  • Publication number: 20090136866
    Abstract: Methods of making a stenciled screen for use in screen printing an image onto a substrate are generally disclosed. The method involves removing a portion of a transfer coating from a transfer sheet via heat transfer with a printable sheet defining a printable surface. The portion of the transfer coating removed from the transfer sheet corresponds to areas where an ink is present on the printable surface of the printable sheet. The transfer coating can then be transferred to a screen to form a stenciled screen having closed mesh areas corresponding to where the transfer coating is present. The stenciled screen can then be used to screen print an image onto any of a variety of fibrous substrates.

  • Publication number: 20090110850
    Abstract: Methods and products for forming a coated image on a substrate are generally disclosed. The methods can include forming an image on a printable surface of a transfer coating layer of a printable transfer sheet. In a separate step, the negative mirror image of that same image is printed with toners on a toner printable sheet. After registering the sheets together, a portion of the transfer coating layer of the printable transfer sheet is transferred to the toner printable sheet, such that the portion of the transfer coating layer transferred to the toner printable sheet corresponds to the imaged areas on the toner printable sheet. However, the image formed on the printable surface of the transfer coating layer and the underlying transfer coating substantially remain on the printable transfer sheet. Thereafter, the image and the transfer coating layer remaining on the printable transfer sheet are transferred to a substrate.

  • Publication number: 20090111039
    Abstract: Methods of making fibrous webs having a visible transparency variation image and products constructed from such methods are generally disclosed. The variation in transparency creates a transparency variation image in the fibrous substrate in the form of a false watermark and/or a false shadow mark. In the method disclosed, a transfer sheet having a transfer coating is utilized. A portion of the transfer coating is removed from the transfer sheet by heat transfer with a printable sheet having a toner image applied thereon. The transfer coating of the transfer sheet includes a powdered thermoplastic polymer and a film-forming binder. The film-forming binder can have a melting point that is less than that of the powdered thermoplastic polymer. In the final step of the method, the remaining transfer coating is transferred to a fibrous substrate to form the transparency variation image in the fibrous substrate.

  • Publication number: 20090061351
    Abstract: In one embodiment, a method of applying an image to a substrate includes the steps of: imaging a printable surface with an image to form an imaged surface having a printed area and a non-printed area; positioning a masking sheet comprising an outer masking layer adjacent the imaged surface such that the outer masking layer is in contact with the imaged surface; transferring a corresponding portion of the outer masking layer to the printed area of the imaged surface, leaving a negative image mask on the masking sheet; transferring the negative image mask to a transfer layer of a heat transfer paper to form a heat transfer paper having a masked portion corresponding to the negative image mask and an unmasked portion; and transferring the unmasked portion corresponding to the printed area to a substrate. Other methods of making and using negative image masks are also disclosed.

  • Patent number: 7364636
    Abstract: The present invention was directed to a unique heat transfer material for use in transferring an image-bearing coating onto a substrate, such as an article of clothing. The heat transfer material of the present invention may be used in cold peel transfer processes, resulting in an image-bearing coating having superior washability, compared to conventional image-bearing coatings. Additionally, the materials may be used on dark colored fabrics without graying of the opaque background or dulling of colored images typically associated with printing on darker fabrics. The heat transfer material of the present invention produces superior results due to the addition of crosslinking agents to the coatings.

  • Patent number: 7361247
    Abstract: A heat transfer material kit is disclosed that includes a first heat transfer material that includes a printable, peelable transfer film, and a second, different heat transfer material that includes an overlay transfer film. A method of using the kit is disclosed that includes the steps of a) imaging the printable, peelable transfer film of the first heat transfer material, b) separating the imaged printable, peelable transfer film from the first heat transfer material, c) positioning the second heat transfer material and the imaged printable, peelable transfer film adjacent a substrate, and d) transferring the imaged printable, peelable transfer film and the overlay transfer film to the substrate. Alternate methods of using the kit are also disclosed. Images transferred using the overlay transfer film provide good image appearance and durability.

  • Patent number: 7238410
    Abstract: The present invention is directed to a unique heat transfer material for use in transferring a discontinuous coating onto a substrate, such as an article of clothing. The heat transfer material of the present invention may be used cold peel transfer processes, resulting in an image-bearing coating having superior crack resistance, washability, and breathability compared to conventional image-bearing coatings. Additionally, the materials may be used on dark colored fabrics without washed-out appearance typically associated with printing on darker fabrics. The heat transfer material of the present invention produces superior results due to the use of discontinuous coatings.

  • Patent number: 6916751
    Abstract: The present invention is directed to a heat transfer material containing a first (interior) meltable layer, a second (surface) meltable layer, and a release coating layer separating the first and second meltable layers. During a transfer process, the first (interior) meltable layer, release coating layer, and second (surface) meltable layer penetrate into the yarn interstices, or other undulations, of a given substrate to be coated. Only the second (surface) meltable layer transfers to the substrate, resulting in a thinner transfer coating compared to conventional coatings. The present invention is also directed to a method of making a printable heat transfer material and a method of forming an image-bearing coating on a surface of a substrate using the printable heat transfer material in a hot or cold peelable transfer process.
