The specific embodiment

At first with reference to Fig. 1, one section medium 1 to be printed is carried in the direction of arrow A, and this medium 1 comprises one section transparent material layer (transparent sheet material or transparent membrane) 2, and has the opaque barrier liner (release liner) 3 that contacts with the one first type surface.An advantage clearly is that barrier liner 3 makes one section transparent material layer 2 have certain rigidity, thereby making it to be convenient to handles.Transparent material layer 2 is preferably the mylar that thickness is approximately 70 microns.Opaque barrier liner 3 is preferably paper or the polypropylene that thickness is approximately 80 microns.

Fig. 3 represents the cross-sectional plane of medium 1.Be applied with pressure-sensitive emulsion binder layer 3a on the barrier liner 3, its typical thickness is 10 to 15 microns.Be applied with silicone layer 2a on the transparent material layer 2 that is formed by mylar, its typical thickness is approximately 3 to 5 microns.Silicone layer 2a contacts with adhesive layer 3a.Silicone layer 2a prevents that adhesive layer 3a and transparent material layer 2 from boning fully, and allows barrier liner 3 to leave transparent material layer 2 and be applied to again on the transparent material layer 2.This allows the label that has checked and uses barrier liner 3 again, so that protection is surperficial when being sent to use or storage place.

Printable media 1 is flowed to printer 5, and this printer 5 is a heat transfer printer, and it has print head 6 and colour band 7.Outside or inside at printer 5 are equipped with optical sensing devices (or photosensor) 8, and it is included in the light beam generator 9 and the detector 10 of the two opposite sides setting of medium 1 delivery conduit.

Detector 10 is by the output of conventional approach detection light beam generator 9, but therefore the light tight medium of any break beam will make detector 10 detected signal weakenings.Detector 10 detected signals can be used to control the operation of print head 6.For example, if because beam attenuation or be blocked and make detected signal sharply weaken, then signal processor 11 can detect this weakening as computing machine, and controls print head 6 conversely and print on transparent material layer 2.Clearly, should monitor and/or the delivery speed of control agent 1.But the time between the supervision peak signal and the delivery speed accuracy control of medium 1 be the position of the mark of printing so.

When printable media 1 passes through light beam, because the existence of opaque barrier liner 3, so detector 10 detected signal weakenings.Signal processor 11 is in response to the detection signal that weakens, to control print head 6 beginnings and to finish the required mark of back face printing on transparent material layer 2.That is to say that as shown in Figure 1, printer 5 is in the downside printing of transparent material layer 2.Surface ratio transparent material layer 2 opaque liners 3 coarse and the effective thickness additive incrementation make the roller of printer can not only clamp medium 1, and can with its accurate aligning so that on transparent material layer 2, print.

Use a computing machine to store the mark that need be printed onto on the medium 1, this computing machine can be identical with described signal processor 11, also can be different.Send this information, the format of the required mark of these printer 5 preferred process to printer 5.Particularly suitable preferred printer is by Astro-medIncorporated ofRhode Island the QLS-4100 series printer that USA provides.The printing speed of this printer can be up to 20.4 cels, but the most frequently used speed is 7.6 cels.Therefore, use this light-operated printer, per hour can produce nearly Britain's vehicle identification plate (52.1 * 11.1 centimetres) of 1200 standards automatically.

Consequent printed medium 15 is transported to a stacked station 17.Also be transported to stacked station 17 by ABS injection mo(u)lding and a segment base body 20 with a reflecting surface 22.The thickness of matrix 20 is generally 2.5 to 3.8 millimeters, is preferably 3.2 millimeters.Matrix 20 has a division board 23 that is covered with pressure sensitive adhesives layer (not shown).Adhesive layer can apply in advance, and promptly off-line applies, but also can apply in this process.When being transported to stacked station 17, removes matrix 20 division board 23.

The printed medium 15 and the segment base body 20 that comprise transparent material layer 2 and opaque barrier liner 3 all are shown as rectangle, and have right angle corner.But the turning of other shapes also is fine, and for example each parts 2,3,20 can have arc or radiused corners.

So the stacked compound 30 that forms is transported to the place of a back, removes opaque barrier liner 3 from transparent material layer 2 there, thus the Identifiaction plates that obtains finishing 40.Removing barrier liner 3 can carry out before or after being installed to label 30 on the vehicle, thereby made the surface that can protect label 30 in course of conveying.Silicone layer 2a will handle, precipitate or separate out by element, air-flow is handled operations such as (wind) and removed.

