Abstract
The heat sensitive made polarized hidden image starts from making polarized light reflective plate, printing reflective layer on the back of the polarized plate of the usual photographic display, selecting stretch way produced plastic film to make polarized image carrier, applying heat sensitive treatment to the polarized image carrier, on which instantly heating the profile of the image with the temperature being the marginal one to make it change from solid to liquid, with the heated molecules moving aimlessly, confounding the neat and polarized media feature of the stretch made molecule, losing polarized effect to change into common transparent film, combining the heated image carrier thin film to the polarized reflective plate to form its hidden image. It is convenient in material selection, with sufficient supply of the polarized plate and the stretch plastic film market, clearer pattern than printing, simple of equipment and low in production cost.
Description
Technical field
The present invention relates to the method for making of the stealthy image of a kind of polarisation, mainly use the test of polarisation product and false proof.
Background technology
Polarisation phenomenon (polarized light phenomenon) is the marvellous spontaneous phenomenon that early be it is found that and pay attention to.In recent years, people make polaroid, and it is widely applied on the photoelectricity screen.Yet make the stealthy image of polarisation, the test that it is applied in the polarisation product with false proof on but make progress very slow.Have only the precious profit of the U.S. to come company to utilize print process to make polarisation test pieces (POLARIZED TESTLABEL), specialize in the usefulness of polarisation sunglasses test.China's year needs 2,000 ten thousand of this test pieces, is worth 4,000 ten thousand Renminbi all by U.S.'s import.The basic structure that above-mentioned print process is made the polarisation test pieces is: will contain polarisation medium powder and make the side that transparent ink is printed on light polarizing film (sheet), and make the printing figure layer that the last naked eyes of local cover are difficult for seeing on the light polarizing film.Like this, in the not zone polarisation refraction for once of seal layer, and produce the refraction of secondary polarisation on this light polarizing film in the zone that the seal layer is being arranged.Then the polaroid back side commonly used on the photoelectricity screen is stamped the polarisation refraction in reflection horizon and just formed black, thereby obtain testing effect with the refraction of secondary polarisation.The shortcoming that print process is made the polarisation test pieces has: need add a cover obscuring layer to eliminate the printing vestige; Complex manufacturing technology, the cost height; Contain polarisation medium powder and make transparent ink price height, be difficult for buying.
Summary of the invention
Purpose of the present invention just provides a kind of method of making the stealthy image of polarisation with heat sensitive process, adds a cover obscuring layer to eliminate the printing vestige with the need that the solution prior art exists; Complex manufacturing technology, the cost height; Raw material is difficult for the problem of purchase.
Technical scheme of the present invention is: this method may further comprise the steps:
(1) makes the polarisation reflector plate: the polaroid back side commonly used on the photoelectricity screen is stamped the reflection horizon with the silver slurry;
(2) select for use the plastic sheeting of pulling method production to make the polarisation image carrier;
(3) the polarisation image carrier being made temperature-sensitive handles: lines and stone according to the image of required making on described polarisation image carrier carry out transient heating to it, its heating-up temperature is liquid for this polarisation image carrier material solid-state transfers to faces Jie's temperature, making the molecule that is heated the zone during heating not have thread moves, upset originally with pulling method produce molecules align neat, have the characteristic of polarisation medium, lose the polarisation effect and become the normal transparent film.
(4) will be compound on the described polarisation reflector plate through the polarisation image carrier film that temperature-sensitive is handled, the stealthy image of polarisation.
Described reflection horizon is a silver slurry (aluminium powder).
PE, PVC, PP or PET film that described polarisation image carrier can adopt pulling method to produce.
Described temperature-sensitive is handled and is adopted laser engraving machine to carry out, its concrete operations step is: with the image input common laser engraving machine of required making, adjust power and focal length, make it reach engraving plane temperature and solid-stately transfer liquid Jie's temperature of facing to for what will carve carrier mass, when engraving machine moves like this, light beam is heated to being carried out part moment by the engraving film with the figure cabling, and being heated the zone becomes the normal transparent film.
The present invention and print process contrast have following three big advantages:
1. selection is convenient, polaroid and stretched plastic film ample supply of commodities on the market.
2. print process need be added a cover obscuring layer, prints vestige to eliminate, thereby has reduced the clear patterns degree.Heat sensitive process only changes its molecules align position amount, and with the naked eye difficult in appearance discovery distortion need not to add a cover obscuring layer, so the clear patterns degree is more clear than print process.
3. equipment is simple, and production cost is low.
The invention will be further described below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the schematic cross-section of polarisation image carrier of the present invention;
Fig. 2 is the schematic cross-section of the present invention through the polarisation image carrier of temperature-sensitive processing;
Fig. 3 is the schematic cross-section that polarisation image carrier that process temperature-sensitive shown in Figure 2 is handled and polarisation reflector plate become final products after compound.
Embodiment
Referring to Fig. 1～Fig. 3, concrete steps of the present invention are as follows:
1. polaroid 3 back sides commonly used on the photoelectricity screen are stamped the silver slurry as reflection horizon 4.Be imprinted on the silver slurry of doing reflection horizon 4 on the polaroid, add varnish by aluminium powder and make, because color, is commonly called as the silver slurry as silver color.Used silver slurry is that a kind of of conventional printing ink sold in market, and printing also is conventional printing, the also available silk screen seal of available gravure.
2. select for use plastic sheeting that pulling method produces as PE, PVC, PP, PET etc., make polarisation image carrier 1.
3. the polarisation image carrier being made temperature-sensitive handles: selectively to 1 transient heating of polarisation image carrier, heating region loses the polarisation effect and becomes normal transparent film 2 according to the image of required making.
The instantiation that temperature-sensitive is handled: with the image input common laser engraving machine of required making, adjust power and focal length, make it reach engraving plane temperature and solid-stately transfer liquid Jie's temperature of facing to for what will carve carrier mass.As select the PET film for use, then temperature is transferred to 21 ℃, when engraving machine moves like this, light beam was heated 0.2～0.4 second to being carried out part moment by the engraving film with the figure cabling, the position of being heated reaches and faces Jie's temperature, its molecule does not have thread and moves, upset originally with pulling method produce molecules align neat, have the characteristic of polarisation medium, lose the polarisation effect and become the normal transparent film.
4. will be compound on the polarisation reflector plate through the film that temperature-sensitive is handled, promptly become the polaroid with the stealthy image of polarisation shown in Figure 3.To handle the polarisation carrier thin film that has the image of diving through temperature-sensitive and be compound on the nothing silver slurry face on the polaroid that is printed on the reflection horizon, and utilize the image effect of silver slurry reflection increase polarisation image, thereby reach in white and black effect with gummed method (not heating).
