Only option is an Oven if its regular work.2-300 mugs /week
One person, 72 mugs per hour.
216 MUGS 3 HOURS
324 MUGS 4.5 HOURS
That is how long it takes me anyway.
This does not allow for warming the oven which takes about 10 minutes.
Cost of a decent oven about £300
Mug wraps £4.00 ish on ebay - you need about 72-96 ideally
Decent set of gloves
So about the same price as 1 twin press yet higher speed and A LOT less hassle on top to bottom print, plus you can get A LOT closer to the handle (about 8mm)...