Transparent material layer 2 is as the lens of no coating reflecting surface 22, for it provides reflective characteristic.Because being used for the lens of reflecting surface 22 is simple transparent material layer 2, rather than the thick transparent base of some available technology adopting, so mark is clearer, and the specularity of label 40 higher (this is the cause shorter with reflection paths that penetrate owing to light), these 2 all is that the locomotive licence plate presses for.When using the reflecting surface 22 of coating, transparent material layer 2 can not damage or worsen the reflective characteristic of reflecting surface 22.

Above-mentioned explanation concentrates on so-called independent printing or " single-shot " printing.But, also may adopt so-called continuous, " in batches " or rolling printing, wherein one section printable media 1 ' comprises and has the rolling transparent material layer 2 of isolating back layer 3, and it is sketched the contours into the section of matrix size by cross-perforating 4 or is saved, as shown in Figure 4.Independent section is formed as has fillet 18.

With reference to Fig. 2 and 4, for clarity sake, printable media 1 ' (among Fig. 2) is shown as independent section, but it should be understood that medium 1 ' is continuous section or volume.Medium 1 ' is flowed to printer 5, as shown by arrow A.Pass in the process of light beam generator 9 a section, when " form " 12 that forms between the fillet 18 of the adjacent single section in the printable media 1 ' was located immediately in the beam path, it is maximum that detected signal reaches.This maximum detection signal corresponding to the material that weakens light beam between light beam generator 9 and detector 10 the most after a little while, for example when perforation 4 and light beam when being in line.When the material that weakens light beam between light beam generator 9 and detector 10 the most for a long time, then detected signal minimum.These two kinds have been shown among Fig. 2 extremely.By calibration in advance, can utilize the difference between peak signal and the minimum signal to control print head 6 back face printing mark on the first type surface of transparent material layer 2.

Apply on the nethermost surface that station 16 places are applied to adhesive agent printed medium 15 ', promptly on the print surface at adhesive agent.Can apply station 19a at barrier liner then one barrier liner is applied on this surface, avoid polluting with the protection adhesive agent.

To have the printed medium 15 ' that replenishes barrier liner then and be transported to stacked station 17.Also be transported to stacked station 17 by ABS injection mo(u)lding and the segment base body 20 that has a reflecting surface 22.The thickness of matrix 20 is generally 2.5 to 3.8 millimeters, is preferably 3.2 millimeters.

With printed medium 15 ' with before matrix 20 is aimed at, if applied additional barrier liner in advance, then remove station 19b and immediately its surface that has adhesive agent from printed medium removed at barrier liner.At station 17 place's working pressures printed medium 15 ' and matrix 20 are stacked together, as shown by arrow B, thereby with marking clip between reflecting surface 22 and transparent material layer 2.This adhesive agent is a pressure-sensitive, that is to say that it bonds together two parts 15 ' and 20 by the pressure effect.A kind of suitable acroleic acid binding agent is the S2001 that is provided by MACtac Europe SA.Barrier liner can have cross-perforating, and its cross-perforating 4 with medium 1 ' is corresponding.

With the forward position of the section of printing first with have a segment base body 20 closed contacts of reflecting surface 22.Before or after the section that will print is stacked on the matrix 20 fully, perforation is fractureed, so that independent Identifiaction plates 40 to be provided.

In a kind of interchangeable structure, medium 1 ' with foregoing moulding transparent material layer 2 and the opaque barrier liner 3 of cooresponding moulding does not sketch the contours by cross-perforating 4, its cathetus 4 is the estimating position of line of cut or perforated lines, and independent section obtains by this line of cut or perforated lines.As mentioned above, printer 5 passes the path of photosensor 8 along with light monitoring media 1 ' and starts.On the print surface of transparent material layer 2, apply adhesive agent, apply additional barrier liner subsequently again, avoid polluting with the protection adhesive agent.

So the medium 15 ' that forms can be cut into the section of matrix size at line of cut 4 places of expection, and this carried out before or after additional barrier liner is removed at station 19b place, and the latter is more preferably.

Matrix 20 can form in many ways.First kind of mode is simple ABS injection mo(u)lding or extrusion forming, perhaps cuts out down the matrix of required form and size from a material layer, then by the stacked mode reflective film that bonds on an one first type surface.Suitable reflective film material is by Minnesota, Mining and Manufacturing Company (3M) of St.Pauls, the Diamond Grade and Engineer Grade reflective film that Minnesota, USA provide, but also can use other materials.Usually to be that surface forming with matrix 20 gets more coarse for more useful way, is bonded on it so that help reflex-reflective material.

