Marking material for laser glossing systems and methods
View Patent ↗A system for generating a differential gloss image includes a marking material having absorbing elements useful for absorbing electromagnetic radiation emitted by a laser glossing imager, and accommodating heating and resultant melting of the marking material for altering a surface of the marking material image. The absorbing element is a pigment or dye. The absorbing element is carbon black, or a pigment capable of absorbing IR light, while being transparent to visible light.
1. A marking material system for generating a differential gloss image using a laser glossing imager configured to expose a portion of a printed image to electromagnetic radiation, comprising:
a marking material for forming the printed image; and
an absorbing element configured to absorb the electromagnetic radiation, the absorbing element being a component of the marking material,
wherein the absorbing element being disposed in the marking material in a concentration sufficient to impart an attenuation length of 0.5 to 10 micrometers in the marking material.
2. The system of claim 1 , the marking material further comprising:
a resin or binder, the resin or binder being a resin or binder that melts at a temperature of less than 250 degrees Celsius.
3. The system of claim 1 , the marking material further comprising:
a resin or binder, the resin or binder being a resin or binder that melts at a temperature of less than 150 degrees Celsius.
4. The system of claim 1 , the marking material further comprising a thermal plastic or wax the thermal plastic or wax being a thermal plastic or wax that melts at a temperature of less than 250 degrees Celsius.
5. The system of claim 1 , the marking material comprising at least one colorant component, the absorbing element comprising at least one of the at least one colorant component.
6. The system of claim 5 , the absorbing element further comprising:
a pigment.
7. The system of claim 5 , the absorbing element further comprising:
a dye.
8. The system of claim 5 , the absorbing element further comprising:
carbon black.
9. The system of claim 1 , the laser glossing imager comprising an IR laser, the absorbing element being IR light absorptive.
10. The system of claim 9 , the IR light absorptive absorbing element being transparent to visible light.
11. The system of claim 1 , the absorbing element having an un-even distribution in the marking material for enabling uneven heating of portions of the marking material when exposed to electromagnetic radiation from the laser glossing imager.
12. The system of claim 1 , the absorbing element being disposed in the marking material in a concentration of 0.1 to 5%.
13. A marking material system for generating a differential gloss image, comprising:
a marking material for forming the printed image, the marking material comprising an IR light absorptive absorbing element, the absorbing element being transparent to visible light; and
a laser glossing imager configured to expose a portion of the printed image to IR light for absorption by the absorbing element,
wherein the absorbing element being disposed in the marking material in a concentration sufficient to impart an attenuation length of 0.5 to 10 micrometers in the marking material.
14. The system of claim 13 , the absorbing element being a pigment.
15. The system of claim 13 , the absorbing element being a dye.
16. The system of claim 13 , comprising the absorbing element having a grainy distribution in the marking material.
