Abstract
A method to improve the printing quality of an inkjet printing device for cylindrical surfaces. Specifically, the method will improve the quality of the printed images on the surface of cylindrical objects by iteratively printing and curing the images multiple times, such that even if the outermost layer of ink pigments somehow become smeared and/or removed due to external exposure, the remaining ink pigments below will preserve the printed image's fidelity and legibility.
Claims6
A method for iterative printing for an inkjet printing device for cylindrical surfaces, comprising:
- a. loading a plurality of cylindrical objects to a printing rack;
- b. mounting the printing rack onto a printing platform;
- c. engaging in a first printing process, said printing process comprising moving the cylindrical objects underneath a printing unit to print and dispense ink onto the surfaces of the cylindrical objects to create printed images, followed by moving the cylindrical objects underneath a UV-light source unit to cure the ink;
- d. scanning the printed images to identify ink dots present on the printed images;
- e. assigning a print iteration value for each of the scanned ink dots based on analysis of the scanned ink dots;
- f. repeating the printing process described in (c) on the ink dots that are assigned a print iteration value, by a number of repetitions equal to the assigned print iteration value of said ink dots;
- g. retrieving the printing rack from the printing platform to allow a person to retrieve the printed cylindrical objects.
