Why Should Flexo Printing Machines Have Interstation Drying?
In modern Flexo printing, especially for multi color and high speed applications, interstation drying is a technical feature that is highly recommended.
It plays an important role not only in print quality, but also in maintaining stable machine performance during production.
1️⃣ Control color smearing in multi color printing
In 4-color (CMYK) or extended color printing, ink layers are applied sequentially on top of each other.
If the previous layer has not dried before the next one is printed, it may result in:
- Color deviation from the original design
- Blurred overlapping areas
- Ghosting effects
Interstation drying helps the previous ink layer dry or stabilize immediately after printing, ensuring better color separation and accuracy for subsequent layers.
2️⃣ Maintain image sharpness
High quality flexo printing often involves fine details and small halftone dots.
Without proper drying:
- Ink may spread on the substrate
- Halftone dots can expand
- Image sharpness and fidelity are reduced
Drying between print stations helps fix the ink in place, preserving dot structure and ensuring sharper, more accurate images.
3️⃣ Support stable operation at high speeds
Modern Flexo presses can run at speeds of 300m/min and more
At this level, ink does not have sufficient time to dry naturally.
Without drying systems:
- Print quality becomes inconsistent at higher speeds
- Errors may occur during continuous runs
- Machine speed may need to be reduced
With hot air or UV drying, the ink can dry much faster, allowing the machine to operate efficiently at higher speeds while maintaining print quality.
Interstation drying is not mandatory in every configuration, but it is a recommended technical solution for applications that require:
- Multi color printing
- High print quality
- High speed and high volume production
👍 Investing in the right drying system can significantly improve both print results and long term operational efficiency.
