Opacity
The degree to which a DTF transfer blocks the garment color from showing through. High opacity white ink creates a solid base that makes colors appear identical on both light and dark fabrics. Measured as a percentage — 100% opacity means no garment color shows through.

A layer of white ink printed beneath the colored design on DTF film. The white underbase ensures colors appear vibrant and opaque, especially on dark-colored garments. Without it, colors would appear transparent or washed out. The white layer is printed after the CMYK layers in DTF.
Specialized pigment-based ink used in DTF printing to create the opaque white underbase layer. White DTF ink contains titanium dioxide particles that are heavier than colored ink pigments, requiring regular agitation or circulation to prevent settling and clogging.