Other operable reflective material layers form the reflex-reflective material layer composition that two first type surfaces all are applied with adhesive agent, and this adhesive agent is covered by division board.After removing nethermost division board, be bonded on the segment base body of suitable size by stacked bottom with the reflective material layer estimated.Then, the matrix that is applied with reflective material layer is in store for future use, perhaps promptly uses for thirty years of age, thereby expose the reflecting surface of bonded dose of covering by removing uppermost division board.Print surface with transparent panel is stacked on it then.This combinations of reflections thing does not need adhesive agent to apply station 16 or apply adhesive agent on reflecting surface.

As a kind of selection, be used for the ABS of injection moulding matrix 20 or one section reflex-reflective material of the matrix size that other plastic material have therewith injection moulding.

In order to realize this injection moulding, the leading edge of one section reflex-reflective material plate is placed, is dragged into or draws in the mould, and its clamping is on the throne.The part of mould is leaned against on this plate.Simultaneously, a first type surface of reflex-reflective material contacts with the top of mould, provides a cavity between other first type surfaces of reflex-reflective material and mold bottom.Plastic material such as ABS are injected in this cavity.When mould during by tight closure, reflex-reflective material is bonded on the matrix 20.The size of this reflex-reflective material section can equate with mould, and is perhaps bigger than mould.If then need cut away redundance than mould is big.

This method does not need to make matrix section 20 to have rough surface and reflective material layer is stacked on it, thereby has reduced cost.

With reference to Fig. 5, shown the section drawing of the label of making according to said method 40.Matrix 20 is the one section plastic material such as the ABS of injection mo(u)lding, and its inside has a plurality of reflecting glass pearls 21, and these beaded glasses 21 provide reflecting surface 22.Plastic transparent material layer 2 is bonded on the matrix 20, is printed with mark 43 above it.

Matrix 20 as shown in Figure 5 forms by the injection-moulded plastic material, is distributed with reflecting body in plastic material, and for example diameter reaches 15 microns glass bead.When forcing plastic material to enter in the model, glass bead can be because gravity precipitate (if their density is greater than words of the density of liquid plastic material) or to surface come-up (as if their density less than words of the density of liquid plastic material).As selection, can carry out the selectivity drying by microwave pearl 21 is preferably moved towards a surface.The additive method that obtains this result is known for a person skilled in the art.

Fig. 6 demonstrates the label 40 ' with matrix 20 ', and the transparent material layer 2 that is printed with mark 43 above is coupled.In this matrix 20 ', reflection grain 21 is uniformly distributed in its whole thickness basically.The quantity of particle 21 can be greater than shown quantity in the per unit volume, with the required reflective characteristic of the label 50 that obtains to finish.

In this case, do not allow particle 21 precipitation or float to the surface.Perhaps, particle 21 in the plastic material 20 ' is very concentrated, to such an extent as to can not be preferably to the particular surface precipitation, perhaps their density is substantially equal to the density of liquid plastic material, thereby prevents that a kind of composition from producing any preferred precipitation with respect to other compositions.

In case transparent material layer 2 is applied to matrix 20, on the 20 ' surface, it just has reflective characteristic.The absolute reflective characteristic of beaded glass and other reflection grains is not as special reflex-reflective material height, but because the thickness of transparent material layer 2 is compared with the acrylate plate (considering in some application of the prior art) that uses 3.2 millimeters thick is so thin, so label 40,40 ' reflective characteristic is enough to satisfy desired standard.

Fig. 7 has shown the Identifiaction plates 40a that can use said method to make.The base portion 44 of this label 40a has witness marking 43.

Fig. 8 has shown the label 40b that has extendible portion 41 on the base of needs, and this extendible portion 41 is used for the 3rd mark 42.First mark 43 is appreciiables.The second mark (not shown) can be printed onto on the transparent material layer 2, to protrude in the main body 44 ' of label 40b.The 3rd mark 42 can comprise advertisement or other personal informations, and can " off-line " print or print simultaneously or printing continuously behind first mark 43 with first mark 43.The white or the back layer of other colors can be applied on the matrix 20 and cross extendible portion 41, so that provide background for the 3rd mark 42.In other embodiments, the color of printing the 3rd mark 42 is distinguishable for matrix 20.Transparent material layer 2 can be applied on the whole extendible portion 41, perhaps is applied on the part of extendible portion 41, perhaps is not applied on the extendible portion 41.Reflecting surface 22 can extend to a part or all extendible portions 41.

