Bottle Printing with Pyrosil® Treatment & UV Cylindrical Curing

Nazdar rigorously tests all inks for top performance from application to end use. For bottle printing, Nazdar technicians take the following steps to ensure inks are adhering and performing to high quality standards:

1. The bottle is treated with Pyrosil®, a silicone treatment applied via flame, to create a microscopic silicate coating on the substrate. This increases surface energy and, in doing so, improves ink adhesion. For more information on Pyrosil®, check out our last Nazdar Tech Tip.
2. Ink is then printed onto the bottle. The demonstration above shows Nazdar 2300 Series Ink, a versatile ink that can be cured with UV-LED or traditional UV light and has been formulated to meet the processing requirements of the container printing industry.
3. To cure, the bottle is placed into the Systematic Automation's Model UVSP. This UV-LED curing unit is specifically designed for cylindrical objects—typically a difficult shape for units to handle. The plate on which the bottle is placed rotates 360° when in front of the UV LED light. Because this method does not require mirrors, which degrade UV LED light and can lead to curing inconsistencies, the ink is uniformly exposed to the UV LED lamp, ensuring consistent cure.
