Hidrostar: High-Opacity Water-Based Ink
General Description
Hidrostar is a series of water-based inks endowed with maximum covering power and high opacity. It is specifically formulated to obtain intense colors and very clean tones on any surface, excelling particularly on brown papers.
Operational Advantages
- Flawless finish on dark backgrounds: Its high pigment concentration guarantees vivid and bright prints even when operating at high speed.
- Rotary press performance: It exhibits excellent machine behavior, with good stability in the ink fountain and fast drying to optimize production times.
- Guaranteed resistance: Prints offer great rub resistance, good resistance to water and wet rub, and lightfastness ranging from good to very good depending on the color.
