Fine-line security ink for detailed guilloche work
Guilloche Security Ink is formulated for packaging that needs crisp interlocking curves, fine lines and repeatable detail. It is used where a package must look refined on the shelf while also carrying a security feature that is harder to copy by eye or by simple scanning. The ink can be set up as a stand-alone protection layer or combined with other security elements in a packagng specification.
This product is suited to short-run premium cartons, export packs, limited editions and regulated goods where authenticity matters. In Durban and across South Africa, we see it used on pharmaceutical outer packs, cosmetic cartons, speciality food packaging and high-value consumer goods. The ink can be tuned for different line widths, contrast levels and substrate behaviour, so the guilloche pattern remains readable after folding, die-cutting and handling.
- Fine-line pattern control for intricate guilloche designs
- Suitable for premium packaging and anti-copy features
- Can be matched to existing artwork systems and production limits
- Works on a range of coated and uncoated packaging substrates
Sizes, formats and colour options for converter lines
We supply Guilloche Security Ink in production-friendly formats for packaging converters. Standard supply is in 1 kg, 5 kg and 20 kg containers, with trial quantities available for press testing and approval runs. For converters running repeated programmes, retain samples and batch records can be held in our library so future reorders stay consistent.
Colour choice depends on the security effect you want. Some customers prefer high-contrast black, blue or red patterns for easy visual checking. Others ask for low-visibility tones that only show clearly under the right viewing angle or inspection setup. The ink can be adjusted for opacity, line sharpness and drydown so the finished result supports both shelf presentation and verification at line level.
- 1 kg, 5 kg and 20 kg packaging options
- Trial batches for artwork approval and press setup
- Custom colour matching to existing pack systems
- Batch retain records available for repeat production
Where Guilloche Security Ink suits best
This product suits packaging that needs a premium appearance with built-in authentication. It is commonly specified for consumer packs that pass through several hands before sale, where the customer, retailer and distributor all need confidence that the item is genuine. Because the lines are detailed and patterned, it also helps if a pack is opened and repacked, since the print can act as a reference point during inspection.
It performs well on folding cartons, paperboard sleeves, secondary packaging and selected label stocks, provided the substrate and finishing process are checked first. For coastal areas like Durban, Richards Bay and Gqeberha, we also look at humidity, storage conditions and the way the pack will sit in transit. If cartons are stored near loading bays or in warm warehouses, the ink and coating combination must be chosen carefully so the print stays legible and the bond remains firm.

- Cosmetics, fragrance cartons and premium retail packs
- Speciality food packaging and export-ready cartons
- High-value inserts, sleeves and authentication panels
Press setup, drying and production requirements
Guilloche Security Ink is meant for normal packaging production lines, so it does not need special gas supply or unusual power installations. Standard electrical power for the press, drying unit and ancillary equipment is usually sufficient. Where a converter uses heat-assisted drying, the set-up should be checked against line speed, substrate weight and ambient conditions. In many South African plants, load-shedding planning also matters, so press teams should confirm backup power for critical drying and inspection stages.
For best results, the ink should be trialled before full production. We support drawdown panels, adhesion tests, rub resistance checks and UV verification setups where required. On press, the main points are ink film consistency, drying time, anilox or plate compatibility and how the guilloche lines respond to pressure. A clean fountain, calibrated system and stable room conditions make a real difference to line clarity.
- No special gas supply required
- Standard electrical power is normally adequate
- Drying setup should be matched to substrate and speed
- Backup power planning recommended for critical lines
Care, storage and ongoing servicing
Security ink should be stored in a cool, dry place away from direct sun and heat sources. Keep containers sealed when not in use and mix thoroughly before production. If the same product is held for repeat jobs, label the batch clearly and record the date opened, so the production team can track stock age and rotation. This is especially important in humid coastal conditions where moisture and temperature swings can affect performance.
Our team can assist with production troubleshooting if line detail starts to drop, if the pattern looks soft, or if drying is inconsistent across the sheet. We also help with coating compatibility checks when a converter changes varnish, laminate or board grade. If a customer wants longer-term control, we can keep reference samples and verify the pattern against the original specification on later runs.
- Store sealed in a cool, dry area
- Keep away from direct sunlight and hot plant zones
- Use batch labels and retain samples for repeat work
- Review coating and board changes before production
What to check before you place an order
When ordering Guilloche Security Ink, it helps to have the print method, substrate, final pack size and security goal ready. Tell us whether the pack is for visual authentication only, for line inspection, or for a broader anti-counterfeit system. If you already have an artwork layout, we can review the line widths and advise whether any threshold tuning is needed for sharper definition.
It is also worth confirming drying method, target run speed and whether the job will be printed in Durban, Johannesburg, Cape Town or another converter site. If the pack has to travel through hot inland routes or coastal humidity, the choice of coating and storage window should be included in the brief. For first-time jobs, we usually recommend a trial batch and press startup support so the line team can confirm performance before the main run.
