I have a potential customer that recently came to me wanting a design they put together on the CustomInk website. He asked if I can print that design. My question is how do I hunt down copyright holders of the clipart images they host on their website and if it would even be worth it? Its a small job of 15 shirts. I found the font they used however the licence is 160$ and only comes in a 6 pack with 5 other fonts.
