Logo Design Starbucks

Printing trademarks on t-shirts..?
I am interested in going into t-shirt design, and printing – mainly for business experience.
Recently I have seen a lot of t-shirts that have trademarks printed on them, such as the Starbucks Coffee logo, and also characters that I would think would have some sort of protection (like Disney) have been on a lot of company’s t-shirts recently. Does one need special permission to print such things onto a t-shirt?
ya u do need permission from the company
