FAQ
What is the main difference between CI and Inline flexo presses?
CI flexo presses use a central impression cylinder for consistent print quality, while Inline presses have multiple print stations for flexibility in production.
How do I choose the right web width for my flexo press?
Consider your production volume and substrate requirements. Wider webs are suitable for high-volume production, while narrower webs are better for specialized applications.
What maintenance schedule should I follow for my flexo press?
Implement a three-tier maintenance schedule: daily checks, weekly maintenance, and monthly servicing to ensure optimal performance.
Can flexo presses print on multiple substrates?
Yes, modern flexo presses can handle various substrates, including paper, film, and corrugated materials, making them highly versatile.
What is the average lifespan of a flexo printing plate?
Photopolymer plates typically last for 100,000 to 200,000 impressions, while rubber plates can last up to 500,000 impressions.
How do I optimize ink usage on my flexo press?
Use proper anilox roll selection, maintain consistent ink viscosity, and implement closed ink systems to minimize waste and improve print quality.
What safety features should I look for in a flexo press?
Look for emergency stop systems, safety guards, interlock switches, and operator protection barriers to ensure workplace safety.
How can I reduce makeready time on my flexo press?
Implement standardized procedures, use quick-change systems, and maintain proper documentation of job settings to minimize setup time.
What are the environmental benefits of using flexo presses?
Flexo presses can use water-based inks, have lower energy consumption, and produce less waste compared to other printing methods.
How do I ensure consistent print quality across different jobs?
Maintain proper plate registration, use consistent ink formulations, and implement regular press calibration to achieve consistent results.
