Important information for optimal performance

Spring’s FLUO is not suitable for printing direct thermal papers. It is always recommended to test compatibility between ink and substrate.

Our FLUO system is unique in that it is a one-pass ink. However, for maximum fluorescent effect, one may apply two hits with an anilox of 10-14 cm3/m2. For greater gloss and resistance properties, Spring’s ink ranges are fully compatible with our UV varnish systems.

Care should be taken with fluorescent inks as their drying speed is generally slower than that of standard inks. Water based fluorescent inks are pH sensitive; only use additives approved for use with the FLUO range. See our Technical Data Sheet concerning Ink Additives for more detailed information.

The shelf life of these inks is limited to three months from date of manufacture, provided the inks are stored in a cool, dark location, protected from freezing.

Fluorescent pigments have poor light resistance and are not recommended for packaging which will be exposed to sunlight.

In general, water-based fluo systems provide higher fluorescent effect than UV systems as UV lamps tends to degrade fluorescent pigments.
