Think about the size of the work that you want to do and make sure that the press is large enough for want you want to do. There are 5 general groups of sizes and each group has its advantages, depending upon your needs. They are:
Very Small: 4x6, 6x6 and 6x8 presses are perfect for small items like baby clothes, awkward items like tote bags with seams (they can be opened and pulled onto the press) and even very large items where heat is only needed in a small area. This class is usually referred to as "Label Presses".
Small: 9x12, 11x15 and 12x14 presses are excellent for maximum portability (and very low price), 8.5" x 11" heat transfers that you print, patches and other small items. Be aware that most preprinted heat transfers are larger than the heater block on small presses.
Medium: 16x16, 15x15 and 14x16 presses are large enough to do the work for most decorators. They offer the advantage of much more power (wattage - important if you are doing a lot of repetitive pressings) than the small presses, a much cheaper price than a comparable 16x20 heat press and the ability to press the typical preprinted heat transfer.
Large: Any type of 16x20 press is considered to be a "large" heat press and very few have a need for anything larger. This size of t shirt heat press easily does 11x17 transfers that you print on an inkjet printer, the largest preprinted transfers offered on the market, large names and numbers on garments and multiple small items. Salespeople in most companies automatically offer this size because it is a bigger commission for them but you need to carefully consider if you need something this large.
Very Large: These monsters range in size from 18x20, 14x36 and 20x25, up to a gigantic 40x64. If you need a very large press, call us and we will help you choose which one you need to be more efficient.
