DIRECT-TO-FILM & TEXTILE DECORATION
DTF Halftone Screen Ruling & White Ink Choke Vector Guide
Direct-to-Film (DTF) digital printing combines CMYK water-based pigment inks with an opaque white underbase printed onto a PET transfer film, backed by hot-melt TPU polyurethane adhesive powder. High-quality DTF production requires choking the white ink layer to eliminate unsightly white border fringes and converting raster gradients into mathematical vector halftones for soft garment drape.

1. White Ink Underbase Choke Settings
Because white ink viscosity differs from CMYK pigments, mechanical printhead registration tolerance requires choking the white underbase mask inward by $1.5 - 2.5\,\text{pixels}$ at $300\,\text{DPI}$ ($0.12 - 0.20\,\text{mm}$). This ensures zero white ink bleeds past the color graphic boundary.
