What Type of Ink is Typically Used in High-Speed Flexo Printing Machines?

This article explores the essential types of ink used in high-speed flexo printing machines—a key concern for professionals seeking optimal print quality, speed, and regulatory compliance. We cover industry standards and application-specific tips for choosing the right ink for flexo printer operations.

Common Ink Types in High-Speed Flexo Printing

- Water-Based Inks

- Widely used for corrugated packaging and paper substrates.

- Offer environmental benefits: low VOC emissions and easier cleanup.

- Dry quickly on porous substrates—ideal for high-speed machines (Source: FTA Technical Guidelines).

- Solvent-Based Inks

- Popular for flexible films and non-porous substrates.

- Deliver fast drying speed, crucial for high productivity.

- Provide excellent adhesion and color strength; however, require good ventilation (Source: Printing United Alliance).

- UV-Curable Inks

- Cured instantly under UV light, boosting press speed.

- Suited for labels, shrink sleeves, and specialty packaging.

- High chemical resistance and print durability with minimal environmental impact (Source: Ink World Magazine).

Key Factors for Ink Selection in Flexo Printing

- Substrate Compatibility

- Choose ink based on paper, film, foil, or board material.

- Improves adhesion and prevents smudging or defects.

- Drying & Curing Needs

- Proper drying is essential for smudge-free high-speed production.

- UV inks enable immediate finishing, increasing overall throughput.

- Regulatory & Environmental Compliance

- Water-based inks help meet strict VOC and food safety standards.

- Stay informed on regional environmental regulations (Source: European Printing Ink Association).

- Cost Efficiency

- Balance ink performance with total production cost.

- Water and solvent-based inks are cost-effective for large runs; UV inks offer efficiencies for specialty prints.

Industry Data & Trends

- Over 75% of packaging today uses either water- or solvent-based flexo inks (Smithers Pira, 2023).

- Global demand for UV-cured inks in flexo is expected to grow 8% annually to 2027.

Practical Tips for Flexo Printer Professionals

- Regularly maintain ink delivery and drying systems to avoid print defects.

- Test inks on actual substrates before large production runs.

- Keep up-to-date with advancements in low-migration and sustainable ink technologies for future-proofing operations.

High-speed flexo printing relies on the right choice of ink to meet industry standards for speed, quality, and sustainability. Understanding ink attributes and matching them with your equipment and substrates ensures optimal results for every print job.
