[citation][nom]gwolfman[/nom]I agree with Calvin_laing, won't the ink fade and/or wash out?[/citation]
If you use regular printer ink? Absolutely. Sunlight would bleach it and washing simply remove the colours. If you'd want to show up on, say, a party with an original shirt, you could take an old white shirt and print something on it, but more than that is beyond the capacity of regular ink.
But maybe there are companies selling waterproof high quality printer ink? But if there are, it's probably so expensive it's cheaper to find a local business that prints shirts.
Haha I could thing of some prank job that you could do with that. You could put porn picture on the back of the shirt and arrange something that the person would not realize what is on the back and then let him go outside and watch bystander. LOL
This seems like a great idea if you're somebody trying to make original shirts (i.e. bands, artists, entertainers, business owners). If you're willing to put in the time in design and troubleshooting, it could pay huge, otherwise it still isnt very expensive to have a screen printer print your shirts in bulk. The ink on the market for home cloth printing is pretty pricey.
