BOe? M ^ TOS? WñOBOCTOñ CaiqpQ Is the invention an invention generally refers to methods for document and product protection,? N & amp; d &tit? S of the invention. Many methods and products have been developed to prevent falsification of valuable documents or financial instruments such as currency Most of these documents are made through printing or lithography with high quality materials such as silk rice paper and high-contact cloth paper, - the printing of original documents can be made in black and white or in color f and if it is in colo, they can be made with color plasta, colored background and / or multicolored printing, magical processes, eopyoupes for the imaging of valuable original documents, can be blank and black or in color, and they are among others, engraved in dry and gravure. These and the other processes already mentioned in this application are very well known in the graphic arts and will not be discussed in great detail. Most of the examples above are useful for graphic arts and prevent counterfeiting. of copies with a clear moire diagram or with a "finite image" that are invisible signals in the original document or almost invisible to the naked eye. An example of the means to support? security documents, it was illustrated in the US Patent Number 5,48", 56" from Volpe. Yolpe, discover a security role that has a finite Nimagen "desired that are signals formed by continuous lines at an angle and a background image also formed of continuous lines but at an angle different from that of the signals, the signals are only visible when They are photocopied An example of the means to print a security document, illustrated in the USPatent Number 4,715,623 of Roule et al Roule et al, discovers a document that has at least two-lines of raised lines that can be vertical Uniform, uniform or curved irons are formed in a press for dry realization.These highlighted lines, however, do not register or enhance a printed color line that has passage, even though the document can be printed, Rou ee al, failure to discover that the document that has printed lines of color with a step or printed lines of color that have a step that was recorded in the engraving.

It has become imperative that additional documents be found in the document protection area for documents of value and security. In the past, - to be sure that a document is a finite image, if it were authentic, you had to photocopy the document and see in it the finite image itself. To avoid this requirement / to fetocopy to authenticate a document, there is a need for easier means to ensure the authenticity of the documents with a finite image. Obje ive to the I vention Our invention provides a solution of easier means to ensure the authenticity of a document with a finite image. Our invention is a method and a product that makes a security document resistant to counterfeiting. In one of the embodiments of the present invention, a "K" has at least a few printed color lines that have a bit where a portion of the printed lines are embossed. The enhanced part of the lines form a finite image. The finite image is visible when viewed from non-perpendicular angles relative to the document and the recorded angle. The finite image is invisible when the document is viewed from an angle perpendicular to the document or when a fooostatic image of the original document is being viewed. Therefore, it is a purpose of the present invention to provide a method if significantly improved for verifying original documents. It is a purpose of the invention to produce paper in which valuable documents can be printed allowing easy identification of an authentic paper document. These and other purposes and advantages of the present invention can be determined in the following description of preferred embodiments according to the invention and the accompanying drawings and claims. Brief Desoripeiop gives the Drawings Figure i is an example of the present invention where the finite image is "invisible"; Figure 2 is a side view of Figure 1; Figure 3 is a view of the document shown in Figure 1 at a predetermined angle reflecting the "visible" finite image, - Figure 4 is a side view of Figure 3; Figure 5 is a side sectional view of Figure 1 along line 5-5; Figure 6 is a side sectional view of Figure 3 along line 6-6; Figure 7 is an enlarged perspective view of a fragment of Figure 5 along line 7-7; and Figure 8 is an enlarged sectional view of Figure 7 along line 8-8. Classification of the diagram of Figure 5; Solid line = line ds printed color and step; and dotted lines = line of printed COI L and step with registration in an enhanced line. Detailed Description of Preferred Modalities and Intent In this specification, you use the words "print rt and" print "to refer to the creation of an original security document resistant to counterfeiting 10 despite the techniques used and the words" copy " and "reproduction" to refer to making reproductions of an original either through a copier or through the reproduction technology (scanner). In the present invention, the security document 10 has two essential elements as shown in Figure 7. The two essential elements are somewhat of printed lines 12 of color and a step and a few lines of enhanced highlighting 14 with registration on a part of the printed lines 12 to form a finite image 16. The term "document" was used here to refer to any type of material that has been printed where someone or a society requires material that contains safety sieves resistant to fake, t-ales as it is packed, tickets for events or the paper of security already described. The