Hello Clay
I can't help I'm afraid. This post was very early in my T-shirt printing investigation phase, and I ended up concluding that I preferred screenprints to heat press printing.
I subsequently had several batches of designs screenprinted by Rodney's company, and was very impressed with the quality and service. It was after this experience that I decided screenprints were definitely the way to go for me.
In the meantime, I've opened a couple of POD stores (Printfection), and ordered a couple of my designs to see how they turned out. Very good, as it happens. I still prefer screenprints, but for some stuff, like intricate multi-coloured designs, I think good direct-to-garment digital prints can even be the best option.
To summarise, heat presses are no longer of any interest to me. Screenprinting would be my first choice, and GOOD QUALITY DTG next...but not much in it between those two in terms of faithful reproduction of your design on a T. Thus, between these two printing modes, it comes down to personal preference IMO, and that's about it.
Good luck, whatever way you choose to go.
Cheers
Ross
PS: There are others who are far more involved in the T design business than I, so bear that in mind in considering what I have said here.
