Graphic matter, such as words and images, is printed on a document in bound form, such as passport, by forming the graphic matter by laser printing steps on a temporary substrate and provisionally setting the graphic matter thus formed on the temporary substrate. Thereafter, the temporary substrate is juxtaposed with its face carrying the image in contact with the rear face of a transparent substrate, and the image is transferred to the rear face of this latter. Then the transparent substrate is juxtaposed to the final substrate that is intended to carry the image, with its rear face in contact with the front face of the final substrate, and the two substrates are laminated together, so that the image remains enclosed in the laminate and is visible from the front face of the transparent substrate as if it were printed on the final substrate.

[ We claim:] [19.] Apparatus for printing images on substrates forming part of a booklet, which comprises a laser printer having a printing section, comprising a metal cylinder, means for electrostatically charging said cylinder in selectively predetermined spots, and means for passing the electrostatically charged cylinder close enough to reservoirs of colors in powder form for said colors to be electrostatically attracted to said cylinder and form an image thereon, and means for passing a temporary substrate in contact with said cylinder, whereby to deposit said image on said temporary substrate, a setting section, said section comprising means for passing a temporary printing substrate through said section, means for provisionally heat-setting said image by applying heat thereto without applying pressure, and further comprising means for transferring the image from the temporary substrate onto a transparent substrate and means for laminating said transparent substrate to a final substrate forming part of a booklet.
