Description

Self inking embossing system

The present invention relates to a kind of self inking embossing system.It also relates to a kind of pattern is protruded up and down and is impressed into the imprinting apparatus that is stamped on the material.

Each coining plate has two zones at least in this device.In at least one zone, the image of required impression is stamped on this regional paper positively.On other zone, the image of required impression is by protruding on this regional paper negatively.

By this explanation and claims, following term will adopt the definition of broad sense given below:

(a) " sheet material " comprises paper, plastic paper, fabric, card, cardboard, plastic plate, metal forming, laminated sheet or analog;

(b) " positive impression ", downward (promptly towards following) impresses from the sheet material plane to refer to required image;

(c) " negative impression ", refer to required image from the sheet material plane (promptly towards top) impression upwards;

(d) " sun version " or " sun version part " refers to have at least version or the part version of place protuberance on sheet material;

(e) " cloudy version " or " cloudy version part ", the version or the part version of the sheet material that refers to have at least a place to be embossed into chase or groove;

(f) " mark " refers to letter; Speech; Signature; Logos; Seal; Pattern; Illustrative image or analog and/or above-mentioned two or more combination.

At present, improve the confidentiality requirement of commerciality and legal document constantly in increase.

Major company will handle millions of dollar every day, unprincipled fellow's metal system of also always having an opportunity to cheat, and check or other marketable securities may be stolen, and forge signature on it (or other according to), or forge whole file.

The company that has uses signing machine to imitate signature on check, but this is very easy forgery.

Some this class machine is printed on signature or be stamped on the paper of check.Though antifalsification is improved, the signature quality is very poor.

With regard to document quality, legal document for example, the certificate of registration and bond can not be gone up China ink and impression to file simultaneously, and obtain high-quality effect.In fact printing (going up China ink) is a first step, is embossed to second step, and the two position will be aligned simultaneously need be careful especially, for example prints compound seal.

An object of the present invention is to provide and a kind ofly make visual each several part be stamped in imprinting apparatus on the sheet material by negative and positive.

Another purpose provides a kind of imprinting apparatus that mark is printed simultaneously and is stamped on the sheet material.

A further purpose provides a kind of imprinting apparatus, " fingerprint of mechanism " that its resulting impression (and printing) provides one very difficult on sheet material (if not impossible) to forge.

Further purpose provides a kind of imprinting apparatus, and " fingerprint " of computer identification (or really knowing) is arranged on its sheet material.

Further purpose provides a kind of imprinting apparatus, and whether its " fingerprint " can detect by scanning and forge or alter.

Can obviously see other purpose in the following accompanying drawing.

One aspect of the present invention provides at least one mark is stamped in a kind of imprinting apparatus on the sheet material, and it comprises:

First coining plate;

Second coining plate; Wherein:

First coining plate comprises at least one positive plates part and at least one female plate part;

Second coining plate comprises to its additional one a corresponding negative electrode added edition part and a corresponding anode added edition part;

Arrange that like this at least a portion mark is stamped on the sheet material by the positive, another part mark is impressed by feminine gender at least simultaneously.

The mark of positive impression partial can be whole or partly centered on by negative impression partial, perhaps opposite.

Printing ink can be added to the positive part of at least one version, make this mark can be printed on simultaneously and be stamped on the sheet material, also can between one (or two) version and sheet material, put into the China ink band, mark can be printed and be stamped on the sheet material simultaneously.

Preferably, the height of the convex ridge of anode part or projection equals the degree of depth of its complemental groove on the cathode portion or groove.

Preferably, when version was stacked, the distance between top to the bottom of its complimentary recess or groove of each convex ridge or projection was greater than the thickness of sheet material, or was with the thickness of addition greater than sheet material and printing ink or China ink.This distance is greater than sheet thickness, or sheet material and China ink band combined thicknesses, for well, is preferably 0.03-0.05mm from 0.03-0.1mm.

Preferably, the width of depression or groove surpasses the width of its complementary convex ridge or projection.

Preferably, stand out more preferably greater than 0.08-0.15mm, but is not more than 0.4mm just greater than the twice of this zone sheet thickness or sheet material and black tape thickness addition.

Preferably, the distance of the sidewall of complementary ridge that the sidewall of depression is extremely adjacent or projection is greater than (0.075mm is better), preferably 0.04-0.075mm more than the thickness 0.2mm of sheet material or sheet material and the addition of China ink band.

Preferably, each edition is bonded in plastics by one deck photosensitive polymer or nylon membrane or metallic plate (can be positioned on the marking press) is made a mouthful ridge, projection, and depression or groove are formed on the thin layer of each edition.

