect to the plane of the lens array, are deflected by the lenses and form gray levels (14) and (15) constituting two distinct black and white engraved by laser carbonization.
  • the figure 2 shows the section (20) of an assembly comprising the support (21), a matrix (25) of sub pixels (RGB) a laser beam (23) which by carbonization in the lasérisables protective sheet (22) forms non-transparent surfaces reflective (24) constituting the gray levels of a color laser image, according to the prior art.
  • the figure 3 shows a front view (30) of a matrix of sub pixels (RGB), (25) with primary colors.
  • the sub-pixels of this matrix have the form of parallel columns (C1, C2, C3) aligned along their major axis (31).
  • a network (10) of cylindrical lenses (L1, L2, L3) are aligned along their major axis (32), covers the matrix of sub pixels (RGB), (25).
  • the axes (31) of the sub-pixel columns and the axes (32) of the cylindrical lenses are perpendicular:
  • the figure 4 shows the section (40) along the axis (31) of the assembly shown in FIG. figure 3 .
  • the sub pixel matrix (RGB), (25) is shown here in section.
  • the cylindrical lenses (L1, L2, L3) shown in section perpendicular to their major axis (32) of the figure 3 are made on the lasérisable protection sheet (22).
  • Laserizable materials are, by way of non-limiting examples, polycarbonates, certain polyvinyl chlorides treated, acrylonitrile-butadiene-styrenes treated, or treated polyethylene terephthalates ethylene.
  • the lasérisable material is partially carbonized by the laser to form gray levels of a personalized image.
  • the lasérisable protection sheet is transparent and has a thickness of between 20 ⁇ m and 500 ⁇ m.
  • the laser scanning is performed along the axis (31) at a first angle of incidence (43) with respect to the plane of the lens array, forming the gray levels (46) of a first color laser image taken under a first angle of the subject, and at a second angle of incidence (44) with respect to the plane of the lens array, forming the gray levels (45) of a second color laser image, taken at a second angle of the subject.
  • the figure 5 shows in section (50) the reverse path of the ambient light which, through the array of lenses (L1, L2, L3) printed on the laserizable protective layer (22), is reflected on the matrix of sub pixels (RGB), (25), showing the gray levels (45) of the first color image, and (46) of the second color image, at the view (53) of the observer, located perpendicular to the plane of the lenses (L1 , L2, L3), according to the reflected rays (52) and (51) producing stereoscopic color laser vision of the subject in three dimensions.
  • the figure 6 shows in section (60) an assembly comprising the support (21) on which is laminated the lasérisable protection sheet (22), the matrix of sub pixels (RGB), (25) and opposite this matrix of sub pixels, the lens array (L1, L2, L3), (10).
  • This lens array is made by hot pressing on the sheet (22) during the lamination of the laserizable protective sheet (22) on the support (21), trapping the sub-pixel (RGB) columns (25) between the lasérisable protective sheet, (22) and the support (21).
