CMYK is the standard print colour system using four inks: Cyan, Magenta, Yellow, and Key (Black).
Sublimation
Sublimation is a printing method where special ink turns to gas under heat and embeds into polyester fibres, making the design part of the fabric itself.
DTF Printing
DTF (Direct-to-Film) is a digital textile-printing method where the design is printed on a special film and then heat-pressed onto fabric.
