Patent number: 6974609Abstract: Image transfer media and methods of transferring images are provided. The image transfer media comprise a sheet having a nonporous micro-embossed surface topography comprising cavities on one major surface of the sheet and an ink release coating on the embossed surface, wherein said major surface has a surface energy of about 43 dyne/centimeter or less. A method of transferring an image to a substrate comprises the steps of (a) printing a selected image onto an imaging surface of an image transfer medium of the invention; (b) contacting the imaged micro-embossed surface with the substrate using pressure; and (c) removing the micro-embossed surface of the image transfer medium from the substrate.Type: GrantFiled: February 19, 2003Date of Patent: December 13, 2005Inventors: Lori P. Engle, Omar Farooq, Paul D. Graham, Jonathan P. Kitchin, Lisa M. Miller, David W. Tweeten

Patent number: 6913722Abstract: A receptor medium with a sheet having an optically transmissive microembossed imaging surface as one major surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, and combinations thereof. The microembossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium and also Moire' effects but also provides sufficient optical transmissivity to be useful as overhead transparency media, backlit signage, and the like. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained without creation of the Moire' effects. Methods of making and using the inkjet receptor medium are also disclosed.Type: GrantFiled: December 23, 2002Date of Patent: July 5, 2005Assignee: 3M Innovative Properties CompanyInventors: Lori P. Engle, Robert T. Fehr, Patrick R. Fleming, Alan G. Miller, Todd R. Williams, Caroline M. Ylitalo

Patent number: 6649249Abstract: A receptor medium with a sheet having a random microembossed imaging surface as one major surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, electrically, thermally, or magnetically modifiable materials, and combinations thereof. The random microembossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium and also Moire' effects. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained without creation of the Moire' effects. Methods of making and using the inkjet receptor medium are also disclosed.Type: GrantFiled: May 31, 2000Date of Patent: November 18, 2003Assignee: 3M Innovative Properties CompanyInventors: Lori P.
