Continuous inkjet printers have been occupying an important position in the inkjet coding industry because it can print on flat and curved surfaces, and has the advantages of high work efficiency and low cost of consumables. Traditional CIJ printers mainly print production date, expiration date, batch number and LOT number, and also focus on printing speed and stable printing quality. With the development of coding and marking industry technology, the new CIJ printer can now print variable data, QR codes, etc. MEENJET has developed new models of CIJ inkjet printers, offering reliable, high-quality marking and coding solutions for your packaging and products.
Continuous inkjet printing technology is a non-contact printing method that can utilize a range of continuous inkjet inks to print on almost any substrate, both flat and curved surfaces.
In simple terms, continuous inkjet printers emit a constant stream of tiny, fast-drying ink droplets. Some of these droplets are electrically charged and are redirected by an electrostatic field to a nearby surface to create text, dates, logos, barcodes, or other prints. The remaining uncharged droplets are recaptured and recycled back into the printer. They have another name: "small character inkjet printers", indicating the print information sizes.
Due to its advantages of high-speed coding and low-cost maintenance, CIJ inkjet printers have been widely used in industrial and commercial applications.
Every day in the world hundreds of CIJ printers are used to print required information on thousands of individual packages for various industrial applications. Here are some examples where CIJ inkjet printers are used:
In the food and beverage, and pharmaceutical and cosmetics industries, they can print expiration dates, lot numbers, and use-by dates on snack packaging, frozen food films, condiment containers, pharmaceutical and cosmetic bottles, as well as pudding, yogurt, and jelly cups filled by a cup sealer or deep-drawing packaging machine. When integrated into the production and inspection lines, CIJ printers are also employed for defect marking based on inspection machine results, such as for wafers, PCBs, and films in electrical machinery and electronics industries.
In the automotive industry, CIJ printers capable of non-contact can print on curved surfaces like mufflers and aluminum wheels. They are ideal for marking plated or painted parts to prevent corrosion, using white or yellow ink for black-painted surfaces like undercarriage parts. Additionally, CIJ printers are crucial for printing on extruded pipes and hoses, offering consistent, high-quality marking during continuous production without smudged or incomplete characters.
CIJ printers can print on various material surfaces, from carton boxes, glass bottles, plastic bags, wood to stainless steel. They can commonly print on almost any substrates when choosing the right ink. Here are some key factors for surface suitability:
Ink Compatibility: CIJ printers can use a variety of inks, including solvent-based, UV-curable, or water-based inks, depending on the surface material.
Surface Texture: CIJ printing works well on both smooth and rough surfaces, though the quality of print may vary depending on how porous or textured the material is.
Durability Requirements: CIJ printers are well-suited for surfaces that need durable markings, such as products exposed to harsh environments (e.g., automotive parts or industrial products).
The best way to determine whether the CIJ printer and ink are suitable for you is to print samples on your package or products. MEENJET has provided sample printing services for customers in multiple industries. We can send you some samples as you need.
MEENJET CIJ printers are built to seamlessly integrate into most industrial production lines, with a variety of accessories designed to support this. These printers need to operate as part of the broader production process, aligning with other equipment on the line. The available accessories include software, brackets, and mounting solutions that allow CIJ printers to be positioned at various angles to the production line. Given that these printers are often installed in tight spaces, flexibility in installation is a key feature.
High-Speed Printing: Capable of printing on fast-moving production lines without compromising quality, suitable for high-volume operations.
Non-Contact Printing: The ink is sprayed onto the surface without direct contact, enabling printing on delicate, irregular, or curved surfaces.
Versatile Substrate Compatibility: Can print on a wide range of materials, including plastics, metals, glass, paper, wood, and rubber.
Continuous Operation: Designed for long periods of uninterrupted operation, ideal for 24/7 manufacturing environments.
Ability to Print Small Characters: Can produce high-resolution text, graphics, and barcodes limited to one to six lines of text, even in very small sizes, for detailed marking requirements.
Efficient Ink Use: Unused ink droplets are recirculated, reducing waste and enhancing cost efficiency.
Dynamic Printing Capabilities: Can print variable data such as dates, batch codes, barcodes, and serial numbers in real-time, based on inputs from connected systems or inspection machines.
Environment and Surface Adaptability: Performs well in challenging environments (e.g., dusty, humid, or high-temperature conditions) and can adapt to substrates with varying surface textures or coatings.
Wide Ink Color Options: Inks are available in multiple colors, including specialty inks like white, yellow, or UV-reactive for specific applications.
Compact and Flexible Design: CIJ printers are typically compact and easy to integrate into existing production lines, even in limited spaces.
Low Maintenance Requirements: Modern CIJ printers include automated cleaning systems, minimizing downtime and ensuring consistent performance.