Clearly, using a computer the printer of controlling 5 can be with different label print on the successive segments of medium 1,1 '.For vehicle identification plate, can on section in succession, print two groups of identical marks, one group is used for the fwd label, and one group of label that is used for the back prints other two groups of identical marks then, or the like.

Printable media 1,1 ' can print general information in advance with as second mark.This information can be represented producer, supplier or other personal informations, security information, or the like.This producer that transfers in a small amount of week of printing in advance by Identifiaction plates provides alerting ability greatly, because any general information is pre-printed, thereby can use printer 5 to come the special primary marking 43 of printshop need simply, as license number.Therefore, producer can have preprinted printable media 1,1 ', thereby republishes primary marking 43 when the needs identifying plate shines 40.

Employing process control printing as using the printer of Astro-med QLS 4100 series, can further be simplified the manufacturing and the cost-cutting of licence plate.

A requirement of above-mentioned British Standard, Automobile Series is the yellow of the material of vehicle back number label for certain colourity.In Greece, for example, a kind of background colour of label is necessary for blueness.The also requirement in Europe when when this country sails European other countries into, will have the sign of area country and European flag (EU Council Regulation 2411/98[3]) on the vehicle identification plate.Because country's sign is to be printed onto on the reflective material layer traditionally, so increased cost.In addition, it is relatively expensive to meet the reflex-reflective material of the yellow of required standard and other colors.

Use the process control of printer 5, semi-translucent colour-coded material can be printed onto on the transparent material layer 2.And, " Europe " flag of blueness and primary marking 43 and any second and the 3rd mark 42 can be printed onto on transparent material layer 2 and the national mark.Printer 5 with primary marking 43, second and any the 3rd mark 42 in each and colored trnaslucent materials be printed onto on the transparent material layer 2 from special use printing colour band 7.Because to the accurate Calculation machine control of print head 6, any marker material all need not overlapping.

Clearly, for example in Britain,, need to adopt two pipeline production lines traditionally if the number label (yellow) of vehicle back and fwd number label (white) are different colours.A kind of selection is coloured label of alternately making described yellow and white on a manufacturing line.Adopt this method, if in a pair of label one be damaged, if two whites or yellow coloured matrix are placed in the manufacturing line mistakenly in other words, then can have problems.Therefore, by the process control printing, because the quantity of needed manufacturing line reduces, tank farm stock can reduce.

The colored translucent material that is applied on the transparent material layer 2 allows to use white reflecting surface 22, and the colored translucent marker material adds the color of needs in the label of formation like this to.This white reflection material layer is obviously than the yellow of desired certain colourity and the material cheapness of other colors.The thickness that is applied to the coloured marker material on the transparent material layer 2 is designed to its only reflectivity properties of Min. ground interference reflex-reflective material.The reflecting surface that this method also can be utilized for the label 40,40 ' in Fig. 3 and 4 provides needed color.

Fig. 9 has shown the details of printer 5, and it has thermal printer head 6 and colour band 7 '.When the printable media 1,1 ' with transparent material layer 2 and barrier liner 3 during through colour band 7 ', start print head 6, by applying heat and pressure some look waxes and/or pigmentary resin on the colour band 7 ' are transferred on the transparent material layer 2.

Particular color such as black and redness will trend towards being applied on the transparent material layer 2, thereby make that can't see through described mark sees reflecting surface 22.For these colors, traditional individual layer colour band 7 provides by sheet metal and transfers on the transparent material layer 2 by the heat and the pressure effect of print head 6, and wherein individual layer wax and/or the resin in the individual layer colour band 7 is painted by marker material.

But, under some situation, when using some color, when transparent material layer 2 is bonded on the reflecting surface 22, must guarantee the mark sufficiently clear of so printing and as seen.In this case, can provide a kind of compound colour band 7 '.

Compound colour band 7 ' comprises double-deck wax and/or resin, and the ground floor 72 that will contact with transparent material layer 2 is needed color, and 71 of the second layers of the reflecting surface 22 of the matrix 20 of close finished product label 40,40 ' are opaque, are generally white.The use of individual layer and compound colour band 7 ' can guarantee first, any second and/or any the 3rd mark 42,43rd that print, appreciiable, and to guarantee that the reflecting surfaces 22 below the mark 42,43 in use can not see through and be revealed.

