What kind of custom printing technology do you use when you need to print 1320 units (polyester t-shirts) with a full color logo on the front and a custom name and number on the back? Heat printing. Thanks to a combined effort between Stahls’ Transfer Express, who printed and delivered over 1300 multi-color transfers in less than 2 days and the heat printing team at Stahls’ Decorating Fulfillment Center, the custom printed Under Armour shirts worn at the Tazon Latino Celebrity Flag Football Game on February 2nd were a huge success.
