Serialization refers to the process of imparting variable information to a security hologram or label, so as to make it unique in nature. This information may be in the form of barcodes, QR codes or serial numbers which can be read by field personnel using handheld devices or even by the end customers using our mobile application.

Serialization has become a fundamental part of the production and logistics operations of many manufacturers across various industry sectors. Its implementation has led to a significant curb in the circulation of counterfeit products throughout distribution channels, thus greatly increasing consumer trust and loyalty for brands worldwide.

There are many techniques used for serialization, and choosing the right one depends on the application, material and how well it integrates with other equipment in the production process. It is critical that the printing process has the ability and speed necessary to meet production demands.

Serialization Techniques

Inkjet Numbering

The variable codes are printed on to the label or hologram using inkjet technology. This technique is suitable for a variety of packaging & label types such as unvarnished labels, cartons, blister foils or pouches etc. Best results are obtained when the printing is done along the direction of the label. We use high quality fluid based non contact inkjets which are capable of printing via conveyor systems.

Thermal Printing

This type of printing is suitable for varnished, laminated or clear labels and holograms. A digitally controlled print-head precisely melts ink from a ribbon directly onto the substrate to provide high resolution, precise prints.Different types of ribbons are used for different substrates. Unlike inkjet printing, this type of serialization can be done in any orientation, i.e. along or perpendicular to the label or hologram. Thermal printing is known for its high precision and quality, resulting in very low rejection rates.

Laser Etching

As the name suggests, laser etching is simply creating markings on a substrate by using a controlled laser beam to remove material from its surface. The biggest advantage of laser etching is that it can be used on any surface including holograms, metals, glass, ceramics, plastics, wood and various other product packaging materials. The USP of laser etching is its permanence i.e. it cannot be removed in any way.

UV Numbering

UV Numbering refers to the process of printing variable serial numbers, alpha-numeric codes, QR codes which are invisible to the naked eye. The printing is visible when exposed to UV light. This type of printing of variable information is particularly useful in the prevention of illegal inter-state transfer of goods.

Overprinted Holograms

In printing terminology, overprinting refers to the process of printing any data on top of another printed substrate, which could be a hologram, label or any other packaging material. This process is commonly used in food packaging to print information such as manufacturing / expiry dates, batch codes etc.

Veritech has implemented this technique in serialization processes, wherein the barcode, QR code or serial number is printed on top of generic or customized holograms. in addition to the serial codes, it is also possible to print the brand logo or any other text / image as per the clients’ requirements on top of the hologram.
