Rotech’s experience of coding and marking technologies covers everything, from traditional hot foil stamping to the latest innovations in inkjet and thermal transfer.

Adding variable information to products late in the production cycle is a critical process, especially within pharmaceutical and food industries, where traceability and security is an essential part of supply chain management.

Whilst maintenance-free Thermal Inkjet (TIJ) technology is Rotech’s most popular coding and marking solution, we are able to supply and support other coding and marking technologies.

Thermal transfer

Ideal for applications that require a large amount of information to be printed, particularly on flexible film and medical paper.

A print is made by placing thermal transfer ribbon between a heated printhead and the product to be marked. The heat passes through the ribbon, releasing the ink, which adheres to the substrate, cooling rapidly, resulting in a permanent print.

Thermal Transfer overprinting (TTO) coders are suitable for printing high quality variable data, barcodes and images onto packaging material, for a wide range of industries.

Versatile

Hot foil

Ideal for the printing of discrete LOT identification onto cosmetic cartons.

Hot foil technology is reliable, economical and low maintenance, making it ideal for printing use by dates, lot numbers, batch codes and expiry dates. It is also versatile in that it can print metallic codes – something the other technologies cannot do.

It works by a heated metal die pressing a pigmented hot foil tape against the packaging material.

High Resolution

Durable

Low initial cost

Laser

Ideal for the identification and product verification of pharmaceutical cartons

An environmentally friendly technology, laser printers work by etching or vaporising the surface layer of the material, leaving an inerasable mark.

Scribing laser coders can produce text, graphics, variable and serialised data as well as 2D codes onto a range of substrates, including cartons.

Cost-effective

Environmentally friendly

Continuous Inkjet

Ideal for fast moving lines, such as bottling lines.

Continuous inkjet printers, as the name implies, create a continuous stream of charged ink droplets.

While sophisticated, these types of printers require careful maintenance and are also limited in their resolution, as only one droplet lands on the product at a time.

The solvents employed can also present a challenge in terms of safe disposal. Care should be taken to avoid product contamination.
