Method and arrangement for printing a three-dimensional surface

摘要

A method of printing includes using a printing head that comprises straight parallel rows of printing nozzles to print a printed image on a surface of a conically rotationally symmetrical region of an outer wall of an object by controlling parallel rows of printing nozzles taking into account pixel density to be achieved in the printed image, setting a printing density of a printing nozzle with regard to at least one reference parameter, and setting a variable offset between a pair of the rows based on a change in relative speed between the printing head and the conically rotationally symmetrical region of the object.

1. A method of printing on a conical portion of an object, said method comprising using a printing head that comprises straight parallel rows of printing nozzles to print a printed image on a surface of a conically rotationally symmetrical region of an outer wall of said object, wherein said conically rotationally symmetrical region is specified by a cross-section, wherein said cross section is defined by an array of three parameters of said object, wherein using said printing head to print comprises controlling said parallel rows of printing nozzles taking into account pixel density to be achieved in said printed image, setting a printing density of a printing nozzle with regard to at least one reference parameter, and setting a variable offset between a pair of said rows of nozzles based on a change in relative speed between said printing head and said conically rotationally symmetrical region of said object.
