My company is just starting to produce coffee mugs with sublimation transfers that we are printing with a Ricoh 3110. We have a small convection oven to do do most of the tranfering but we also want to purchase a good quality mug press for doing those designs that extend from the very top to the bottom of the mugs. We've been told that using a "wrap" in a convection oven will not work for "top to bottom" designs. If this is true, what is a good mug press in the market that will do this type of transfer. We expect to printing 400-500 mugs per month in the press so we need a machine that will hold up well. Any suggestions will be appreciated.
