Abstract
By using means of granular material absorbing ink, printing ink can with high fidelity be transferred on the plastic sheeting.For purpose of safety can be superimposed together this plastic sheeting and another plastic sheeting, produce safe file.Just flow or cross the file that certain hour flows, can change humidity and the temperature when superimposed in order to produce.
Description
The present invention relates to typography, though be not only to be used for, mainly is to be used for plastic printing, the file that is difficult to duplicate with production; The method that the invention still further relates to the structure of finished product file and intermediate products and produce them.
Along with the raising of replica technology, file is easy to be replicated, therefore, file be forged into a subject matter.The scope that is forged file is very big, for example: the card volume, paper money ticket and membership card etc., this suffices to show that forging and duplicating is to be difficult to control.
Because paper document is easy to shabby, so a kind of plastic document of necessary production, for example this patent is described.But up to the present, all trial all can not be satisfied user and operator's demand well.
A problem of printing on plastic sheeting is the pigment problem, and at first, pigment can be used solution, and for example acetone is washed off from plastic sheeting, and this just makes file change arbitrarily.In order to address this problem, people once attempted covering layer of plastic film again printing ink were sealed on plastic sheeting.Yet this has two obvious problems.At first, it is found that plastics, for example polyvinyl chloride or polyester or polyethylene film are speckling with printing ink or the dyestuff place can not fully be bonded together.In addition, people also find directly to print on plastics and then cover one deck plastics printing ink or dyestuff are sealed, and its effect is also unsatisfactory, because printing ink or dyestuff meeting horse back or mobile in a period of time cause slur.This problem can overcome by drying with high-power infrared ray or ultraviolet ray, but this process is not only time-consuming but also expensive.
The objective of the invention is to improve existing product and design an improved method.The present invention is used to provide does not flow or the product of controllable flow speed in essence.
Characteristics can provide a process of printing on plastic sheeting according to an aspect of the present invention, and this process comprises:
(preferably inorganic matter is imprinted on the film pigment that will be made of the grain raw material, and this raw material is bonding by binding and negative, and can discharge.
In covering layer of plastic film on the printed layers pigment is transferred on the plastic sheeting, and added certain heat to it.
Negative is taken away, and it is sticked together with second plastic sheeting best, so just pigment has been encapsulated in the middle of the plastic sheeting.
Manufacturing documentation can be avoided flowing of printing ink like this, and, if necessary, second layer plastic sheeting and the plastic sheeting that is printed on literal can be sticked together, even also can be bonding in the place of dyeing.This may be to be bonded at polyethylene because be impregnated with the printing ink of particulate material.In addition, by bonding second layer film, make and revise the difficulty or impossible that becomes.Because printing ink has been enclosed in the plastics.
Plastic sheeting preferably polyester film adds layer of polyethylene, and for example at Morane(Banbury, U.K.) Mai Mai merchant is named as the film of Morafast.
Other plastics, for example polyvinyl chloride also can be used, but ink marks can be removed with acetone.Yet poly adhesion characteristic makes it more desirable, and after bonding, acetone is to ink marks also not influence, and like this, printing ink or dyestuff will forward on the polyethylene film when use has the polyester of polyethylene film.
Pigment can be any printing ink or dyestuff.But preferably use diethylene glycol (DEG) printing ink, the grain dyestuff is done pigment.
These printing ink are most popular with poly the time, because they are cheap and printing effect good.
Grain matter or colloid raw material be silica, sand, silicon, clay or chalk preferably.Wherein silica is best, although above-mentioned several raw material can, silica is all better than other raw material.
Preferably the outside with particle is stained with latex (being exactly polyethylene) or starch.
Though other material also can be used, negative preferably adopts the dense paper that surpasses every square metre of 80gms, in order to avoid tear to shreds when paper is taken away.It is very low that paper does not preferably contain crude fibre or content.Parchment preferably in sulfuric acid infiltrate wash then.
Pigment or printing ink can be random.Suitable machine comprises, computer-controlled printer, and the type matrix printing machine, laser printer, ink jet printer or version seal machine etc., wherein ink jet printer is best.
Contacting and to transfer to printing ink on the plastic sheeting by plastic sheeting and grain raw material surface.Raw material has been printed on the surface and has accepted heating.This can finish by double-layer films is passed from standard lamination device, and required temperature is by the thickness decision of used plastics and film.
Then will be normally the negative of papery peel off, its plastic sheeting good with having absorbed ink printing is separated, if necessary also can dash or scrape by water.Yin Shua plastic sheeting is washed printing ink off with solution than the plastics of traditional printing are more difficult like this.
