I pretreat fabric with Bubble Jet Set. It's very easy and not too expensive. The last one I purchased was from Walmart.com and I believe it was under $15. There is another product called Bubble Jet wash I think and it is for setting the colors and removing excess ink. It's more for printing pictures on fabric where a lot more ink is used. I've not used it on my labels and had no issues with fading. I do let my labels sit overnight or longer before ironing them and I launder my quilts before gifting them. The one time I didn't wait, I had fading issues and had to get the quilt back and replace the label. I also use 200ct muslin or better quality cotton for printing my labels.
