PRINTING DEVICE AND PRINTING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18534783 titled 'PRINTING DEVICE AND PRINTING METHOD

Simplified Explanation: The patent application describes a method for controlling a printing device when defective nozzles in a printer are detected to be adjacent to each other in a sub-scanning direction.

When a transport unit moves by a predetermined distance, the printing device adjusts the movement distance before the defective nozzles discharge ink to ensure proper printing.
The adjustment can involve changing the movement distance by an integer multiple of the nozzle pitch to avoid printing errors caused by the defective nozzles.

Key Features and Innovation:

Control of movement distance of the transport unit based on the position of defective nozzles.
Adjustment of movement distance by an integer multiple of the nozzle pitch to prevent printing errors.
Ensuring proper printing quality despite the presence of defective nozzles.

Potential Applications:

Inkjet printers
Large format printers
Textile printing machines

Problems Solved:

Preventing printing errors caused by defective nozzles
Maintaining print quality in the presence of nozzle defects

Benefits:

Improved print quality
Reduced wastage of ink and materials
Enhanced reliability of printing devices

Commercial Applications: The technology can be applied in various industries such as advertising, packaging, and textile printing to ensure high-quality output and minimize production costs.

Prior Art: Prior art related to this technology may include research on nozzle defect detection and correction in printing devices.

Frequently Updated Research: Stay updated on advancements in inkjet printing technology and defect correction methods to enhance the efficiency and accuracy of printing processes.

Questions about the Technology: 1. How does the adjustment of movement distance improve print quality in the presence of defective nozzles? 2. What are the potential cost-saving benefits of implementing this control method in printing devices?

Original Abstract Submitted

In a case in which a dot of a first raster line to be discharged by a first defective nozzle and a dot of a second raster line to be discharged by a second defective nozzle are determined to be adjacent to each other in a sub-scanning direction when a transport unit performs movement by a predetermined first distance, a printing device performs first control of executing either control of changing a distance of the movement performed by the transport unit immediately before the first defective nozzle forms the first raster line by an integer multiple of a nozzle pitch from the first distance, or control of changing a distance of the movement performed by the transport unit immediately before the second defective nozzle forms the second raster line by an integer multiple of the nozzle pitch from the first distance.