As noted, printed plastic sheeting can also be bonded together with an other plastic sheeting printing ink or dyestuff are sealed, and makes file energy " false proof ".This point is particularly important to classified papers.
According to a further aspect in the invention, can also provide a kind of plastic sheeting with silica layer.
The volume of great majority or whole particles is preferably from 5 microns to 0.006 micron of diameters, if better to 0.006 micron from 1 micron.
The volume of particle can determine that determine which particle can pass through, which cannot pass through by a series of screenings.
Plastic sheeting can be any the making in the above-mentioned plastics, but preferably polyester or polyethylene sheets.
Stratum granulosum is preferably having the one side of polyethylene sheets.
Do not wash and bonded, the raising that it is believed that printing quality theoretically derives from pigment and has arrived on the plastic sheeting with " dried state " transfer of granules.
The silicas of the different amounts of packing into can produce that dissimilar files-every square metre 4~8 gram (best 5~7g/m packs into
2) can produce transparent file, 8~20 gram/m pack into
2Produce opaque file.
There is not mobile file fully in order to produce, when taking down negative, grain matter or colloid raw material had better not surpass in 40% the air in humidity expose a period of time (not above 20 minutes), necessaryly then when temperature is higher than 350 °F second block of plastic sheeting and first film is forced together.This is applicable to silica, plastics and paper, and it is better than the method for mobile file of used production.
Readable in order to produce beginning, and the file that flows after a period of time, above-mentioned film should be exposed to humidity and be higher than in 40% the air (that is 40~80%), and first, plastic sheeting should apply certain water smoke.This one deck does not just need to have absorbed any moisture content from air, the second layer then when temperature is lower than 350 °F and ground floor superimposed.
After printing on the plastics, can adopt additional step, the type according to producing file improves its security.
For the lamination file, as the yarn ticket, ticket etc. are so produce the marking of a kind of similar " watermark ".The following marking of mentioning can be produced as follows:
A piece of paper preferably weight surpasses 80gms, and the weight low spot also can be used, and the surface of paper is with the silica granule layer, and there is the pattern by the method belling of metal pattern or other belling paper on the surface of paper.Trace preferably is imprinted on and makes the face pressurized on the silica film, though this method is passable, efficient is lower than other method.Then the paper particle of belling is placed downwards on first block of plastic sheeting, again this two layers of paper is passed from the lamination device, the paper of printing ink from the band film is shifted as described above.Then negative is taken off, just can see trace after second block of plastic sheeting and first are sticked together, this trace does not contain ink marks, and can not optionally remove or reduce in final products.
Can characteristics of the present invention be described out by an example and following detailed description now.
Produce the plastic printing file that contains " watermark ", can carry out according to the following steps:
A piece of paper comprises the parchment negative and silica layer is arranged in the above, and the pattern of printing is arranged on the silica layer.Used printing ink and dyestuff are standard printing dyestuffs, and pattern is the printer that computerizeds control or the printing of other method.
In another place of paper, preferably there is not the place of lettering, with the metal pattern belling paper that protrudes pattern is arranged, the surface of band film is also protruded.
Then printing paper is built, for example used the polyester plastics paper of 100 micron thickness, plastic paper has at least one side to have 16 microns polyethylene film, so just makes polyethylene film relative with silica film on the printing paper.Two films are heated to uniform temperature to be melted to polyethylene to be enough to absorb printing ink.For the paper that this example provides, the temperature that needs is 32 ℃ (90)~60 ℃ (140), preferably 38 ℃ (about 100 °F).This can reach by paper is passed from the lamination device respectively.Should be noted that the characteristic that exemplifies above is not what limit.Polyester paper preferably is thicker than more than 30 microns up to 500 microns, polyethylene film preferably from 12 microns to 29 micron thickness.Added heat need be constant, to produce enough pressure the air in the middle of the paper is got rid of.
Then negative is peelled off, can be peeled generally speaking, if but very firmly sticking, also can water blend and scrape.
When paper and plastic sheeting were superimposed, the part of protruding in paper can make polyethylene be forced out.After paper is taken away, when another plastic foil and first are bonding, will stay tangible trace.The definition of the usefulness heat effects trace in the lamination process.Superimposed hot more, trace is just unclear more.Generally speaking, used lamination temperature surpasses 49 ℃ (120 °F).
When superimposed encapsulation printing ink, can be at the thing of wanting to insert in the middle of the superimposed paper other.So just can add mirror brief note or electronics stamen sheet, and be inserted in the final products.In superimposed, need silica layer is clipped in the middle of the two layers of polyethylene layer.
