Obscuring residual images on print ribbons
Techniques are described for obscuring residual images on print ribbons that have been used to print on plastic cards in order to prevent access to sensitive or personalized data appearing in the residual images. An image is printed on a retransfer film using the print ribbon, thereby creating a residual image of the printed image on the print ribbon. The retransfer film is then used to obscure some or all of the residual image on the print ribbon by transferring ink from the section of the print ribbon containing the residual image onto the retransfer film. In some embodiments, obscuring the residual image on the print ribbon occurs before the printed image on the retransfer film is transferred to the plastic card.
Method and apparatus of decorating a metallic container by digital printing to a transfer blanket
An apparatus and methods of decorating a metallic container are provided. More specifically, the present invention relates to apparatus and methods used to provide a decoration or indicia on a predetermined portion of an outer surface of a metallic container body. The decorator includes at least one digital print unit, a transfer blanket, and a support element. The digital print unit transfers a decorating material to the transfer blanket to form a decoration on the transfer blanket. The support element then moves a metallic container into contact with the transfer blanket. In this manner, the decorating material is transferred to an exterior surface portion of the metallic container to decorate the metallic container. In one embodiment, the digital print unit is an electrophotographic system which transfers a toner material to the transfer blanket. In another embodiment, the digital print unit includes an inkjet print head which transfers an ink to the transfer blanket. Optionally, the decorator may include two or more support elements.
IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD
An image forming apparatus includes: a first image forming unit that forms a clear toner image with a clear toner; a second image forming unit that forms a color toner image with a color toner; a transfer unit that transfers at least one of the clear toner image and the color toner image onto a medium; and a controller that controls formation of the clear toner image and the color toner image. When the medium is a heat transfer medium and the color toner image is formed on the heat transfer medium, the controller performs control so that the clear toner image is formed on a region where the color toner image is formed and a weight per unit area of the color toner is less than 0.29 mg/cm.sup.2, and a weight per unit area of the clear toner image is 0.15 to 0.55 mg/cm.sup.2.
Heat transfer films for the dry coating of surfaces
A heat transfer film having a) a carrier film, b) at least one coating layer arranged directly on the carrier film, and c) at least one hot-sealable polymer adhesive layer is disclosed. The coating layer is based on a non-aqueous, radiation-curable, liquid composition which contains at least 60 wt %, based on the total weight of the composition, of curable constituents selected from organic oligomers which have ethylenically unsaturated double bonds. Use of the heat transfer films for the dry coating of surfaces, production of such heat transfer films, and methods for coating or lacquering surfaces of objects using the heat transfer films are also disclosed.
TRANSFER MEMBER FOR PRINTING SYSTEMS
There is disclosed a layered article that can be used in indirect printing, in analog or digital processes. The layered article, when configured as a transfer member, may serve to receive an ink in any form, allow the ink to be treated so as to form an ink image, and permit the application of the ink image on a substrate. The transfer member comprises a support layer and an imaging layer, which may be formed of a silicon matrix including dispersed carbon black particles. Methods for preparing the same are also disclosed.
Variable tension and/or transport speed retransfer printing process
Retransfer printing methods and systems are described where a variable stripping process is utilized while stripping all or a portion of the retransfer film (also known as intermediate transfer media) from the surface of a substrate. The variable stripping process includes stripping the retransfer film from different sections of the substrate surface while applying different tensions to the retransfer film and/or at different transport speeds of the retransfer film and the substrate.
Transfer printing
Examples described herein include printing systems that include a transfer medium, a binder material applicator to apply a layer of binder material to a surface of the transfer medium, and a print engine to apply printing material to the layer of binder material. The system can also include a roller to press the transfer medium against a print medium to transfer the binder material and the printing material to the print medium.
THERMAL TRANSFER RIBBON ASSEMBLY COMPRISING A METAL LAYER AND A PROTECTIVE COATING LAYER
A method for introducing a reflective and/or diffractive metallic variable and/or non-variable image to a substrate by use of thermal transfer printing includes simultaneously transferring a defined portion of each of a protective coating layer, a metal layer, and an adhesive layer from a carrier film of a transfer ribbon to the substrate by applying heat to the transfer ribbon. The defined portions of the metal layer and the protective coating layer are adhered to the substrate using the adhesive layer. Subsequent to transferring the protective coating layer, the metal layer, and the adhesive layer, durability is provided to the metal layer by cross-linking the protective coating layer that is over the metal layer by exposing the protective coating layer to a radiation source after the defined portions of the protective coating layer, the metal layer, and the adhesive layer are transferred from the carrier film.
Perimetric decoration by sublimation
A sublimation transfer sheet including a backing layer positionable between overlapping end portions of the sublimation transfer sheet, method of using the same, and object decorated with method of using the same. Preferably, the backing layer is an absorbent layer. Also preferably, the backing layer is secured to a side of a release layer facing away from a side of the release layer having dyes or inks thereon.
Digital printing process
An aqueous treatment composition for ITM (Intermediate transfer member) of a printing system and a method of printing comprising the step of applying said treatment composition to the surface of an ITM, wherein said treatment composition comprising: at least 3% wt quaternary ammonium salt, at least 1% wt water soluble polymer, and at least 65% wt water. Also disclosed, a printing system comprising a an ITM and treatment station for forming a thin layer of liquid treatment formulation on the ITM surface.
