Inkjet coding guide

questions before buying a date coder

A good enquiry gives the supplier enough information to recommend the correct technology and avoid a poor fit.

Industrial inkjet coder installed on a packaging line
What to check first

Check the pack, code and production line before choosing the printer

Questions to answer before buying a date coder for bottles, cartons, pouches, labels or packaging lines.

The right recommendation depends on the material, print area, expected contrast, dry time, production speed and how operators will change messages. Lancing can look at your sample pack and advise whether CIJ, TIJ, large character or handheld inkjet is the best fit.

Print content

Date, batch, lot, expiry, serial number, barcode, QR code or simple product identification.

Pack surface

Plastic, glass, metal, carton, label, sleeve, pouch, tray, sack, case or coated packaging.

Line details

Speed, printhead position, product sensor, encoder, brackets, guards and operator access.

Need this on a live line?

Send the pack type, code example, line speed and available space. We can suggest the best coding route before you commit to a machine.

Where it fits

Typical production requirements

These pages are written around real packaging problems: substrate, line speed, print position, operator changeover and traceability content.

Pack details

Material, shape, print area, label or direct print, and whether the pack is dry or handled soon after coding.

Line details

Speed, product spacing, conveyor movement, guarding, operator access and available mounting space.

Code details

Number of lines, date format, batch or lot content, barcode or QR size and data source.

Questions

Common questions

Can this type of inkjet coder print dates and batch numbers?

Yes. The usual print content is a date, batch number, lot code, expiry date, barcode, QR code or production reference. The best technology depends on the pack surface and line speed.

Will the code dry on plastic, glass or film?

Ink choice and print position matter. A sample pack check helps confirm contrast, adhesion and dry time before installation.

Can a coder be fitted to an existing packaging line?

Most installations can be designed around an existing conveyor or machine using brackets, sensors, encoders and practical guarding access.

Ask Lancing to recommend the right coder.

Commercial and technical questions

Questions that make date-coder quotations comparable

Ask suppliers to answer against the exact application and configuration. A maximum figure from a brochure may not apply to the selected font, ink, number of lines or environment.

Machine capability

  • What print height, lines and resolution apply at our line speed?
  • What is the permitted throw distance and product-position tolerance?
  • What enclosure or IP rating applies to the complete installation?
  • Which codes, fonts and communication protocols are included?

Ink and consumables

  • Which exact ink or cartridge is approved for our substrate?
  • What dry time and resistance were achieved in the sample trial?
  • What assumptions support the quoted running cost?
  • What storage, shelf life, ventilation and waste controls are required?

Integration and quality

  • Who supplies the sensor, encoder, brackets, guarding and line I/O?
  • How are jobs selected and variable records downloaded?
  • How are missing, wrong or unreadable codes detected?
  • What happens on printer, network or reject failure?

Support and acceptance

  • What is included in installation, commissioning and training?
  • Which scheduled service parts and licences are required?
  • What spares and response route are available?
  • What factory and site acceptance tests will be recorded?

Ask for exceptions and assumptions

Require the quotation to identify anything not included: conveyors, extraction, network work, PLC changes, vision, reject equipment, guarding, validation, product samples, travel, consumables or production support. Clear boundaries are part of a technically useful price comparison.