Below result in the table 1 shown how to use the file that the present invention produces different flowing times.
What example was used in the table is parchment and the diethylene glycol (DEG) that contains food dye.Printing ink obtains like this, trade mark (is come from the Clayton ∞ Jowett Runcom of Co., Ltd for the yellow food dye of " GOLD SEAL ", England) evaporation makes its volume reduce 75%, and surplus solution is mixed with diethylene glycol (DEG), produces the final printing ink that contains the 20%u/v glycol.On paper with 10g/m
2China ink one deck volume of packing into be 0.010 micron silica layer, stamp dyestuff then.Again printed layers is placed on the plastic sheeting towards polyester (150 micron thickness) and polyethylene (16 particulates are thick), and temperature is heated to is enough to make printed layers can transfer on the polyethylene layer of plastic sheeting, then parchment is taken off.The plastic sheeting and the printed layers of gained are gone up given temperature and time exposure a little while by table.By given temperature that second layer plastic sheeting and ground floor is superimposed at last, printing ink used time that begins to flow is definite and provided in table by inspection repeatedly.
The printing ink of ink jet printer spray can cause flowing, and after removing negative, silica layer will be exposed in the air of 40% humidity at least, and superimposed final temperature will be lower than 177 ℃ (350 °F).
Yellow, peony and blue food dye can have been bought, and its trade mark is " GOLD SEAL ", and these dyestuffs can constitute the printing ink (50% of a vaporized dye volume, rather than 75%) of aforementioned ink jet printer.By proper proportion these dyestuffs are mixed, can obtain the shades of colour that needs.
Table 1
In some occasion, be necessary to make printing ink after after a while, flowing.For example, ticket and card are thought effective within a certain period of time, can represent that the time limit is full with the mobile of printing ink, by the variation of humidity and last lamination temperature, adjust the time that begins to flow.
By the suitable variation of these parameters, can produce and usually behind some months, begin the card (seeing example 2) that flows.Then, sting and tear card silica is exposed in the air, cause the acceleration of flowing.These characteristics can be used on the consumer goods of tape label.Label can be made of a weak line or weakness, weak line in succession one the mark bar, by the mark bar label is bonded on the consumer goods.After label line a little less than the mark bar upper edge is torn, silica is exposed quicken to flow.
Even label is bonded on the clothes again, flow and still can take place, this is an advantage, can point out the storekeeper to avoid being deceived when the label of the consumer goods is taken off away.After label is stung, will absorb moisture content for clothes,, show that then clothes only " tries " mistake on if label has slight flowing at the position of piercing through from health.If clothes was worn more than two hours, whole label will flow (supposing that label is 1 " * 1 ").Yet printing ink can not overflow label, and the further improvement of this technology is about being bonded at mark bar on the label on the consumer goods by adhesive, on the mark bar movably holographic picture of one deck being arranged.If want that like this it is bad to avoid weak line or weakness to be drawn by pulling mark bar label that go to announce successful tender, label and mark bar and will be removed together, this will destroy holographic picture.The label that comprises removable holographic picture and adhesive also within the scope of the invention.
If a hologram is imprinted on the polyester and it is placed on many other printing lamination centers, will produce special effect, anyone can not be xeroxed, even can not duplicate with scanner.
Can find anything (hologram itself is transparent) of on hologram, printing, if oblique light resembles and wrapped in the hologram.And, any position of top layer, if equally as above tilt, top thing can both be seen, therefore for credit card, can stamp name at surperficial position, the account number of signature and authorized user.
Follow a kind of description and can produce multiple file, for example, aforesaid printing plastics, the material of the middle band trace that inserts printing paper or make with pressure.Because materials printed finally can be faded, add layer of material on the plastics so in concrete enforcement, be preferably in, energy uv reflectance, or the polyester of application antiultraviolet are in case be subjected to photofading.
Yet in other was implemented, the characteristics that can utilize printing ink faded by ultraviolet ray for example had printing information on the admission ticket of concert and football match, and they can be scrapped because of the light of sudden and violent doses.
In addition, can also comprise following bells and whistles:
1. can only the part of image or pattern be used hereof, another part of pattern can be held (for example at theater, football field, Wenbo you step on etc.) by the drawee at venue entrances place, the drawee can be placed on transparent ticket rapidly on the model that he holds, if pattern or image coincide then ticket can pass through.Impression of the hand also can be used, because file is transparent, differentiates so can be placed on the impression of the hand of record.
