About FLYSECURE
FLYSECURE concentrates add authentication features to standard packaging and label inks without changing the printing process. Each feature is supplied in the FLYCURE NANO UV vehicle (suffix -UV) or the FLYCRYL water-based vehicle (suffix -WB), so it can be let down into the customer’s own ink or varnish and printed on an existing station.
Typical properties of the range
| Property | Typical value | Method |
|---|---|---|
| Feature pigment content | 5–40 % (grade dependent) | Formulation |
| Viscosity at 25 °C | 1,000–4,000 mPa·s | Brookfield |
| Invisibility of UV marks | ΔE ≤ 1.5 against the unprinted white substrate (target) | CIELAB, D65/10° |
| IR pair visual match | ΔE ≤ 2.0 between IRA and IRT prints (target) | CIELAB, D65/10° |
| Light fastness of UV marks | Organic types limited (indoor); SC-UVR high | Xenon exposure |
Values for the FLYSECURE range; the certificate of analysis for SC-TC gives the release values.
How to use
- Let-down
- UV-fluorescent features 5–20 % in ink or varnish; IR pair used as the black of a matched design; SC-TC 20–30 % in a water-based varnish
- Substrates
- Invisible marks read best on substrates without optical brighteners; on OBA-containing board use green or red features
- UV curing
- Fluorescent pigments absorb part of the curing UV: confirm full cure at the intended level and speed
- Design
- Combine two features (for example SC-UVR with an IR pair) for layered protection