Preferably, the positive impression partial of mark appears on the sheet stock material with solid line basically.

Preferably, the negative impression partial of mark appears on the sheet material as the shadow line in abutting connection with (projection) part.

Preferably, Ban neutral fraction (transition of ridge or protruding and depression or the groove) relation that maintenance separates when impression is in case black on this neutral fraction.

Preferably, on version, the sidewall of ridge or projection and depression or groove is perpendicular to this neutral fraction, but also tiltable.

A second aspect of the present invention is that the above-mentioned impression system of a kind of usefulness impresses its step of method of a mark on sheet material:

(a) sheet material is placed between first and second editions;

(b) send first and second editions relatively to, align stacked the cooperation with the corresponding complementary negative and positive version part of second edition with negative version part, mark while negative and positive are stamped on the sheet material up to the positive of front page;

(c) separately two editions, the sheet material that has impressed can be taken out.

In order to print simultaneously and to impress, in step (a) before, can add at least one edition positive part China ink one also can be before version is overlapping among the step (a) the China ink band be placed sheet material with edition or between two editions.

For fully understanding the present invention, preferred embodiment will be described with reference to the drawings, wherein:

Fig. 1 is an impression and the plane that is imprinted on the mark on a piece of paper or the similar sheet material;

Fig. 2 is the profile along the 2-2 line of Fig. 1;

Fig. 3 is the plane (for ease of understanding, with reverse or mirror to illustrating) of negative of the mark of an imprinted pattern 1;

Fig. 4 is along the base plate of the 4-4 line of Fig. 3 and the profile of complementary ceiling;

Fig. 5 is a profile that amplifies, and paper or similar sheet material is shown goes up China ink and impression simultaneously;

Fig. 6 one separates the cutaway view of alternative embodiment of version;

Fig. 7 one goes up the sectional view of alternative embodiment of China ink and impression simultaneously on paper or similar sheet material.

With reference to figure 1, comprise with oblique line/striped 11 being the mark 10 of " HLE " of background, be stamped and be imprinted on paper 20 or the similar material.

The central area 12 of mark 10 is promptly protruded to the paper plane below by positive impression, and mark is essentially solid line or thin outline line is seen Fig. 2.By negative impression, promptly protrude above paper plane the borderline region 13 look central areas 12 of mark 10, and the outline line that this mark conduct centers on the bossing of the scraps of paper 20 occurs.

With reference to figure 3 and Fig. 4, mark 10 one have one fixing on the marking press of platen 31 and a movable platen 32 down, use a pair of complementary coining plate to make.

Ceiling 40 is with negative 50 one deck photosensitive polymer 41,51 on a metal base plate, and can move on the corresponding platen 31,32 of marking press 30 or nip drum.

Each edition 40,50 have one corresponding edition part 43,53 and one aligns complementary negative version part 44,54, positive version 43, the height of 53 back or projection 60 is substantially equal to negative version 44, the degree of depth of depression on 54 or groove 61, but platen 31,32 control versions 40,50 relative motion makes back or projection 60 and it aligns complementary depression or the distance between groove is not less than the scraps of paper and China ink is with 80 thickness sums.

(be represented by dotted lines in Fig. 4) when negative 50 is sent to, mark 10 impresses out to negative and positive simultaneously on the paper of respective regions 12,13.

For making mark 10 China ink and impression on carrying out on the paper 20 simultaneously, can be before paper being put into 40,50 of versions, will not drip China ink by an ink roller 70 and be added on the back or projection 60 of positive part 43 of ceiling 40.Because it is when version 40,50 was put together, the distance between its neutral fraction was not less than the thickness of paper 20, only black on the positive imprinting area 12 of mark.

(see figure 5) among the embodiment of China ink and impression on another while is on paper, before impression, one China ink band 80(be can be one or more color inks on the carrier for example red/green/orchid) be placed on the scraps of paper 20, also can be by suitable the infeeding by ceiling 40 on the marking press 30 for the guiding systems (not shown).

As shown in Figure 5, the height of back 60 and depression 61 deep equality, but will control the motion of negative 50, make neutral fraction 45,55 be not pressed in China ink be with 80 with the scraps of paper 20 on, thereby do not go up China ink in these zones.(can control as shown in Figure 6) by the spacer block 34 of 40,50 of versions.

When being preferably in impression, control the relative motion of version 40,50 by the braking action of the scraps of paper 20.

The width of groove 61, surpass the width of its corresponding back 60 and the scraps of paper 20 add China ink should be with the difference of the twice of 80 thickness less than 0.4mm, that is, a sidewall of groove 61 is to the distance of the sidewall of adjacent back 60, and it is better with the 0.2mm(0.15mm of 80 thickness sums with China ink to be no more than the scraps of paper 20).

