Patent number: 5601887Abstract: Cards and methods of securing hidden symbols on cards are disclosed. The cards, such as instant-win lottery tickets, utilize continuous overprint inks that mask the boundaries between their "secure" and "unsecure" portions to inhibit unscrupulous players from successfully tampering with them. By reformulating the overprint inks to permit a single set to be applied to both portions of a card, more vibrant and aesthetically-pleasing graphics may be displayed as well while utilizing fewer printing stations during the printing process.Alternatively or additionally, the cards may be embossed for added security. Raising portions of the secure area of a card above the remainder of its surface produces irregular features, thereby inhibiting both improper removal of the upper latex or other coating and photo reproduction of the card. The varying card height caused by embossing further inhibits heat-based tampering, as heat transfer to the irregular surface is no longer uniform.Type: GrantFiled: May 30, 1995Date of Patent: February 11, 1997Assignee: Dittler Brothers IncorporatedInventors: Benny R. Rich, James J. Carides, Jon M. Brawner

In this arrangement, any removal of the film does not affect the visible indicia, but the region in the vicinity of the visible indicia is destroyed. The non-adherent visible indicia may take the form of any predetermined pattern such as the term void to indicate to a viewer that the overlying protective film has been removed.Type: GrantFiled: June 7, 1995Date of Patent: December 31, 1996Assignee: FLEXcon Company, Inc.Inventors: Richard T.

Badge is issued, the inked substrate is attached to the base substrate, the inked substrate covering the void indicia area. The overlay substrate is then placed over and attached to the inked substrate, the ink dissolver in contact with the soluble ink of the ink substrate. The ink dissolver of the overlay substrate contacts and coacts with the soluble ink of the inked substrate to dissolve the ink and allow the ink to migrate through to the overlay substrate to the display surface, where it can be visually perceived, in a preselected time interval.Type: GrantFiled: April 9, 1993Date of Patent: November 15, 1994Assignee: S.J.A.

Patent number: 5364735Abstract: An optical recording medium in which a recording layer (4) on which optically readable data are recorded is formed on a rectangular base material (1), a protective layer (5) is formed by roll coating on the recording layer (4) and wherein the base material (1) on which the recording layer (4) and the protective layer (5) have been formed is cut into a predetermined shape. The protective layer (5) provided on the recording layer (4) is formed of a material having a low Young modulus and a lower thermal conductivity as compared with the base material.Type: GrantFiled: August 27, 1992Date of Patent: November 15, 1994Assignee: Sony CorporationInventors: Junichi Akamatsu, Masato Yamamura

Patent number: 5358281Abstract: A security label is constructed from label stock having top and bottom faces. A release coat is provided on the label stock bottom face, a non-opaque tie coat provided on the release coat, and an opaque coat of permanent pressure sensitive adhesive provided on the tie coat. The tie coat has a significantly greater affinity for the adhesive than for the release coat. Indicia, such as reverse printed alphanumeric characters, is provided on the tie coat substantially between the adhesive and the tie coat so that "void", or a similar security designation, is indicated if the label stock is removed. A release liner may cover the permanent pressure sensitive adhesive, or paper stock having a second tie coat with repositional adhesive over the tie coat may be provided engaging the permanent pressure sensitive adhesive.Type: GrantFiled: February 10, 1993Date of Patent: October 25, 1994Assignee: Moore Business Forms, Inc.Inventor: Walter G. Greig

Patent number: 5350199Abstract: A printing medium (10) receives and displays images produced by a thermal printer of a standard facsimile machine. The printing medium (10) comprises plain-surfaced printing paper (12) and a cover medium (14) disposed over the printing paper so as to pass through the facsimile machine in combination with the printing paper. The cover medium (14) includes a bottom surface facing toward the printing paper (12) and a top surface facing away from the printing paper. A coating of heat-transferable ink (16) is disposed on the bottom surface, the ink being transferred from the cover medium (14) to predetermined locations on the printing paper (12) as the printing medium passes through the facsimile machine.Type: GrantFiled: September 17, 1993Date of Patent: September 27, 1994Inventors: Aurelia G. Young, Peter A. Hochstein

Patent number: 5346259Abstract: The present invention is a tamper proof label comprised of a thicker support portion and a thinner fragile portion. The label is formed of a plurality of layers of varnish, adhesive, plastic, and ink. The label incorporates an authentication region in which the text can be readily deciphered only with a special viewer. The top surface of the label can be written on with ink and is difficult to erase without destroying the fragile portion of the label. The label is adhered to a product by an adhesive which becomes aggressively bonded to the product over a relatively short period of time. In addition, the adhesive leaves a residue which is visible when illuminated with ultraviolet light.Type: GrantFiled: July 16, 1992Date of Patent: September 13, 1994Assignee: Avery Dennison CorporationInventors: Anton Mocilnikar, Charles K.

Patent number: 5344191Abstract: A hidden entry system comprises a document having a localized coating of a non-pressure sensitive heat activated autogenous chromogenic composition to provide a latent image which reveals hidden indicia when heated at moderate temperatures. The hidden entry system is especially useful for contests and promotional forms. Quickly striking the chromogenic composition with a fingernail or blunt object converts the latent image to a visible colored image by frictional heat. The chromogenic composition contains a chromogenic compound and a color developer which are non-pressure sensitive and non-reactive at room temperature. The latent image can be provided by an intimate mixture of the chromogenic compound and the developer or alternatively, one component can be printed on a separate layer or coating of the other component.Type: GrantFiled: December 9, 1992Date of Patent: September 6, 1994Assignee: Wallace Computer Services, Inc.Inventors: John C. H. Chang, Peter A. Walter

Patent number: 5340159Abstract: An improved security document according to the present invention includes a substrate having a surface for carrying indicia. The document has background printed matter, consisting of a pattern of elements of a first size and frequency, printed at a first density on the surface. The document further has a cancellation term, consisting of a pattern of elements of a second size and frequency, printed at a second density on the surface. Elements of one of the first size or the second size are sufficiently small such that they are not reproduced by a color copier at a particular copier setting, and elements of the other of the first size or the second size are sufficiently large such that they are reproduced by the color copier at the particular copier setting. As a result, a copy of the security document made on a color copier displays the cancellation term. At least a portion of the security document surface is divisible into a plurality of bands extending across the surface.Type: GrantFiled: March 1, 1993Date of Patent: August 23, 1994Assignee: The Standard Register CompanyInventor: William H. Mowry, Jr.

Patent number: 5340158Abstract: A shipping label that also functions as a packing list comprises a packet having a self-adhesive feature for attaching it to a shipping package with the same security of nonremovability as a standard shipping label. The packing list forms which are under the covering layer of the packet are multilayer composites that stick to the carton when applied but leave the sticky layer when pulled away. The packing list form has a place for the shipping address. The covering layer for the packet is opaque with a clear window overlaying the shipping address area. A packet may contain a plurality of packing list forms stuck one on top of the other. When each packing list form is pulled up it leaves a nonstick film on the one below it.Type: GrantFiled: October 12, 1993Date of Patent: August 23, 1994Assignee: Best Label Co., Inc.Inventor: James C.
