White Underbase
Definition
What is white underbase?
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.
