Ok, I took some time to think about things and I still want to do this.
One of the reasons is I read that the Hand is better than anything (well except sublimation which has NONE), and I really think good hand makes the shirt. I use to print shirts for my old business, and we paid for the entire set up, shirts and supplies in 1 weekend. I also printed stuff for local clubs I was in, basically getting a better shirt, full color for the price of the cheapest cotton T and one color printing.
I don't mind spending more on a printer if that will make my experience better. I am going to dig into this next. Also, the XP15000 is $250 refurbished and from my experience Epson just sends you a replacement printer if you have the slightest issue with a refurb. So I kind of wish they still made the P400 as that seems to be the popular pick, but I will look around.
The biggest expense is a good press, and I have that.
If I need to print every day or every other day I will just print and cure the glue and not press the image. This is in my room with my 3d printers so I am in there a lot anyway.
I am going to grab a tube rocker from the lab, can I not just take the sponge out of the white ink cart and set it on the rocker on a timer to keep the ink mixed?
