Can We Print On Garment With UV Ink?
Can you? Maybe. Would I suggest it? No.
There's some talk that you can, and you don't need a pretreatment. While that may be true, it opens a whole other can of worms. The inks that are used in all UV printing, are fairly similar. The concern with UV inks is that they contain monomers, and monomers are what actually make it set. If those monomers are not fully set, you run the risk of people having skin irritation. And that's certainly something that;s a bigger concern with youth and children's shirts. You need a flexible UV ink. Generally flexible UV inks work well on items that flex, however they don't work well on items that don't flex. So if you buy a printer based on doing t-shirts, you've got to choose – do you want to do flexible or rigid? It's not something you're going to switch between. Swapping out inks is a major expense, a major time waste.
The other thing is that it doesn't look good on t-shirts, and certainly doesn't look good on cotton.
If you want to get a UV printer, it has to be kept in a ventilated area. This is not a back bedroom business. It's a big machine, and the UV ink smell affects people differently. If you're going to be working around it all day, especially if you're overly sensitive to smells, you need to make sure it’s ventilated.
