Abstract
Hot foil printing apparatus (10) for printing letters, etc. on a surface of a plastics substrate in which the surface of the plastics substrate is presented to a heated die (16) and a printing tape (24) is compressed between the surface of the plastics substrate and the heated die to print the letters on the plastics substrate, and in which the surface of the plastics substrate is heated by heating apparatus (42) before it is presented to the heated die. Provides improved print quality and quicker throughput.
Claims11
A hot foil printing apparatus for printing letters or other devices on a surface of a plastics substrate, the hot foil printing apparatus comprising a workstation comprising a heated die having an outer surface with a print pattern thereon, a printing tape positioned adjacent the outer surface of the heated die and having a printing material thereon on the opposite side of the printing tape to the outer surface of the heated die, and holding means for securing the plastics substrate and for presenting the surface of the plastics substrate to the heated die such that the printing tape can be compressed between the surface of the plastics substrate and the outer surface of the heated die;
- and transfer means for moving the plastics substrate from a stored position to a second position in which the plastics substrate can be secured by the holding means;
- characterised in that the transfer means includes heating apparatus in close antecedent proximity to the heated die for heating the surface of the plastics substrate immediately prior to presentation to the heated die, such that the temperature of the surface of the plastics substrate is above room temperature when presented to the heated die.
A hot foil printing apparatus for printing letters or other devices on a surface of a plastics substrate, the hot foil printing apparatus comprising a workstation comprising a heated die having an outer surface with a print pattern thereon, a printing tape positioned adjacent the outer surface of the heated die and having a printing material thereon on the opposite side of the printing tape to the outer surface of the heated die, and holding means for securing the plastics substrate and for presenting the surface of the plastics substrate to the heated die such that the printing tape can be compressed between the surface of the plastics substrate and the outer surface of the heated die;
- and transfer means for moving the plastics substrate from a stored position to a second position in which the plastics substrate can be secured by the holding means;
- characterised in that the transfer means includes a bowl for storing the plastics substrate, a chute for moving the plastics substrate from the bowl, a rotatable transfer plate for moving the plastics substrate from the chute to the second position, and heating apparatus for heating the surface of the plastics substrate, such that the temperature of the surface of the plastics substrate is above room temperature when presented to the heated die, wherein the heating apparatus comprises a cartridge heater which is electrically powered and thermostatically controlled to operate at a substantially constant temperature.
