What Industries Benefit Most From Using A Continuous Inkjet Printer

Your production line runs at a blistering pace. You need a marking solution that keeps up, printing crisp codes on curved or rough surfaces. Continuous inkjet (CIJ) printers excel at this, making them an essential tool for many companies. We show you how this technology solves complex problems across diverse sectors. Find out if your industry can benefit from this simple, effective coding method.

How CIJ Printing Codes Food And Drinks

Imagine a bottling plant. Thousands of bottles fly past on a conveyor, each one needing a lot number and expiration date. A single smudge or missing code can cause a product recall. It's a constant concern for our industry. Many coding technologies simply can't handle the speed, the condensation on cold bottles, or the moisture in the air. This is where continuous inkjet (CIJ) printing offers a superior solution.

CIJ printers use a unique, non-contact method to place codes. They shoot a steady stream of microscopic ink droplets. An electric charge deflects specific droplets, sending them onto the product in a precise pattern. The unused droplets get recycled back into the system. This method lets us print from a distance, so we never risk damaging the product or interfering with high-speed lines.

We use this technology on a wide array of products. Here's a quick look at some common applications:

● Glass and Plastic Bottles: You see these codes on drinks, sauces, and oils. The biggest challenge here is condensation from cold filling processes. A CIJ printer uses specialized inks that cut through condensation, laying down a durable, fast-drying code that won’t rub off. We can print on the cap, the side, or the bottom of a bottle, no problem.

● Cans and Metal Containers: Think of soda cans, vegetable tins, or coffee containers. Metal surfaces can be greasy from the manufacturing process. The right solvent-based ink ensures the code sticks to the curved surface and dries instantly, preventing any smudging or messy codes.

● Flexible Packaging: This includes bags of chips, pouches of snacks, and candy wrappers. These materials are thin and move a lot. The non-contact nature of CIJ printing lets us mark the packaging without causing any physical stress or tears, even on high-speed flow wrappers.

● Cardboard Cartons: CIJ printers are great for printing lot codes or dates on the outside of cardboard food boxes. The quick-drying ink soaks right in, leaving a permanent mark.

Pharma: Precision Coding For Compliance

Patient safety is not a suggestion. It's the core of the pharmaceutical industry. Every single product must have a clear, accurate code for traceability and brand protection. A smudged date or a missing serial number can put lives at risk. It also exposes a company to massive liability. Because products are often small, with unique surfaces, traditional printing methods simply won’t cut it. You need a system that offers absolute precision and consistency.

CIJ printers bring that necessary precision. They can print codes as small as 0.8 millimeters, making them perfect for tiny vials or the limited space on blister packs. The non-contact printhead means you get a clean code every time, without touching the product. This protects sensitive surfaces and helps maintain a sterile production line. We see this technology as the backbone for compliance and security in the health sector.

Here’s how CIJ works across various pharma products:

● Blister Packs: Individual pill pockets require a lot number and expiration date. CIJ printers can apply these codes with incredible accuracy, ensuring each dose is traceable back to its origin. This is a critical part of modern serialization.

● Vials and Ampoules: These small glass containers often have curved surfaces. The code must be durable enough to withstand sterilization processes, like autoclaving. Specialized inks designed for glass create a permanent code that won’t fade or smear.

● Cartons and Unit-Dose Packaging: This is where you find 2D data matrix codes. These codes hold a lot of information in a small space, including a unique serial number. A CIJ printer can apply these complex codes quickly and clearly on cardboard or glossy surfaces, a key component of tracking and fighting counterfeits.

Wire & Cable: Marking Tough Surfaces

Think about an electrical wire or a fiber optic cable. These products are pulled through walls, buried underground, and exposed to harsh outdoor conditions. The codes printed on them—like voltage ratings, manufacturer names, or safety standards—need to be permanent. They must survive friction, dirt, oil, and water over many years. When a code fades, it can lead to confusion, safety hazards, or a professional installer's nightmare.

Continuous inkjet (CIJ) printers are a perfect fit for this challenge. They are built for the fast-paced, continuous production of wire and cable. The printhead marks a product without ever touching it. This is ideal for soft or uneven surfaces that might be damaged by other printing methods. We trust this technology to provide codes that last as long as the product itself.

Here’s why CIJ is the go-to choice for this market:

● Inks That Stick: Wire and cable jackets are often made from materials like PVC or polyethylene. These materials are slick and resistant to many types of ink. CIJ printers use specialized solvent-based inks. The solvent slightly softens the surface of the cable, allowing the ink to bond and create a code that resists abrasion.

● High-Contrast Codes: Many wires are dark, like black, brown, or blue. A simple black ink code would be impossible to read. CIJ printers offer a range of colored inks, including bright white and yellow, that stand out against dark backgrounds. This high contrast ensures the code is always legible.

● High-Speed Production: Wire extrusion lines run very fast. An off-the-shelf printer simply can't keep up. CIJ printers are designed to synchronize with the line speed, applying clear codes at a rate of hundreds of feet per minute without any quality degradation.

The durability of the code is key. A high-quality CIJ ink is formulated to resist common industrial fluids, like oils, coolants, and solvents. It also handles temperature extremes without flaking or fading. This makes CIJ marking a reliable solution for products used in industrial settings.

Cosmetics: Branding With Codes

When you hold a new perfume or a lotion bottle, the packaging is part of the experience. It feels high-end. But what happens when a messy or smudged code ruins that look? It can damage a brand’s reputation. A coding solution must be both discreet and reliable. It needs to work on a wide variety of materials and curved surfaces without sacrificing the product’s aesthetic appeal.

Continuous inkjet (CIJ) printers are the ideal solution for this. We can print micro-codes, sometimes smaller than a grain of rice, that are barely visible but still hold all the necessary information. The non-contact method means we can print on glossy finishes, textured plastics, or frosted glass without leaving a mark. It’s a way to meet traceability regulations without compromising on the visual quality of your product.

Here’s how CIJ works for beauty and personal care:

● Glass Bottles: Products like nail polish and perfume often come in uniquely shaped glass bottles. A CIJ printer can apply a code to a curved or angled surface with complete precision. The right ink can create a code that is durable and water-resistant.

● Small Plastic Containers: Think of lipstick tubes, mascara, or lip gloss. These products are small and often cylindrical. We can print a code around the side or on the bottom of the container. The ink dries instantly, so it won’t smudge during handling.

● Lotion and Shampoo Bottles: These products are used in wet environments and are handled often. The codes must be able to withstand constant use and moisture without smearing or fading. A CIJ printer with a proper ink delivers a code that will last the product’s entire lifespan.

The personal care industry is all about brand. A clean, well-placed code communicates quality and attention to detail. A smudged or difficult-to-read code tells the consumer the opposite. CIJ technology lets us place the code exactly where we want it, so we can hide it on the bottom of a bottle or keep it small on a cap. This ensures the consumer's first impression is about the beautiful packaging, not the code.
