Mrs Darlington’s Improves Food Coding Reliability with Linx CIJ Printer
Reliable, low-maintenance date and batch coding on glass jars for a leading UK preserves producer.
Mrs Darlington’s produces award-winning jams, curds, pickles and chutneys, with products supplied in the UK and exported worldwide. Printing up to 18,000 jars per day, the company needed a reliable coding solution that could deliver clear traceability codes while reducing the daily cleaning and maintenance required by its previous printer.
The Linx 8940 Spectrum CIJ printer, using opaque blue ink, provided the reliable and consistent coding solution the production team needed.
| Industry | Food & Preserves |
| Substrate | Glass jars |
| Printer | Linx 8940 Spectrum CIJ |
| Application | Date, batch and traceability coding |
| Production Volume | 16,000–18,000 jars per day |
| Outcome | Reduced cleaning, reliable restarts and consistent print quality |

The Challenge
Mrs Darlington’s required clear, high-contrast traceability codes across its range of glass jars.
The production line operates four days per week for approximately 7.5 hours per day, producing between 16,000 and 18,000 jars daily.
Their previous coding system required frequent attention from operators.
Key Issues:
- Daily printhead cleaning
- High maintenance requirements
- Problems restarting the printer after production shutdowns
- Need for consistently clear codes on glass jars
- Requirement for reliable performance across regular production runs
With coding forming an important part of product identification and traceability, Mrs Darlington’s needed a solution that operators could depend on without unnecessary maintenance interrupting production.
The Linx Solution
Mrs Darlington’s installed a Linx 8940 Spectrum Continuous Inkjet (CIJ) printer with opaque blue ink 1043.
The pigmented ink provides strong contrast for codes printed onto the base of the glass jars, while the printer was selected to support the company’s demanding production schedule.
The Solution Provided:
- Linx 8940 Spectrum CIJ printer
- Opaque blue pigmented ink
- Clear coding on glass jar bases
- Reliable operation across regular production runs
- Reduced operator intervention and printhead maintenance
The system gives Mrs Darlington’s a dependable solution for applying clear production and traceability information while helping minimise disruption on the line.

Results & Business Impact
The difference was noticeable after installing the Linx printer.
Since implementation, Mrs Darlington’s has experienced:
- Daily printhead cleaning eliminated
- Significantly reduced maintenance
- Reliable restart after extended shutdowns
- Clear and consistent print quality
- Improved reliability during production
The printer can simply be switched back on when production resumes even after being shut down for several days.
“The old one we had to clean every day, this one we haven’t at all. There’s nothing there to clean. The print is nice and clear. It has been really reliable. It’s consistent, it hasn’t stopped. Its print is perfect.”
Paul Rigby, Production Manager, Mrs Darlington’s
