source for Digital Transfers

Help needed. I have used stahls for years to purchase full color digital transfers. The issue I am having is small areas or fine detail then stahls has to print a border to make them work. This looks tacky and I am sure there are better options out there. What are companies doing when they use heat transfer labels for the shirt labels? Any suggestions would be greatly appreciated. I need to be able to order a full color logo with no borders or outlines to use as a transfer on performance products.

thanks
