Abstract: Apparatus and methods of decorating guitars and other stringed musical instruments are disclosed. In one aspect, a method may include UV printing a first portion of a decoration over a first region of at least part of a guitar using a first ink drop size, and UV printing a second portion of the decoration over a second region of said at least part of the guitar using a second ink drop size. In another aspect, a method may include UV printing a mask layer over a surface of at least a portion of a guitar using a first amount of image constriction and a first amount of feathering, and UV printing a decorative layer over at least a portion of the mask layer using a second amount of image constriction and a second amount of feathering.

Abstract: 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.