Impress 12 zones (seeing Fig. 5 left side) in the positive, when back 60 entered groove 61, the scraps of paper 20 on the groove 61 were subjected to stretch (but the peripheral region is unaffected).Pressure between the sidewall of back 60 and groove 61 makes thin outline line inking and since the bottom of back 60 tops and groove 61 not paper-pressing sheet 20 or China ink be with 80, go up black minimum therebetween.The wedge angle 60A of back 60 has guaranteed the boundary line of inking well.

Impress 13 zones (seeing Fig. 5 right side) in feminine gender, the scraps of paper 20 form " shade " or the boundary line around it in the outside inking of projection impression, and the scraps of paper extend around the angle 61A of the recessed limit 61 of female plate part 44,54.

The scraps of paper 20 and China ink be with 80 and version 40,50 between friction, the relative motion of control version does not contact neutral fraction.Change the width of depression 61 and the width of corresponding back 60, selectively regulate brake force, with the relative motion of control version 40,50 in impression and inking step.Should before the version contact, regulate braking effect.If paper is too light, two editions will contact fully, thus each regional inking.(increase paper thickness and for example will increase brake weight, reduce the relative motion that back 60 enters depression 61 from 75gsm to 80gsm.) inherent strength of paper is big more, its trend that is pushed to recess walls is more little, thereby has increased brake force.

Version 40,50 operation depends on test and the error of impression with paper, the degree of depth of impression by the weight with paper (being GSM) and be added on pressure on the version, and the relative distance between back and the recess walls decides.The pressure that is added on the version increases, and depth of indentation just increases.Usually, each impresses the pressure of function control and regulation impression.

Shown in Figure 7, the relative motion of the controlled plate-making 40,50 of skew wall is provided on back 60 and depression 61, skew wall produces the effect of wedge between version.

This device be applicable in following sheet material or carry out negative and positive impressions thereon simultaneously and on China ink, this sheet material comprises:

A) paper;

B) plastic paper;

C) fabric;

D) card;

E) cardboard;

F) plastic sheet;

G) metal forming; Or

H) one deck, two layers or multilayer above-mentioned material.

Potential application comprises;

A) printing credit document signature or credit ticket, bond, or other have the valency business vouchers;

B) printing scrip certificate;

C) think forgery and/or need computer to discern on the file of (by scanning) add a cover company or legal person's chapter the bad person.

Because negative and positive impression and upward black in the time of mark, the possibility of forgery effectively descends.

Be to produce ideal effect, back or projection and depression or groove should be on version 40,50 Accurate Shaping, version 40,50 should accurately align in use.

Version 40, the sheet material of 50 impressions produces the mechanical fingerprint of an independent thing, because version 40,50 is home built, and its tolerance is so little, during plate-making, any unalterable minor variations all might occur, when under pressure condition, when promptly making an independent thing under the time critical environment, visible difference appears just on version.

Therefore, if be that a stamped signature is done twice plate-making, the different version of two covers will be obtained. Version 40,50 is made by photosensitive polymer, and hand washing produces required result under the crash time condition.The crash time condition is suitable for, because if version can not be finished in mutually in the very short crash time, its profile is with collapses down.(owing to adopt braking technology to stop the motion of version 40,50, any nuance on the wall of depression or back all presents the visible surface of mark-showing as pressure on the stamped signature and be added on the difference of the quantity of ink on the paper.Therefore, the operator makes the tolerance of the percentage millimeter magnitude that can not copy master definitely with such critical speed operation.

Be stamped in the last three-dimensional machinery texture on the sheet material 20, can sweep computer by existing scanning device, and by using similar system at the U.S. developed intersection proofreader fingerprint to read and discriminate.Yet, in the case, reading in paper 20 front and back simultaneously, two scanned pictures need fully relevant with the correct image that provides.Back texture by make its by on the firm ink roller by producing, at this moment printing ink can only be added on the bossing of paper (people's fingerprint is equally by referring to that bossing on the skin obtains).

Then, can scan this texture, must align and produce two-sided texture with the not coplanar that accurately provides a positive mark paper relatively by the finger scan processor, or the different texture of same stamped signature.This technology improves the check disposal ability of bank greatly, and offers bank one and make it produce at a high speed the stamped signature identifying device of high precision.This extremely accurately is difficult to duplicate, because its two sides has nothing in common with each other, each face need align just fully can obtain suitable certificate.

The personnel that this specialty is familiar with are easy to understand, the invention provides a high-quality, the impression and the black printing device of safety.

Within the scope of the present invention, can be to described and change with the embodiment of description of drawings.
