How Does A CIJ Continuous Inkjet Printer Work

Introduction to CIJ Continuous Inkjet Printers

CIJ continuous inkjet printers are widely used in various industries for coding and marking products with expiration dates, serial numbers, barcodes, and other information. These printers are known for their high-speed printing capability and ability to work on a wide range of substrates. In this article, we will explore how a CIJ continuous inkjet printer works and understand the technology behind its efficient printing process.

Principle of Operation

CIJ continuous inkjet printers work on the principle of projecting tiny droplets of ink onto a substrate to create characters or images. The printer generates these droplets by creating a continuous stream of ink that is broken down into individual droplets using an electric charge. The droplets are then directed towards the substrate through a nozzle, where they form the desired characters or images.

The ink used in CIJ printers is housed in a reservoir, which is heated to keep the ink in a liquid state. The ink is then pumped to the print head, where it is broken down into droplets. A vibrating piezoelectric crystal in the print head causes the ink to break up into droplets of a consistent size. These droplets are then charged based on whether they need to be deflected onto the substrate to create the desired characters or images.

Components of a CIJ Printer

A CIJ continuous inkjet printer consists of several key components that work together to create high-quality prints. The main components include the ink reservoir, print head, charging electrodes, deflection plates, and the substrate where the characters or images are printed.

The ink reservoir stores the ink used for printing, while the print head breaks down the ink into droplets and propels them towards the substrate. The charging electrodes control the charge of the droplets, while the deflection plates guide the droplets onto the substrate to create the desired characters or images.

Printing Process

The printing process in a CIJ continuous inkjet printer begins with the ink being pumped from the reservoir to the print head. The ink is heated to ensure it remains in a liquid state and is then pressurized to create a continuous stream that is broken down into droplets by the piezoelectric crystal in the print head.

Once the droplets are formed, they pass through the charging electrodes, where they are selectively charged based on the characters or images that need to be printed. The deflection plates then guide the charged droplets towards the substrate, where they form the desired characters or images. The entire process is repeated multiple times per second to create continuous printing.

Advantages of CIJ Printers

CIJ continuous inkjet printers offer several advantages over other types of printing technologies. One of the main advantages of CIJ printers is their ability to print on uneven or curved surfaces, making them ideal for a wide range of substrates.

Additionally, CIJ printers are known for their high-speed printing capabilities, allowing for efficient coding and marking of products in various industries. The printers are also cost-effective, with low operating costs and minimal maintenance requirements.

Summary

CIJ continuous inkjet printers are a popular choice for coding and marking products in various industries due to their high-speed printing capabilities and ability to work on a wide range of substrates. The printers operate by projecting tiny droplets of ink onto a substrate to create characters or images, with the ink being broken down into droplets and charged before being directed towards the substrate.

The key components of a CIJ printer include the ink reservoir, print head, charging electrodes, deflection plates, and substrate. The printing process involves pumping ink from the reservoir, breaking it down into droplets, charging the droplets, and guiding them onto the substrate to create the desired characters or images.

Overall, CIJ continuous inkjet printers offer several advantages, including the ability to print on uneven surfaces, high-speed printing capabilities, and cost-effectiveness. These printers play a crucial role in the coding and marking of products, ensuring accurate and efficient printing for various industries.
