Definitions
- TITLE MACHINE AND METHOD FOR HIGH SPEED PRINTING OF SECURE TICKETS
- the present invention relates to machines for printing secure titles, in particular identity cards.
- the present invention aims to constitute a printing machine without added ink which allows high-speed printing of secure titles by photographic projection of an image comprising variable data to be attached to a title.
- Printing machines are known which make it possible to print secure titles, for example identity cards, by laser screen printing on a polycarbonate element or by scanning printing.
- the aim of the invention is to overcome at least some of the aforementioned drawbacks and to propose a high-speed printing machine for secure vouchers, which is capable of combining the advantages of speed, reliability and quality for its implementation.
- the subject of the invention is a ticket printing machine comprising:
- an image projection device comprising a display and a photographic lens
- Image transfer means of at least one photosensitive negative film film to a positive film film comprising pressure rollers applying said negative film against the positive film.
- the image projection device includes means for backlighting the display.
- the printing machine comprises two image projection devices associated respectively with a front negative film and a back negative film and the image transfer means apply said front and back negative films on either side of the positive movie.
- the machine comprises a roller for winding the positive film and means for unwinding said positive film.
- the unwinding means comprise tensioning elements for guiding and keeping said films taut.
- the machine may further comprise means for controlling the means for unwinding said positive film as a function of visual cues preprinted on the positive film.
- the display comprises a monitor with a resolution greater than or substantially equal to three thousand eight hundred forty pixels by two thousand one hundred sixty pixels.
- the machine comprises reels for rewinding said negative film.
- the invention also relates to a method comprising the following steps:
- FIG 1 represents a printing machine according to the invention.
- FIG 2 shows a portion of a pellicle film with pre-printed data.
- FIG 3 represents the implementation steps of the printing machine of Figure 1.
- FIG. 1 illustrates a printing machine 1 provided for producing high-speed continuous-tone printing of secure titles 2, in particular identity cards, at the rate of at least eight hundred cards per hour.
- the machine 1 is designed to receive a positive film film 3 which may include pre-printed data 4 specific to the type of secure document 2 to be printed, such as a base map or elements for certification or prevention of falsification.
- the machine 1 may comprise a roller 5 for winding the positive film 3 and means 6 for unwinding said positive film 3, comprising in particular a motor 7 for driving in rotation the roll of positive film 5.
- Machine 1 also receives at least one negative film 8.
- negative film 8 is photosensitive. It may comprise for example a flexible support comprising a thickness of silver salts covered with a photosensitive varnish which evaporates when it is exposed to light.
- Machine 1 further comprises an image projection device 9, comprising a display 10 and a photographic lens 11.
- the projector 9 makes it possible to emit an image 12 from the display 10 on the photosensitive negative films 8 via the lens 11 so as to produce a photographic print of this image 12 on said films 8.
- the printing aims in particular to print by photosensitivity variable data 13 of the title holder 2 on the negative 8, before transfer to the positive 3 of these variable data printed 13 on the negative 8.
- Variable data 13 includes, for example, an identity photograph and civil status data of the holder.
- the display 10 comprises a high-resolution monitor, for example a screen of the "UHD-4K” type (for "ultra-high definition"), in particular with a resolution greater than or substantially equal to three-thousand-eight-hundred- forty pixels by two thousand one hundred and sixty pixels, so as to produce particularly detailed prints.
- a high-resolution monitor for example a screen of the "UHD-4K” type (for "ultra-high definition"), in particular with a resolution greater than or substantially equal to three-thousand-eight-hundred- forty pixels by two thousand one hundred and sixty pixels, so as to produce particularly detailed prints.
- the image projection device 9 may comprise means 14 for backlighting the display 10 and means for adjusting the backlighting, which makes it possible to adapt the backlighting to the tone of the positive which changes according to the type of security document to print.
- the display 10 is able to turn on and off at high frequency and a large number of times, which makes it possible to avoid the use of a specific mechanical shutter, in particular with a diaphragm, which is particularly expensive and fragile at frequencies of significant use.
- the machine 1 further comprises means for transferring images from the negative film to the positive film 14.
- the image transfer means 14 comprise pressure rollers 15 between which the films are sandwiched so as to apply the negative film 8 against the positive film 3.
- the unwinding of the positive film 3 allows both that it receives an impression from the negative film 8 on which it is applied by the pressure rollers 15, and at the same time that the positive film 3 causes the unwinding of the negative film 8 to which it is locally joined by support.
- the negative film stock 8 can be wound on an unwind roll 16 to facilitate its unwinding.
- the machine 1 may further comprise reels 17 for rewinding the negative films 8 to facilitate disposal.
- the printing machine 1 comprises twice the image projection device 9, each being associated respectively with a front negative film and a back negative film.
- the positive film 3 is then inserted between the recto 18 and verso 19 negative films so that the image transfer means 14 apply said negative films 18, 19 on either side of the positive film 3 to form a printed title 2 on both sides.
- the data previously printed 4 on the positive film 3 may include visual marks 20 regularly spaced on the positive film 3.
- the machine 1 may further comprise control means 21 of the unwinding means 6 of said positive film 3 according to the pre-printed data 4 on the positive film 3, in particular according to the visual cues 20.
- the unwinding means 6 may also comprise tensioning elements 22 allowing the films to be tensioned while guiding them, such as smooth rollers or rolling bearings.
- the control means 21 comprise visual sensors of the markers 20 and a computer coupled to the sensors to clock the unwinding of the films 3, 18, 19.
- the control means 21 can also be coupled to the image projection devices 9 for switching on and off the display 10 for each print of title 2 and to change the variable data 13 to be printed specific to each title 2.
- Figure 3 illustrates an example of the implementation of the secure document printing machine 1. This implementation can begin with a step E1 by which the positive 3 and negative films 18, 19 are unrolled substantially simultaneously until 'on the detection of one of the marks 20 provided on the positive film 3.
- Step E1 continues with a step E2 by which variable data 13 of the secure document 2 is displayed on the display 10 of the image projection device 9 and, substantially simultaneously, is projected via the photographic lens 11 of the image projection device 9 the display of the display 10 on the negative film 8.
- the printing process continues first with a step E3 during which the negative film 8 is pressed against the positive film 3 thanks to the transfer means 14, until an image from the negative film 8 is transferred onto the positive film 3 , then by a step E4, during which the negative pellicle film 8 is detached from the positive film 3. It is also possible at the same time to rewind the negative film 8 on its rewind reel 17.
- Steps E1, E2 and E3 are carried out under conditions of reduced darkness, for example in a dark room.
- step E4 can include known steps of lamination and cutting of the positive by punch so as to obtain a title 2 of standard format, and continue with a new step E l for a new printing of secure title 2.
