How many impressions can it do per hour?

It all depends on you and / or your operators. For tag-less tee shirts the average is about 1000-1500. Least we have seen is about 700 per hour and the most we have seen is 2150 per hour. For promotional products it is much easier to load so this means they are averaging over 1350 per hour. On an Average 10 hour day (including breaks, lunch, and other etc) our customers are producing 10,000 units.
