So, you’ve got a paper converting line that really flies, maybe running at speeds like 700 or even 850 meters per minute. That’s incredible speed. Now, you need to add a printing step directly into that line, probably to print things like the ‘PAP’ recycling symbol, batch numbers, or other legally required information. This means adding an inline flexo press or a flexo printer. But how do you pick the right one when things are moving so fast?
Think of your paper line as a high-speed train. The printer you add can’t be a slow local train; it needs to be just as fast, or it will cause delays and problems.
Here’s what really matters when choosing that printer:
Speed matching is king
This is the absolute number one priority. The flexographic printer must be designed and built to comfortably handle the top speed of your converting line (700 m/min or more). If the printing machine can’t keep up, it becomes a bottleneck, slowing everything down or causing poor quality prints.
Built tough for the long haul
A printing machine running at these speeds, often 24/7, needs to be extremely robust and reliable. You can’t afford frequent breakdowns stopping your production line. Look for solid construction, industrial-grade components, and designs made specifically for continuous high-speed operation.
Clear prints, even for simple symbols
Even if you’re just printing a ‘PAP’ symbol or batch code, clarity at high speed is crucial. The flexo printer must offer precise control over ink transfer and printing pressure, ensuring consistently sharp and legible results without smudging or variation.
Easy integration and fast changeovers
The new inline flexo press must physically fit your existing line and integrate smoothly with your control systems. Also consider how easily operators can change printing plates or settings when you need to switch to different codes or symbols. Quick changeovers reduce downtime and improve overall efficiency.
Choosing the right inline flexo printing machine isn’t just about finding one that can print — it’s about selecting a flexographic printer that becomes a seamless, fast, and reliable part of your high-speed paper converting process, ensuring those essential symbols and data are printed cleanly without slowing you down.
