Patent number: 6902641Abstract: A method of labelling an article is carried out by providing a heat-transfer label that includes a support portion and a transfer portion over the support portion for transfer of the transfer portion from the support portion to the article upon application of heat to the support portion while the transfer portion is placed in contact with the article. The transfer portion comprises a single or multiple color design. The transfer portion then is transferred from the support portion to the article. The method is particularly well-suited with silane-treated glass containers of the type that are subjected to pasteurization conditions, regardless of whether the glass containers have been pre-treated previously with polyethylene, oleic acid, stearate or the like.Type: GrantFiled: January 28, 2003Date of Patent: June 7, 2005Assignee: Gotham Ink CorporationInventors: Mukund R. Patel, Robert E. Lafler

Patent number: 6797747Abstract: A heat-transfer label is particularly well-suited for use on silane-treated glass containers of the type that are subjected to pasteurization conditions, regardless of whether the glass containers have been pre-treated previously with polyethylene, oleic acid, stearate or the like. The heat transfer label comprises (a) a support portion consisting of a sheet of paper or film overcoated with a layer of releasable material such as polyethylene and (b) a transfer portion over said support portion for transfer of the transfer portion from the support portion to an article, upon application of heat to the support portion, and placing the transfer portion in contact with the article.Type: GrantFiled: January 3, 2002Date of Patent: September 28, 2004Assignee: Gotham Ink CorporationInventors: Mukund R. Patel, Robert E. Lafler

Patent number: 6610397Abstract: A heat-activatable, alkali-removable labelling system comprises a support portion and a transfer portion over said support portion for transfer of the transfer portion from the support portion to an article upon application of heat to the support portion while the transfer portion is placed in contact with the article. The transfer portion comprises an optional, optionally alkali-removable, organic solvent soluble acrylic protective layer; an optionally alkali-removable, organic solvent soluble ink layer over said protective layer; and an alkali-removable, heat-activatable, organic solvent soluble acrylic adhesive layer over said ink layer.Type: GrantFiled: March 20, 2001Date of Patent: August 26, 2003Inventors: Mukund R. Patel, Robert E. Lafler

Patent number: 4919044Abstract: A wet laid watermark of uncoated paper is simulated by the use of a resin or resin-plasticizer mixture dissolved in a slow evaporating, high boiling solvent. A sufficient quantity of the low viscosity solution is printed onto an uncoated paper sheet of stationery grade by a standard flexographic press to penetrate the paper fiber and deposit a non-tacky solid having a refractive index which closely approximates that of cellulose. The resulting image of the print is visible to both faces of the paper sheet.Type: GrantFiled: December 5, 1988Date of Patent: April 24, 1990Assignee: Westvaco CorporationInventor: Robert E. Lafler

Patent number: 4786532Abstract: This process is directed to the coloration of envelope and stationery grades of white paper stocks with a water based ink coating. Characteristics of the flexographic process include both press and ink specifications. Critical mechanical or material characteristics are associated with each of the fountain roll, the anilox roll, the plate roll and the impression roll of a flexographic printing system. Used in conjunction with the critical combination of press characteristics is a unique, water-based ink formulation for rapidly coloring an entire web side with a colored ink to simulate the appearance of a colored paper stock.Type: GrantFiled: May 11, 1987Date of Patent: November 22, 1988Assignee: Westvaco CorporationInventors: Richard C. Brown, Robert E. Lafler, Joseph M. Murphy

Patent number: 4600629Abstract: The present printing process provides a unique color tone print of muted contrast in two, sequentially operated, flexographic print stations. A suitable paper substrate base for the process is uncoated white paper of stationery or envelope grade. As the paper supply web is drawn through the first print station, the desired image or design is printed on the paper with a colorless solution of a polyol, such as glycerine, in a glycol ether solvent. The second print station simply lays a uniform color coating of compatible pigment or solvent dye based ink over the entire web surface. Shade or tone differences resulting from differences in ink absorption with respect to the glycerine solution image areas provide a distinctive printed product.Type: GrantFiled: September 16, 1985Date of Patent: July 15, 1986Assignee: Westvaco CorporationInventors: David H. Knapp, Robert E. Lafler

Patent number: 3933094Abstract: In a method for making a business reply envelope having binary bar code indicia imprinted thereon for identification or read-out by infrared scanning apparatus, the steps of providing a plurality of printing inks, each of said inks being of a color which in combination with the envelope substrate yields a Print Contrast Signal substantially less than 50 percent when measured in the wavelength range of 800 to 900 nanometers as determined by the equation Print Contrast Signal = Rw-Rb/Rw .times. 100 wherein Rw is the percentage reflectance of the unprinted substrate of the envelope and Rb is the percentage reflectance of the printed area of the envelope, adding a material comprising a metallic compound to only one of said inks in quantity sufficient to increase the Print Contrast Signal of said one ink color and said substrate to at least 50 percent, imprinting at least said indicia on said substrate with said one ink, and imprinting further material on said substrate with the other of said inks.Type: GrantFiled: November 19, 1973Date of Patent: January 20, 1976Assignee: United States Envelope CompanyInventors: Joseph M.
