Tension, Vacuum pressure, keeping the distance to the printheads constant.

Page 67 highlights

Tension Tension is applied at the input and the output side of the printer. It needs to be evenly distributed along the whole width of the substrate, thus substrate load is a critical operation. Vacuum pressure The vacuum applied to the substrate in the printing zone helps to hold the substrate down on the print platen, keeping the distance to the printheads constant. ENWW Glossary 63

Tension
Tension is applied at the input and the output side of the printer. It needs to be evenly distributed along the whole
width of the substrate, thus substrate load is a critical operation.
Vacuum pressure
The vacuum applied to the substrate in the printing zone helps to hold the substrate down on the print platen,
keeping the distance to the printheads constant.
