Measurement of mark distances in the printing press
Monitoring of the pattern repeat lengths is crucial for a printer. Tension of the machines and the stretchability of the material makes it difficult to meet the requirements for correct mark distances. The ELOVIS Laser-Encoder system μSPEED-RL system offers non-contact and continuous accurate inline measurement from the first meters.
Typical application data:
- Path Velocity: typically up to 1,800 m / min
- Mark spacing: typically from 50 mm to 1,000 mm
- Measurement accuracy with repeat length measuring system μSPEED-RL: typically +/- 0.3 mm
- Amortization: 3 months, optional: integration in machine control
Material examples:
- transparent film, high-gloss film, food film, packaging film, furniture film, …
- PET film, PE film, PP film, PVC film, PS film, PLA film, …
Machines equipped with non-contact length measurement:
- Printing machine, roll printing press
- roll cutting machine, roll cutter, cross cutter, lengthwise cutter
- Winding machines, rewinder, re-roller, doctor roller
