Method and apparatus for creating an image on an article, and article resulting therefrom
View Patent ↗A method of printing an image on an object includes the steps of: providing an object having an exterior surface having a planar portion and a channel recessed from the planar portion; applying a first ground coat on the exterior surface; drying the first ground coat; and spraying droplets of ink on the dried ground coat to form an image, wherein the droplets are sprayed from an ink jet printhead that is maintained at a constant distance from the plane of the planar portion of the object.
1. A molded object, comprising:
an exterior surface having a planar portion, a channel formed in said planar portion, and a prime coat;
a primary ground coat of pigment covering said exterior surface and the prime coat;
a photographic quality ink jet printed image overlaying and in surface-to-surface direct contact with said primary ground coat; and
a topcoat covering said ground coat and said image.
2. The molded object of claim 1 , wherein the primary ground coat further comprises a secondary coat of pigment covering said channel.
3. The molded object of claim 2 , wherein said secondary coat has a darker color than said primary coat.
4. The molded object of claim 1 , wherein said image has a dominant color and said primary ground coat has a color related to said dominant color.
5. The molded object of claim 1 , wherein said image covers at least a portion of said planar portion and a portion of said channel.
6. The molded object of claim 1 , wherein said image comprises a wood grain image.
7. The molded object of claim 1 , wherein the object is selected from the group consisting of a door skin, a door, a fixture, a fitting, a contoured building component, a furniture component, a window frame, a table, molded wall paneling, wainscot, and trim molding.
8. A method of forming an object comprising the step of:
providing a rectangular frame;
providing a molded object according to claim 1 , wherein the molded object is a first door skin;
providing a second door skin;
attaching the first and second door skins to the rectangular frame;
coating the first and second door skins with a sealant.
9. The method of claim 8 , wherein said step of applying droplets of ink onto the first door skin comprises the step of spraying droplets of ink having a diameter greater than about 20 pm against the first door skin.
10. The method of claim 8 , wherein said step of applying droplets of ink against the first door skin comprises the step of spraying droplets of ink having a diameter greater than about 30 pm against the first door skin.
11. The method of claim 9 , wherein said step of applying droplets of ink comprises the steps of providing an ink jet spray head for spraying droplets of ink and maintaining the ink jet spray head at a substantially constant distance from the planar portion of the door.
12. The method of claim 11 , wherein the substantially constant distance is less than about 15 mm from a bottom of the channel.
13. A molded object, comprising:
an exterior surface having a planar portion, a channel formed in said planar portion, and a prime coat;
a primary ground coat of pigment covering said exterior surface and the prime coat;
a photographic quality ink jet printed image overlaying and in surface-to-surface contact with said primary ground coat; and
a topcoat covering said ground coat and said image, wherein the molded object is a door skin.
14. The molded object of claim 13 , wherein the primary ground coat further comprises a secondary coat of pigment covering said channel.
15. The molded object of claim 14 , wherein said secondary coat has a darker color than said primary coat.
16. The molded object of claim 13 , wherein said image has a dominant color and said primary ground coat has a color related to said dominant color.
17. The molded object of claim 13 , wherein said image covers at least a portion of said planar portion and a portion of said channel.
18. The molded object of claim 13 , wherein said image comprises a wood grain image.
