We have recently bought a UK Press - Heat Press (Model HP5IN1) to transfer our logo onto company shirts. We have a Laser Printer (Samsung C9301) and an Inkjet Printer (HP Envy 4524) and have conducted test run transfers on Inkjet Heat Transfer Paper (Light/Dark) and Laser Heat Transfer paper (Light/Dark). I have attached picture of the transfer trials on the t-shirt but my concern is that when we try to transfer our logo onto our black work shorts the image wont be defined. Could you please advise what the best material and method would be to transfer image onto coloured fabric. The fabric for both t-shirt and shorts is 100% polyester.
