Abstract: A method for efficiently printing an article by using a UV ink-jet printer and a printing module for implementing the method are disclosed and characterized in that at least one of a color-ink and an assigned-color-ink printheads is connected with a movement-controlling mechanism which manages to move the printhead for a certain distance on the printing module. The article will be printed after the printhead is moved apart from its original location so that the article can be efficiently printed whether the color-ink or the white-ink printhead is to be utilized first.
