Glossary
Airflow
Air is blown through the printing zone to speed up the drying process.
Back tension
The backwards tension applied to the substrate by the input spindle, which must be constant across the width of
the substrate. Too much or too little tension may cause substrate deformation and print quality defects.
Bidirectional
Bidirectional printing means that the printheads print while moving in both directions. This increases the speed of
printing.
Bleeding
A print-quality defect that occurs when...
