Detailed Description
The first embodiment is as follows:
the present embodiment provides a system for forming a variable security pattern by a magneto-optical dual field, as shown in fig. 1, which includes: the surface of the printing substrate 1 is printed with an inducible ink coating, and the imaging photo-magnetic double field and the curing photo-magnetic double field are used for forming a variable security pattern on the surface of the printing substrate 1.
The printing substrate 1 is conveyed by a conveying mechanism and sequentially passes through the imaging photomagnetic double field and the curing photomagnetic double field; the imaging photo-magnetic dual-field system comprises a light field and a magnetic field which are respectively arranged above and below the printing substrate 1; the magnetic field 2 is a synchronous magnetic field which is transmitted by a magnetic field transmission mechanism to move synchronously with the printing substrate 1, namely move at the same linear speed, and is used for inducing the inducible ink coating printed on the surface of the printing substrate 1 to form a magnetic field pattern, and the optical field is used for curing the part, irradiated by the optical field, of the ink coating induced by the magnetic field; the curing photo-magnetic field comprises a curing light source 8 and a curing magnetic field 9, the curing light source 8 and the curing magnetic field 9 are respectively arranged above and below the printing substrate 1, so that the curing magnetic field 9 can induce the part of the ink coating which is not irradiated by the light field again, and the curing light source 8 is used for finally curing the ink coating of the whole pattern part. The curing light source 8 is vertically projected on the ink coating of the printing substrate 1 from above the printing substrate 1.
Specifically, the magnetic field 1 and/or the curing magnetic field 9 is a permanent magnetic field, an electromagnetic field or a crawler-type magnetic field; the shape of the permanent magnetic field or the electromagnetic field is a column shape, a horseshoe shape, a uniform magnetic field, a motor-driven spherical crown type magnetic field or a superposed magnetic field in the vertical direction, and the crawler-type magnetic field is a rubber magnetic type crawler belt or a crawler belt for clamping a magnetic plate.
The light field is a variable light field and is composed of a parallel light source 3 and a variable diaphragm, the parallel light source 3 comprises a light source and a parallel light lens, the light source adopts a UV light source or EB electron beams, and the corresponding inducible ink adopts UV curing ink or electron beam curing ink. The light from the collimated light source 3 is projected onto the surface of the printing substrate 1 through the variable diaphragm. The variable diaphragm is formed by a transparent film 4, a film transmission system 5, a fixed ink-jet system 6 and an ink-jet drying unit 7, wherein the film transmission system 5 transmits the transparent film 4 and the printing substrate 1 at the same linear speed, the ink-jet system 6 and the ink-jet drying unit 7 continuously work to continuously output a variable diaphragm pattern to the surface of the transmitted transparent film 4, and emergent light of the parallel light source 3 penetrates through the transparent film 4 with the diaphragm pattern and then is projected on the surface of the printing substrate 1, so that the diaphragm pattern is transferred to an ink coating on the surface of the printing substrate 1.
At this time, there may be a plurality of choices depending on the design:
the inducible ink pattern subjected to the primary partial exposure is subjected to partial exposure again through a second group of designed imaging photomagnetic double fields with the same principle as the photomagnetic double fields; theoretically, the imaging photomagnetic double field can enter the imaging photomagnetic double field for multiple times and be partially exposed for multiple times; considering the complexity of the process, one partial exposure or two partial exposures are generally selected to achieve a complex pattern.
After the final magnetic field and photo-curing, the inducible ink pattern is sequentially transmitted out of the last set of imaging photo-magnetic double fields, the exposed part is already cured, but the pigment alignment of the uncured part and the cured part is the same, so another magnetic field must be used again to change the pigment alignment of the uncured part, and therefore the curing magnetic field is used to induce the pigment flakes of the uncured part again, and then the pigment flakes enter the irradiation area of the curing light field to be finally cured.
In fact, the preparation method of the above-mentioned variable optical fence film includes the following modes:

The basic principle of the thermal transfer technology is similar to that of the thermal technology; the thermal head is contacted with the thermal transfer ribbon and the transparent base material film in sequence, and the coloring material on the thermal transfer ribbon is transferred and melted on the transparent base material film to form a pattern;
2. preparing a variable diaphragm film technology by ink-jet printing: using a piezoelectric ink-jet technology, and carrying out online jet printing on a variable pattern on the transparent film by using a nozzle;

The transparent film 40 can be prepared into a closed loop and then continuously recycled.
After the printing substrate is conveyed into the area which can be induced by the synchronous magnetic field, the pigment flakes in the ink pattern are aligned under the induction of the magnetic field; because the printing substrate of the inducible ink pattern and the synchronous magnetic field are relatively static, the printing substrate of the inducible ink pattern and the synchronous magnetic field synchronously enter the lower area of the light field; at this time, the transparent film 40 is also in synchronous transmission, and the pre-prepared diaphragm pattern is continuously output; after the parallel light source 30 passes through the diaphragm pattern, the diaphragm pattern is exposed and cured in the inducible ink pattern, and after the diaphragm pattern is exposed, the inducible ink pattern is sequentially transmitted out of the light field and the synchronous magnetic field.
Example three:
the present embodiment is similar to the second embodiment, except that the light field in the imaging photo-magnetic dual field is different, specifically as shown in fig. 3, the light field is composed of a parallel light source 300 and a fixed diaphragm, the fixed diaphragm is formed by a transparent film 400 with continuous pre-patterns and a fixed light shielding body 500, the transparent film 400 circularly drives at the same linear velocity as the printing substrate, the light shielding body 500 is provided with a light transmitting seam, the transparent film 400 moves through the light shielding body 500, the parallel light source 300 is disposed above the light shielding body 500, and sequentially penetrates through the transparent film 500 and the light transmitting seam to be projected on the ink coating of the printing substrate, and the pre-patterns on the transparent film 400 exposed by the light transmitting seam of the light shielding body are partially transferred into the ink coating on the surface of the printing substrate.
Example four:
the present embodiment is similar to the second embodiment, except that the light field in the imaging photomagnetic dual field is different, the light field employs a pulsed projection diaphragm, which includes a parallel light source and a pulsed transparent film with pre-formed patterns, the parallel light source is disposed above the transparent film, each pulse transmission of the transparent film causes one or a group of patterns thereon to be located between the parallel light source and the printing substrate, and the emergent light of the parallel light source is projected on the ink coating on the surface of the printing substrate via the patterns of the transparent film, so as to transfer the patterns into the ink coating.
Example five:
this embodiment is similar to any one of the first to fourth embodiments, except that the setting of the curing magnetic field is different, specifically, as shown in fig. 4, one pole of the curing magnetic field 90 is disposed above the printing substrate 100, and the other pole is disposed below the printing substrate 100. Moreover, the one pole and the other pole of the curing magnetic field 90 are vertically symmetrical relative to the surface of the printing substrate 100, or are inclined relative to the surface of the printing substrate, so that the connecting line of the two poles and the printing substrate are not vertical to form an included angle, and the included angle is well controlled, so that the effect of lateral face encodable invisibility can be formed.
Example six:

Because the surfaces of the two-dimensional codes and the variable codes which need the ink coating are smooth enough, the imaging photo-magnetic double field adopts the embodiment, and the magnetic field of the curing photo-magnetic double field can adopt one of the first embodiment and the fifth embodiment.
It should be noted that, except for the fifth embodiment, the curing magnetic field and the imaging photo-magnetic field of the other embodiments are both disposed below the printing substrate, and the N \ S poles of the two magnetic fields are disposed in opposite directions.
