Decal print process
Backing material is passed by a first heater to pre-heat the backing material. The backing material is then passed by a printing engine to print marking material on the backing material, and passed by a first light source to apply ultra-violet (UV) light to the marking material printed on the backing material, to partially cure the marking material. Further, the backing material is passed by a container to expose the partially cured marking material to adhesive particles to cause the adhesive particles to adhere only to the marking material. The backing material is passed by a second light source to apply additional UV light to the marking material partially cured on the backing material to fully cure the marking material. Finally, the backing material is passed by a second heater to melt the adhesive particles that are adhered to the marking material on the backing material.
1. An apparatus comprising:
a first heater positioned to pre-heat backing material;
a printing engine positioned to receive said backing material from said first heater and print marking material on said backing material after said backing material has been pre-heated by said first heater, during said printing, said backing material lacks an adhesive background;
a first light source positioned to receive said backing material from said printing engine and apply ultra-violet (UV) light to said marking material printed on said backing material to partially cure said marking material;
a container positioned to receive said backing material from said first light source and expose said marking material partially cured on said backing material to airborne adhesive particles to cause said adhesive particles to adhere to said marking material partially cured on said backing material;
a second light source positioned to receive said backing material from said container and apply additional UV light to said marking material partially cured on said backing material to fully cure said marking material; and
a second heater positioned to receive said backing material from said second light source and melt said adhesive particles that are adhered to said marking material on said backing material.
2. The apparatus according to claim 1 , movement of said backing material through said container forms a mono-layer of said adhesive particles on said marking material.
3. The apparatus according to claim 1 , said container comprises a removal structure positioned to remove excessive adhesive particles from said marking material partially cured on said backing material as said backing material exits said container.
4. The apparatus according to claim 1 , said container comprises an enclosed interior having openings positioned to allow said marking material to enter and exit said enclosed interior.
5. The apparatus according to claim 1 , said container comprises a removal structure positioned to remove excessive adhesive particles to leave said adhesive particles only on said marking material.
6. The apparatus according to claim 1 , wherein total energy and power values of said first light source are set to form only interior bonds of said marking material and prevent said marking material from running, while keeping an outer surface of said marking material tacky.
7. The apparatus according to claim 1 , said first light source is positioned to receive said backing material from said printing engine within a time limit after said printing engine has printed said marking material on said backing material that is less than an amount of time in which said marking material seeps into said backing material.
8. An apparatus comprising:
a printing engine positioned to print marking material in a pattern on backing material while said backing material lacks adhesive;
a first light source positioned to receive said backing material from said printing engine and apply light to said marking material printed on said backing material to partially cure said marking material;
a container positioned to receive said backing material from said first light source and expose said marking material partially cured on said backing material to adhesive particles to cause said adhesive particles to adhere to said marking material partially cured on said backing material;
a second light source positioned to receive said backing material from said container and apply additional light to said marking material partially cured on said backing material to fully cure said marking material; and
a heater positioned to receive said backing material from said second light source and melt said adhesive particles that are adhered to said marking material.
9. The apparatus according to claim 8 , movement of said backing material through said container forms a mono-layer of said adhesive particles on said marking material.
10. The apparatus according to claim 8 , said container comprises a removal structure positioned to remove excessive adhesive particles from said marking material partially cured on said backing material as said backing material exits said container.
11. The apparatus according to claim 8 , said container comprises a removal structure positioned to remove excessive adhesive particles to leave said adhesive particles only on said marking material.
12. The apparatus according to claim 8 , said container comprises an enclosed interior having openings positioned to allow said marking material to enter and exit said enclosed interior.
13. The apparatus according to claim 8 , wherein total energy and power values of said first light source are set to form only interior bonds of said marking material and prevent said marking material from running, while keeping an outer surface of said marking material tacky.
14. The apparatus according to claim 8 , said first light source is positioned to receive said backing material from said printing engine within a time limit after said printing engine has printed said marking material on said backing material that is less than an amount of time in which said marking material seeps into said backing material.
15. An apparatus comprising:
a printing engine positioned to print marking material in a pattern on backing material while said backing material lacks adhesive;
a first light source positioned to receive said backing material from said printing engine and apply light to said marking material printed on said backing material to cure less than all bonds of said marking material;
a container positioned to receive said backing material from said first light source and expose said marking material on said backing material to adhesive particles to cause said adhesive particles to adhere to said marking material; and
a second light source positioned to receive said backing material from said container and apply additional light to said marking material to fully cure all remaining bonds of said marking material.
16. The apparatus according to claim 15 , movement of said backing material through said container forms a mono-layer of said adhesive particles on said marking material.
17. The apparatus according to claim 15 , said container comprises a removal structure positioned to remove excessive adhesive particles from said marking material partially cured on said backing material as said backing material exits said container.
