K I got my swatches from myfabricdesigns and these guys actually put on a color spectrum on each piece thankfully. Here's what I found:

Printing quality (in random order for each category):
High: Modern Jersey, Polyester Pongee Silk, Polyester French Terry, Silky Faille, Cotton Silk, Heavy Cotton Twill, Organic Cotton Interlock Knit, Organic Cotton Sateen, Cotton Poplin, Basic Combed Cotton
Medium: Performance Knit, Interlock Blend, Silk Crinkle Linen (good colours but possibly too see through and with lines visible), Linen Cotton (same as previous, less see through), Silk Crepe De Chine, Cotton Voile, Premium Cotton
Low: Quadri Performance Sport Knit (lines throughout), Polyester Slub Jersey, Polyester Crepe Jersey, Faux Linen Slub Sheer, Faux Linen Slub (bright colors but visible lines bother me, might not for other people), Flame Retardent Faux Linen (by far worst), Faux Linen Canvas (holes make blurry image), Organic Cotton Jacquard
Using this info, I think there are a few top options.
Modern Jersey - Colours are sharp, well defined lines, very little bleeding of colours, not see through at all really. Fabric is very stretchable if that's something you want, which obviously hurts the print quality. Breathability is high and one of the better for good quality print options.
Polyester Pongee Silk - Basically the same description as Modern Jersey while edging it out ever so slightly in light grey colour as well as breathability. Black not as black though and colours not quite as bright. Medium Stretch
Organic Cotton Sateen - Good colours and black level, odd print shape that looks like the fabric moved in printing that is scaring me away from this one.
Basic Combed Cotton - Really good print quality, colours come out great and next to no bleeding in the text and colour wheel with good black levels. No stretchability. Little bit more see through fabric with slight visible lines up close but not at arms length. Slightly worse breathability, but at the higher end of the medium level for it.
Haven't decided which way I want to go yet. Picture shows the 3 main options IMO.
Not entirely scientific test number 2, i played a movie on my phone and covered the speakers and i honestly didn't really notice a difference between most of the fabrics, outside of the least breathable fabric and even that wasn't a huge deal.
In the end I went with Basic Combed Cotton, mostly because the lines come out crisp and has the least amount of bleeding/blur. I also wanted to get a fabric that doesn't stretch because I don't want to distort the image. Who knows if that's the right call but I think it should perform well enough.
***BONUS*** While these fabrics are already pretty cheap, it is worth noting that they are actually having a sale until the end of Sept for 25% off when you use the coupon code HIP so it comes in even cheaper than that if you order soon.
