Decorating guitars
Apparatus and methods of decorating guitars and other stringed musical instruments are disclosed. In one aspect, an apparatus may include a carrier to hold a portion of a guitar, a surface to support the carrier, one or more ink-jet printheads to apply radiation-sensitive ink compositions on a surface of the portion of the guitar, when the portion of the guitar is held by the carrier, and when the carrier is supported by the surface, and a radiation source to supply radiation to the radiation-sensitive ink on the surface of the portion of the guitar. In another aspect, a method may include providing at least a portion of a guitar having a surface, and applying a decoration over the surface by spraying radiation-sensitive ink compositions over the surface with one or more ink-jet spray nozzles and exposing the radiation-sensitive ink compositions to radiation.
1. A method comprising:
providing a guitar part having a surface; and
applying a decoration that comprises a multi-colored rasterized representation of a digital image onto the surface of the guitar part with a guitar decorating apparatus by:
spraying light-activated inks onto the surface of the guitar part with ink-jet spray nozzles of the guitar decorating apparatus according to the multi-colored rasterized representation of the digital image; and
applying light to the light-activated inks, after the light-activated inks have been sprayed onto the surface of the guitar part, with a radiation source of the guitar decorating apparatus, to promote curing of the light-activated inks.
2. The method of claim 1 , further comprising positioning the guitar part in a cavity of a mold and placing the mold with the guitar part in the cavity on a print-bed prior to said applying the decoration.
3. The method of claim 1 , wherein the digital image comprises a multi-colored photograph.
4. The method of claim 1 , wherein said spraying comprises moving an ink-jet spray nozzle up and down based on a topography of the guitar part.
5. The method of claim 4 , further comprising measuring a distance to the surface of the guitar part, and wherein said moving the ink-jet spray nozzle up and down is based on the measured distance.
6. The method of claim 1 , wherein the representation of the digital image has photographic quality.
7. The method of claim 1 , wherein said applying the decoration comprises applying the decoration over substantially an entire top surface of the guitar part, and wherein the guitar part comprises a guitar body.
8. A method comprising:
providing at least a portion of a guitar having a surface; and
applying a decoration that comprises a multi-colored representation of a digital image over the surface of said at least the portion of the guitar with a guitar decorating apparatus by:
spraying a radiation-sensitive ink composition over the surface of said at least the portion of the guitar with one or more ink-jet printheads of the guitar decorating apparatus; and
exposing the radiation-sensitive ink composition to radiation from a radiation source of the guitar decorating apparatus after the radiation-sensitive ink composition has been sprayed over the surface of said at least the portion of the guitar.
9. The method of claim 8 , further comprising placing said at least the portion of the guitar in a carrier and placing the carrier having said at least the portion of the guitar on a movable bed prior to said applying the decoration.
10. The method of claim 9 , further comprising flipping the carrier having said at least the portion of the guitar over, placing the flipped over carrier having said at least the portion of the guitar on the movable bed, and printing on a surface on a back side of said at least the portion of the guitar in the flipped over carrier, wherein the back side of said at least the portion of the guitar is exposed when in the flipped over carrier.
11. The method of claim 8 , further comprising, prior to said applying the decoration over the surface of said at least the portion of the guitar:
applying a mask over the surface of said at least the portion of the guitar by spraying a substantially white radiation-sensitive ink composition over the surface, and exposing the substantially white radiation-sensitive ink composition over the surface to radiation.
12. The method of claim 8 , wherein said applying the decoration over the surface of said at least the portion of the guitar comprises applying the decoration on a curable material of the surface prior to the curable material being completely cured and while the curable material is tacky.
13. The method of claim 8 , further comprising roughening the surface of said at least the portion of the guitar prior to said applying the decoration.
14. The method of claim 8 , wherein said applying the decoration comprises applying a photograph.
15. The method of claim 8 , wherein said applying the decoration comprises applying the multi-colored representation of the digital image over an entire top surface of a body of the guitar.
16. The method of claim 4 , further comprising moving the ink-jet spray nozzle up and down based on the topography of the guitar part in a data file.
17. The method of claim 9 , further comprising using a registration system to register the carrier with the moveable bed, wherein the registration system includes at least one hole and at least one pin to be inserted into the hole.
18. The method of claim 8 , wherein said applying the decoration comprises controlling a volume of the radiation-sensitive ink composition sprayed as dots based on a distance from the ink-jet printheads to the surface of said at least the portion of the guitar.
