- What is the difference between labeling and coding?
- A labeler applies a physical label — pressure-sensitive, sleeve or roll-fed — to the pack. A coder prints a date, lot or barcode directly onto the pack or label using CIJ, thermal transfer or laser. Print-and-apply systems combine both in one station.
- Which coding technology should I choose?
- CIJ is the workhorse for high-speed date and lot codes; thermal transfer (TTO) gives a crisp, durable code on film and labels; laser needs no consumable ink and suits permanent marking. The choice is driven by what the code must survive — scuffing, condensation, freezer or retort — and the substrate.
- How do I choose a labeling machine?
- Specify the container, surface and line speed, then match the technology — a pressure-sensitive labeler for flat packs, a sleeve labeler for shrink decoration, or a roll-fed labeler for high-speed round bottles. Confirm label and machine are qualified together.
- What are the running costs of coding and labeling?
- CIJ ink and make-up, thermal-transfer ribbon and label stock are recurring costs that dwarf the machine price over its life. Quote consumables together with the machine, not separately.
- Which label application method should I use?
- Pressure-sensitive (self-adhesive) suits flat and shaped packs with high placement accuracy; sleeve labeling gives 360-degree shrink decoration and tamper evidence; roll-fed (wrap-around) is the lowest cost per label for high-volume round bottles.
- How fast do labeling and coding machines run?
- Self-adhesive applicators run from tens to hundreds of labels per minute, roll-fed labelers reach tens of thousands of containers per hour, and CIJ coders print at hundreds of metres per minute. Always validate on your container and surface, not the brochure figure.
- What makes a code or label durable enough?
- The substrate and the code life decide the technology — CIJ ink can be removed by solvents, TTO gives a crisp durable code on film, and laser etches a permanent mark. Test adhesion and scuff resistance on your actual pack and distribution chain.
- Do I need a labeler, a coder, or both?
- If the pack carries a pre-printed label, start with the labeler; if it needs a date, lot or barcode, start with the coder. A line with both needs both — often a print-and-apply system bridges labeling and coding.