term "Finite Image" is used here to show the signs on an original document that at a distance is invisible at first sight, when it is seen'1' is a perpendicular angle to the surface: from document 10 as shown in Figures i and 2 and is easily seen when document 10 is viewed (4) at angles not perpendicular to the plane of the document as shown in Figures 3 and 4, the term "Enhanced Mines" "14 as used in this invention / n: refers to the current lines printed ds odor, but to the marked lines that are in the substrate of the document 10. formed in the design of a line when the highlight is made The term "line is)" was used in this specification to refer to any type of line, such as continuous, - circles, - straight, wavy, broken and dotted. According to one embodiment of our invention, as shown in Figure 5, we have provided an original document 10, Document 10 has a support having a side comprising a printed surface.On the printed surface, the locum ntc 10 has a both 12 color lines and one step. both of the lines 12 are superimposed and with registration on the highlighted lines 14 to form the finite image 16. The finite image 16 is the word figures 1 and 3 although no graphic letter, word or symbol will indicate to the recipient whether the document 1 '! it is an authentic original document. The finite image 16 is valid only when the highlighted lines 14 are with register in the portion of both the lines 12 that form the finite image 16. The lines 12 can have a width como as shown in Figure 8) between .0005 and in CT. or? üiti ... .015 inches, but preferably they are of uniform width between .0015 and cm. or me .008 inches The amount of spacing or line spacing (P) of lines 12 may be between 50 and 200 lines per inch, and the spacing between the lines of the line 12 is almost equal. lines per inch and an ideal pass is from 90 to almost 133 lines per inch.When seen at first glance, both lines 12 will appear to present a continuous pattern.The only requirement for the step space (P) is that when the original document 10 is viewed (1) perpendicularly, the finite image 16 is "invisible" and when the document 10 is copied, the finite image 16 is "invisible" at all angles. In -this embodiment of the invention as shown in Figure 7, the finite image is formed when a portion of both lines 12 is recorded in the raised lines 14. How etching was used in this embodiment of the present invention , causes the embossment of the substrate of the security document 10 to be compressed to form embossed lines 14 on the portion of the printed line both 12, to fall into the shadows of the relief as shown in Figure 8. Emboss 14 may fall sn &1 reverse side of the original document as a means of alternative verification of the originality of a document 10. These alternative means of verification are not always desired, since the highlighting on the reverse side of document 10 may be suppressed by the placement of a plate on the back of document 10 when document 10 is enhanced. As shown in Figure 8, the engraving 14 has a width that varies between (l) the width of the printed line 12 to about 20% more than the width () of the printed line 12. Preferably, the etching base should have a width equal to the width of the part of line 12 that is being enhanced. In addition, the depth (D) of the enhancement 14 is equal to or greater than the width (W) in the part of the printed line 12 that has been enhanced. In this case, when the present invention is viewed from a non-perpendicular angle, a negative white image of the finite image appears and the highlighted lines are hidden. refers to the color of the paper of the document 10. The negative "white" image 24 of the finite angled image 12 of the present invention is illustrated in Figure 6. The printed lines both 12 can be drawn by hand, by computer, film or typographic clichés and in particular offset printing, all known to those who know the subject, or as it is also o? noo "i" 5. / es is to create it is passed to an electronic program or disc (diskette) to transfer the images directly to the plate or print it using the pregrismador disk in any laser printer or other device of conventional quality.Although it is not necessary- without embarking, the pantographs or designs can be printed inverted out of the normal pattern by plo axis / ti cloud pattern previously identified For o?Having optimum security, the invention can also be used in conjunction with other methods, such as, using a visible image as already described to produce a moiré diagram, for example in Patents 5, 18.7 * 57 and 5,193,853, the latter revealed that the lines can be at a desired step deliberately selected so that they go into detail of the identification (scanner) in the known copying machines and video options. After the security document 10 has some printed lines 12, the security document is placed on a conventional enhancement machine where the portion of the lines 12 to be enhanced and registered with the highlighted lines are equalized. with < ,a plate. The document 10 is enhanced with a conventional machine for enhancement by known methods such as clichés, commonly used in enhancement printing. In an alternative mode of this process, the same printing machine can print and enhance simultaneously. In a third alternative mode of this process, the enhancement occurs first and the impression is applied to the document later. Although our invention is described in reference to specific preferred embodiments. it is clear that variations or use of another type of material can be made without departing from the spirit of the invention as claimed.
