Abstract:
A printer for digital printing in which ink is deposited in metered amounts on a substrate. The printer includes a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and a segment of wire disposed around the wheel and the idler. A computer controls movement of the wire by controlling the rotation of the wheel. As the motor rotates the wheel, ink contained within the paint reservoir coats the wire and is drawn by the wire in front of an air stream, which pulls the ink from the wire and carries it toward the substrate. The wire has alternatively hydrophilic and hydrophobic areas, causing the ink to form droplets on the wire for printing them as discrete pixels onto the substrate.
Abstract:
An improved adhesive applicator or fluid delivery system (1) immerses a wire in a reservoir of adhesive for a period of time sufficient to allow the wire to be coated with the adhesive, (2) places the coated wire in close proximity to a designated medium onto which the adhesive will be applied, and (3) directs a stream of gas to contact the coated wire and to thereby cause at least some of the adhesive on the wire to be deposited onto the designated medium. The speed of the wire and the force of the air stream may be digitally controlled by a processor, controller, microprocessor, or other computing device to ensure that a desired image resolution is achieved. Because the fluid delivery system is free of most of the mechanical limitations of traditional ink jet print heads, the system is compatible with adhesive application. When compared to the traditional coating operations for adhesives, the fluid delivery system allows controlled delivery, both in terms of location on the print medium and drop size (and thus coat weight). The system thus allows for greater positional and coat weight control of adhesives on the print medium or substrate, which is especially useful where precise control is desired.
Abstract:
Retroreflective sheeting articles comprising a colorless thermal mass transferred image, methods of thermal mass transfer printing substrate such as polymeric films with a colorless thermal mass transferable composition, and thermal mass transfer ribbon articles comprising a colorless thermal mass transferable composition are described. The thermal mass transfer composition comprises a homogeneous unreactive thermoplastic composition comprising at least one acrylic resin and less than 3 wt-% of components that are opaque at ambient temperature.
