Just a word of caution if you are considering the sublimation route, make sure you have enough demand/business to do it. Materials, ink, substrates, and equipment can quickly eat up any profits. We have a Epson 4800 that was purchased for sublimation, constantly had to clean the heads (read buying lots of ink) and most of what we were selling were one or two at a time, so fairly low sales, in relation to time spent talking to customer, design, and production. When the last set of sublimation ink ran out, we converted the printer back to regular inks and plan to attempt to sell it, and the mug press (both heavy so expensive to ship). Did a count on the printer for number of prints, and divided the amount of ink purchased for it and came up with an astonishing cost of $2.30 average cost per sheet of paper printed.
Early this week I put the Mug press on Craigs List, had one guy call who did not know anything about sublimation, and the other call was from another shop who does sublimation and lots of engraving, he wanted to know if I was getting any bites-------
because he was getting out of the sublimation business because he was unable to make any money in it either.
Bottom line, keep your eyes wide open, I am sure some folks are making money, just be aware of all the downsides to it as well.
