Continuous Inkjet


We are all familiar with continuous inkjet printing (CIJ), whether we know it or not. It is a vital part of the labelling industry. You can find it in use on eggs, bottles and all kinds of other everyday packaging, as well as on components for car production and cables.

Why? It is a quick and precise way to label products with low ink consumption.

Continuous inkjet - contact-free printing technology

It is a quick and precise way to label products with low ink consumption. Continuous inkjet printers (CIJ) are especially frequently used in industrial contexts, where they use tiny droplets of ink to create high-quality printed images. And they don’t even come into contact with the material they are printing. The droplets of ink are carried through the air for distances ranging a couple of millimetres to several centimetres. The precision of this kind of technology lends itself to a whole range of commercial uses on almost any surface: packaging, bottles, car components... High-performance labelling systems often use CIJ printers from leading brands like Hitachi.

CIJ printers – manufacturers and models

Here, you will receive high-performance solutions from continuous inkjet manufacturer Hitachi. The Hitachi UX and Hitachi RX2 models guarantee seamless and efficient production processes. They provide solutions that are the perfect fit for diverse companies and industries.

Hitachi RX2

The Hitachi RX2’s continuous inkjet process is the perfect solution for diverse product labelling needs.

This versatile range comprises one printer model that can be adapted for several functions using a two-step configuration process. The options available are specifically targeted towards customers with changeable printing needs.

Hitachi UX2

The new Hitachi UX2 continuous inkjet printer just keeps going and going. A host of new features have been incorporated to keep downtimes to a minimum.

The improved print head stops dirt from getting in where it shouldn’t, while a guard electrode ensures that you can carry on printing constantly – with top-quality results.

Hitachi UX

Hitachi is a manufacturer with a long tradition and the Hitachi UX is their response to modern needs in a digital industry.

This printer provides top-class printing quality and the precision you expect for industrial use. The range contains nine different models, from entry level to high end.

Continuous inkjet:

Continuous Inkjet (CIJ) printers are commonly used in a variety of industries, including food and beverage, pharmaceuticals, and electronics, to print product information and codes on packaging and other materials.

The case studies we have collected here highlight how useful contact-free printing technology can be in industrial processes. Continuous inkjet printing is used when bar codes, 2D codes, OCR, expiry dates, batch numbers or consumer information need to be printed onto packaging or other products automatically.

Continuous inkjet (printing) processes guarantee a high-quality image on the base material. Products and packaging to be printed can be made from almost any material, e.g. paper, cardboard, foil, glass, plastic or metal.

In short, continuous inkjet is suited to high-quality, efficient and economical product labelling in trade and the packaging industry.

Continuous inkjet – more benefits than industrial printers

Continuous inkjet is a technology which presents many advantages. Contact-free printing, incredible speed and low ink consumption are all noteworthy. The ink droplets are electrostatically charged and can be steered incredibly precisely at lightning speed, meaning any possible print content can be produced, even if it changes regularly. No difficult retooling has to be carried out to change the information or shapes being printed.

Continuous inkjet – the right inks for your printer

CIJ inks are specially formulated to create high-quality, durable prints on various surfaces, including plastic, metal, and paper. Available in a range of colors and formulations, these inks are critical for ensuring the quality and durability of the printed output in the CIJ printing process. Here you can find the perfect inks for your continuous inkjet printer.

The advantages of continuous inkjet

Continuous inkjet printing facilitates contact-free labelling because the ink droplets are guided through the air to the surface being printed.

This means that the continuous inkjet printing method can even print uneven or delicate surfaces with great precision. Major advantages of continuous inkjet printing include versatility, high item numbers printed and the printers’ capacity for continuous operation.

In contrast to other technologies, the high printing speed means it is possible to print materials that move quickly. Even speeds of several metres per second are no problem for high-performance continuous inkjet printers.

While techniques like gravure and offset printing require a set image to print, continuous inkjet is able to handle different images and information in sequence. Whether you require graphics, text, codes or numbers – everything can be achieved in a short time and with no retooling, so long as you have the right file in your database.

The CIJ process works with high data density and precision, providing a particularly effective alternative to traditional labelling systems. That is why this method is so widely used in the consumer goods industry.

Depending on the special inks used, the coding works for almost any surface, including dark surfaces.

Precise printing of very small print is no problem and neither is large text.

In comparison to other technologies, printing costs are lower. Value for money.

Frequently asked questions regarding continuous inkjet technology

Still have questions? You can find more detailed information here.

The term ‘continuous inkjet’ describes a modern printing technology which does not require contact with the surface being printed. Instead, the materials to be printed are simply moved past the print head on the CIJ printer on the production line. The printed image is created by targeting and steering tiny ink droplets using physics.