2. can add a kind of temperature-sensitive or chemical material on ticket, make the numeral of reserving in advance, pattern or image etc. displays under certain condition.
3. fibre optics can be applied on the file.They also can be employed and make:
A) by laser or other method on lamination or in the middle of the lamination corrosion one or more have the fiber of font or pattern, when use the light time,, begin to locate font or pattern is luminous at fiber from the front of blocking to the edge of card.People also find the initiating terminal measuring light flux at fiber, then can in pattern, transfer because of light at the luminous flux that the other end receives, and by the volume decision of the corrosion word that constitutes of fiber or pattern.So the luminous flux that receives can be expected and measure, if light does not reach or surpassed certain amount, card or file will be under a cloud.
B) many fibers are to arrange like this: one side light importing into from card, receive from another side, photodetector can receive and the measuring light flux from certain angle, and this angle and light enter the direction oblique of card, if do not receive correct information, then card is considered to " doubtful ".
C) fiber also can be arranged like this, and it is read as number, and with regard to the principle the same with bar code, each card has unique number or bar code.
D) also can by fiber surface light be passed to fibrous end point with fluorescent fiber.These also can be corroded and pass through photo-detector measurement.
With the credit card is example, and fiber can be placed on the whole card, can be with such as A/C number, and the information of name and so on adds the out of Memory corrosion in card, and by on motorised card reader module, relatively moving Card Reader.
Thereby utilize this method the many information that can not change can be enclosed in Ka Nei and no longer need magnetic stripe.Yet, if necessary, also magnetic stripe can be fixed or is sprayed in the goods of the present invention.
Usually, people often read transparent file facing to flat background, if file is placed under for example white background, the subtlety of file will be clear.
Do not having under the situation of suitable background, can be with such file, an additional hinge front cover on file, the people who checks card not only can see card but also can not become and change and insert by opening the capping version.
Can find: if many lithographic films are superimposed together, color can be strengthened, and can make " three-dimensional " image by the fact of example description down; Mountain and sky are imprinted on first film, and tree and shrub are imprinted on second, if as discovery, in the middle of the film that clean film insertion is printed, will produce a kind of third dimension or have reached at least to a certain extent.
Another supplemental instruction of security comprises that naked eyes can not be read but the printing of the file that available magnifying glass is read.
In another concrete enforcement, can be with tightening security property of prism effect.
In this concrete enforcement, in plastics, inserted many prisms, some is by this direction pendulum, and some presses the other direction pendulum.Read file, need to use correction card or will block to tilt certain angle.
In another concrete enforcement, can improve security by additional sheets, preferably protrude the sheet metal that word forms pattern with having.Thin slice is encapsulated in the middle of the plastic paper.Thin slice also can encapsulate with dull and stereotyped state, for resembling credit card, if be printed on circular font or numeral on the card, just can with the naked eye read easily like this.
If with China ink or the dyestuff or the lacquer of conduction, then card can be used as the part of circuit or as an ON-OFF control circuit in card, such as open bulb or open the door (as key card).
Of the present invention another concrete implement be with file partly or entirely be printed as white, this can prevent to xerox, because xerox function printing lean type.
Two kinds of methods in addition of lean type printing are:
1. from being covered with on the thick paper of 10 microns silicas, and a silica that peels is passed on the lamination cutting-outs such as figure or font or numerals, by conventional method of the present invention, last superimposed in, the printing of lean type will remain.
2. image or word or number being waited to be placed on the film when production or in the film, is exactly the film of used ground floor 5 micron thickness.After drying, second layer film pressed with roller make required pattern be higher than the ground floor film.Second layer film needs enough thickness, makes gross thickness (two layers) reach 10 microns or thicker.
2a. application process 1 can be processed the lean type pattern around the multicolour pattern, to reach the purpose that color after a period of time can flow into pattern.
Can find that " watermark " can not xerox.
If by xeroxing file of the present invention from pushing up perspective-suppose not have lean type printing and " watermark ", place it on the projecting apparatus on the top, image will be apparent on the screen.The printing of this patent is provided with a kind of can clearly being apparent on the screen, and this also can be used as safety inspection.
Can also find not overlap a bit slightly but be bonded together if be printed on identical details on the two layers of plastic, the result can produce fuzzy trace.If but will block tendency on one side, trace will align, and will read easily.
Go deep into a step thus, on all four two bar printing product not exclusively can be superimposed together with overlapping, when when the front is seen, whole printed matter seems to resemble black a card, up to removing to see card with certain angle like this.
