DTF transfer by garment size is redefining how printers preserve color fidelity as designs scale across diverse garment sizes, forcing studios to rethink ink behavior, substrate interaction, and in-line quality checks so that a medium on a tee, a large hoodie, and an extra‑large jacket all read as a cohesive family of colors.Within this framework, DTF color management becomes a size-aware discipline that accounts for fabric content, weave density, base shade, pre-treatment variations, and even post-press behavior, so operators can predict how ink sits on cotton, polyester, blends, and high-thread-count materials, on every session.
