Leather, fabric and paper. Things people make: t-shirts, hoodies, tote bags. From the sources at the end, checked October 11, 2026; we haven't tested it ourselves.

What it needs

Desktop UV printers
Limited Makers say UV ink is not the route for garments; printing cotton needs a fabric head (DTG or DTF) such as xTool's O1 Omni UV + DT edition or Longer's ePrint UV + DT combo. [1] [2] [6] [7] [8]
Primer or adhesion promoter
Not stated
White ink
On dark or clear. In xTool's DTG workflow, dark garments get a white underbase on white pretreatment; light garments use color pretreatment. [3]
Flat or curved
Flat bed. Garments sit on a tray with a magnetic frame, smooth and wrinkle-free (xTool). Longer says keep the fabric flat. [3] [8]

How long it lasts

Dishwasher
Washing: xTool says DTG prints can have good wash durability when the garment is pretreated, printed and heat-cured. The sources give no wash results for UV ink on fabric. [2]

What goes wrong

  • xTool says UV direct printing is not recommended for fabric; fabric inks and transfers are made to flex with the textile.
  • eufyMake says flexible white UV ink does not bond well with cotton or fabric with loose fibers.
  • Rigid white UV ink cracked within 5 bend cycles on cotton canvas in xTool's test; xTool describes the cured film as stiff, like a sheet of plastic.
  • Thin fabric lets ink seep through onto the garment tray in xTool's DT mode.

Before you print

  • xTool lists fabric printing for its UV + DT edition only; its Single UV and Dual UV editions do not do DTG.
  • Use garments with at least 50% cotton for DTG on the O1 Omni (xTool).
  • Pretreat first: white pretreatment for dark garments, color pretreatment (diluted about 1:19) for light ones.
  • Pre-press, then heat-press again after printing (xTool: 150 C, 60 s, 50 kg) to cure for wash durability.
  • xTool says a DTG print feels softest on light garments without a heavy white underbase.
  • Longer recommends DTG ink on 100% cotton for direct garment printing, or DTF ink with transfer film for a wider range of fabrics.
  • Keep the magnetic frame off seams and stitching.
