1. What are the current challenges for the die-cutting of labels?
Martin Stierle: In my opinion the top three current challenges for the die-cutting of labels are:
- Grammage and thickness of substrates getting thinner and thinner
- High speed converting 150 m/min (492 fpm) plus
- Short delivery times for flexible dies 8 to 48 hours
- We are living in a digitized production world, in your opinion, which system is the most suitable for the modern single-pass label printing (rotary/laser) process?
Martin Stierle: Which system, in your opinion, is most suitable for the modern single-pass label printing? This depends on the process as well as the application. For offline finishing of digital printed labels, around 97% of all converters use conventional fully/ semi rotary devises. In my opinion laser cutting is just not at the right level and still needs time.
- In general: what are your preferences for certain applications? (Semi) rotary die-cutting or laser die-cutting?
Martin Stierle: See point 2
- Laser die-cutting is a rather new technology: where do you see the opportunities and limitations of this process?
Martin Stierle: Regarding laser die-cutting and its opportunities and limitations there is a few points to consider:
- -Perfect fit to digital printing in general
- No costs for knives
- No waiting time like for flexible dies
- Limitation in speed
- High investment for laser unit
- High maintenance costs for laser
- Not enough “laser friendly” substrates available
