What does a coding system do?

By means of industrial printing, or coding, you apply information such as text and numbers to a product or packaging. Multiple terms are used for this process, such as coding, printing or marking.

There are different ways of coding and printing has different applications and purposes. You can read more about these goals and applications below.

Why use an industrial inkjet printer?

Information is transferred by printing with coding systems. This makes it possible to provide information directly to the user. For example, the best before date can be printed, but also contact details on a shipping box, or user instructions on a product or box.

Products can also be made recognizable by coding. Barcodes, QR codes or type numbers can improve the recognisability of individual products, boxes or pallets. These can all be printed with an industrial printer.

Making a product traceable is an important goal of industrial inkjet printing. Think of coding batch codes, production data and other track & trace information on products. This information is important for manufacturers, but it does not in itself provide information.

How does industrial printing with a coding system work?

Coding of products and packaging can be done in several ways. The Cyklop industrial inkjet printers can be divided into two technological categories: High Resolution Inkjet printing and Continuous Inkjet printing.

A high resolution inkjet printer (or coding system) can be used well when high print quality and ease of use are important. It is no problem to print 2D codes, barcodes, expiry dates (best before date), texts and logos in high resolution. The industrial printing with the coding system can be done on almost any surface with the right combination of industrial printer and ink.

Continuous inkjet printers (or small character inkjet printers) are designed to code on almost any type of material, often at high speed. Industrial printing is possible regardless of porosity, size, shape and texture. It is also no problem to print information such as best before data, text, batch codes and logos on individual products with our coding systems.

High Resolution Inkjet printing

High resolution inkjet printers use standard cartridges and do not require additional solvents. Replacing cartridges on the coding system is very easy, and generally wiping the printhead and cartridge is the only maintenance that the coding system needs. The industrial inkjet printers work by heat in the printhead. The ink is heated when something needs to be printed, causing it to expand. The ink is then ‘ejected’ through the openings (nozzles) in the printhead of the industrial printer. For best results, the industrial printer should be placed close to the product due to the limited flow distance of the ink.

Advantages of the high resolution inkjet printer:

• Excellent print quality on almost any surface
• Maintenance is easy
• User friendly
• Use of cartridges
• Easy to integrate in an automatic line or in / on packaging machines

Continuous Inkjet printing

Continuous inkjet printers use ink and make-up liquid (thinner). Both liquids are in a separate container / bottle in the coding system and are mixed in the ink reservoir to achieve the correct viscosity. The ink is fed from the ink reservoir into the print head under high pressure via the print hose. This head contains a resonator, an electronic element, which causes vibrations in the ink jet. This creates droplets, which are necessary for printing, which then leave the print head. In combination with the movement of product or printhead, a legible coding is applied to the material. The unused drops are returned to the reservoir in the industrial printer via a return line, so that no unused ink is lost.

The main advantages of continuous inkjet printer:

• Suitable for coding on uneven surfaces
• High speed printing
• Contactless coding, longer distance to product is possible
• Change ink and make-up separately and easily
• Low cost per print

Which method of industrial printing is most suitable?

Choosing the right inkjet printer is not always easy. Shape, print environment, speed, type of surface, what to print and the conditions to which the print is exposed play a role in making this decision.

We would of course like to help you with making a decision on which coding system meets your needs! Please feel free to contact us for tailor-made advice.

Consumables for our coding systems

When printing with a high resolution inkjet printer, two types of ink are used: solvent ink and water-based ink. Solvent ink is suitable for printing on non-absorbent or non-porous materials such as plastic, metal and glass. Water based ink is suitable for printing absorbent or porous materials such as paper, cardboard and wood.

Fast drying ink and make-up fluid are used when coding with a continuous inkjet printer. Both liquids are in a separate container that can be replaced separately.