Another advantage of injection moulding matrix 20,20 ' is, can form cavity in its rear surface.The size of this cavity and shape can be designed to be able to hold electronics package.This device can be inductor, signal projector or transponder.An example is the transponder that is used for the traffic monitoring on the network of highways (for example automatic toll collection highway).As selection, can settle the vehicle safety device therein, so that stealing vehicle number label is given a warning.The device main frame can be placed in this cavity.In the label of prior art, simple matrix is applied on the reflex-reflective material, and mark then is sandwiched between them, and so then can not provide this cavity, all can block a part of reflex-reflective material because any device is arranged in this cavity.

Figure 10 has shown a specific implementations of the licence plate of making according to said method 100.The licence plate 100 that has mark 43 is designed to show steals structure, and has the first 102 between two second portions 103.Can't see the detailed structure of part 102,103 from the front of label 100, as shown in figure 10.

Figure 11 is the lateral plan of label 100.Label 100 is formed by elongated ABS matrix 20, and matrix 20 has relative first and second 106,107.

First 106 is reflecting surface, is applied with reflective material layer above or inside has reflection grain.The transparent material layer 2 that is printed with mark 43 above is bonded on the reflecting surface 106.

Be formed with line of weakness 110 on second 107 of matrix 20, these line of weakness 110 form by the mode of cutting or injection channel or groove in matrix 20.

As shown in figure 12, line 110 extends on second 107 Width.

Adhesive pad 111 is bonded on the face 107, and each pad 111 is covered by an isolation layer well known in the prior art.Pad 111 is present in each side of line 110.Pad 111 does not extend on the whole width of face 107.

For label 100 is assembled on the vehicle, isolation layer need be removed from each adhesive pad 111, then label is pressed onto on the vehicle.Pad comprises the contact adhesive agent, so that label 100 is bonded on the vehicle.

If matrix 20 forms by injection mo(u)lding, then line 100 forms in injection moulding process.Perhaps, line 100 also can mill out from matrix 20.

The thief that attempt is taken off label 100 from the vehicle or other bad persons need prize label 100 from vehicle.The easiest place under fire is the end of label 100.It is main taking off adhesive pad 111 needed power from vehicle bumper, along line of weakness 110 the label 100 needed power that fractures then is much smaller.Therefore, if want to prize label 100 down from vehicle, label can break along line of weakness 110.In case break, layering will appear in the transparent material layer 2 at close break line place, and then damages the appearance of label 100, thereby guarantees that label 100 can not re-use, as shown in figure 13.

In addition, if someone wants the transparent material layer 2 that has mark 43 is taken off from label 100, binding power between the surface 106 of transparent material layer 2 and label 100 can make transparent material layer 2 stretch in the process that is removed, thereby can destroy the outward appearance of mark 43 and transparent material layer 2.

As further decoration, can form electric contacts along line of weakness 110, thereby when from vehicle label 100 being taken off, contact open and alarm are sounded.This contact can be connected in warning system direct by lead and on the vehicle dial plate.

Label 100 is seen as " common " licence plate from the front, the thief who therefore steals vehicle identification plate can not throw doubt upon always, just knows when damaging in hand up to can not intactly label 100 being taken off.

Vehicle has, and safe, the antitheft or apparent licence plate of stealing is good, and these licence plates can be used for military affairs, police, foreign service, public security car or the like.But clearly, any vehicle can both be stolen benefit the label 100 from this showing.

In said method, used heat transfer printer.Figure 14 demonstrates the ink-jet printer 5 ' with ink-spraying-head 67, and it uses a UV cure lamp 66 dry printing ink that so apply, thereby can replace heat transfer printer to use.Can after station 16 places apply adhesive agent, an isolation layer be set and apply station.

Under the prerequisite that does not deviate from the scope of the invention, can make variations and modifications to this equipment.For example, can use signal processor 11 to control each stage in this method: conveying, printing, stacked, separately perforation, or the like.Light beam generator and detector system can be duplex systems, and wherein Shu Chu light beam is by other detector persistent surveillance, and the signal that treater 11 uses is the ratio of two kinds of detection signals, thus the strength fluctuation of normalization light beam.Light beam generator can be simple light source, for example the small bulb in the fluorescent tube, diode or other suitable radiants that can be weakened by barrier liner 3.Be used to guarantee that the stacked adhesive agent between printed medium 15 and the matrix 20 also can be applied to the reflecting surface 22 of matrix 20.

Method disclosed herein can be used in makes vehicle identification plate and other signal-warning labels, bearing mark, chamber indicating device, or the like.Fragile part can be used for guaranteeing that any mark can't not be damaged or not obvious remove from its fixed position.
