Almost entirely retired I imagine. Belt printers/AOP machines practically non-existent here. As said above, no matter the machine, the labor/ROI studies conducted deemed the process is; while highly desirable for some, simply way beyond cost effective. And switching out pallets can be hard on the machines (indexers) over time. Most in the past were designated as dedicated lines so you really needed steady sales to keep them going which almost never happens. Same with flock. Great ideas but impractical and not a wise investment here in the US IMO.
And don't forget to get a super over size DTS or upgrade your film output device
