Best way if its just for a presentation is print on iron on transfers get a scalpel and cut the design out carefully and iron on, this way it wont fade at all if its not worn and just put into a portfolio.
DTG is good if its being worn lasts around 40 washes if you get a decent place before it starts to fade
Vinyl printing if its just a simple silhouette, it'll be plastic-y but it wont fade at all.
or If it is just 1 colour you can get around 10 screen printed cheap which is the best method of printing tees available.
Hope this helps man, I've working in around this industry a while so I think these are the only options for what you're wanting.
