1. Long IPG turn off time results in two aftermaths: 2. The galvo head may need to decelerate for a long time, resulting in low marking speed. 3. When galvo head delay is set to short for high marking speed, the slow turn off pulse train leaves a irregular turn around ghost trace and sacrifice the marking contrast. Marking Results
