Hi Mac921,
There are several factors that can contribute to imaging speed.
The first is the plate itself. Depending on the speed of the plate, you may or may not achieve the rated pph. All platesetters base performance on a fast plate such as our Thermoplate PN. Not all plates are rated as fast and this would effect productivity.
There are also two generations of Suprasetters, the current one being the Generation II. They have difference performance levels.
If you can PM me you name, location, phone number and company, I can have someone follow up with you to review.
Regards,
Mark
