The systems for processing and preserving products, such as tomatoes, vegetables and legumes, tuna, meat, jams and baby food are located in environments that are very humid and subject to constant temperature fluctuations. Zanasi inkjet marking systems are designed with high standards of protection, suitable for canning and bottling departments and intensive seasonal processing.

In addition, long-life products are subject to heat sterilisation process to maintain the nutritional properties and increase shelf life, i.e. the period of time for which the food product can be safely sold. Thermochromic ink specially formulated by Zanasi to produce codes on materials subject to sterilisation is used to provide quality control indications through the colour change of the ink, which means that the thermal treatment has been carried out in the phase of hermetic packaging.

Zanasi inkjet systems are extremely flexible for marking numerous types of containers with flat, curved, even and uneven surfaces. The versatility of the printhead allows it to be positioned in different points on the production line to clearly code the production data on the side or base of cans made of tin, glass or other materials.


The use of tin cans is one of the longest-lasting preservation methods in the food processing industry.
The inkjet systems have been designed to guarantee clear and precise coding at high speed at all times; a specific request for tin can packaging lines.
In addition, the self-regulation systems maintain the consistency of the performance and efficiency of the Zanasi inkjet range over time, so it can be used in intensive production and continuous changeovers of the different packaging linked to seasonal operations.



Clear glass containers, in different shapes and volumes, are considered to be the best material to display contents and boost purchasing choices, as well as one of the best solutions for the safe storage of food.

The protective barrier is certified by the use of thermochromic inks that guarantee the safety and traceability of the product. Problem-free restarts thanks to a continuous head cleaning circuit, for correct coding of food information with clean and reliable operation.



Cardboard packaging, as a simple tool for logistical and information needs, has assumed an increasingly important role as a vehicle for communication and branding, without foregoing the focus on aesthetics and image uniformity.

To meet the numerous requests for customisation and printing on cardboard boxes, trays and labels, Zanasi offers a complete line of low and high resolution printing systems.

The systems, designed to print text, barcodes, logos and images of different heights, use Drop on Demand piezoelectric printing technology, ensuring robustness and reliability for highly defined high-resolution printing, as well as perfectly traceable, readable and GS1 standard-compliant barcodes, on porous and non-porous surfaces.

The Thermal InkJet range of systems is capable of adhering perfectly to any surface of packaging and multipacks. They incorporate the control unit and ink cartridge, in a small space, allowing the latter to be replaced in a matter of seconds, offering high resolution printing up to 900 Dpi of alphanumeric characters and high quality data matrix.

The wide working range of the heads allows you to take advantage of the entire printing surface available for endless customisation possibilities.

Direct printing of scannable information and barcodes on packaging gives you a real advantage that includes:

– the customisation of the message in real time

– the reduction of storage costs of pre-printed boxes

– the elimination of label costs and related management

– total traceability and identification of products on a logistics level
