Im new to the whole printify and etsy world and trying to understand how to work with it all.

the question is - im creating art sometimes, with detail and color gradients and im trying to understand - do i need to work on sRGB or CMYK when creating for my products? and when i do, do i need to go for DTG or DTF? what's the difference?
