Printing both sides (fiber + PE) of polyboard
High severitySymptoms
The second side fails although the first ran fine; adhesion or registration lost at the turn
Probable causes
- Each side is a different substrate (absorbent fiber vs non-porous PE) demanding different ink, dampening and drying
- the turn adds curl and dimensional change
- PE treatment decayed while the first side dried
