Abstract
An ink injection method includes the steps of: storing vibration region information of a stage to which a head for injecting ink is mounted; changing coordinates of the stage by deducting the coordinates as much as the vibration region in a direction opposite to a pattern printing direction on the basis of coordinates at which pattern printing starts; moving the stage in the pattern printing direction after the stage is moved to the changed coordinates; deducting the changed coordinates from current coordinates of the stage to calculate a moving distance of the moving stage; and controlling the head to inject ink in correspondence to the pattern in case the moving distance of the stage is corresponding to the vibration region. This method prevents erroneous pattern printing due to initial vibration caused by movement of the stage when ink is injected for printing the pattern.
