Spec
Stroke Weight
The thickness of a line or outline in a design, measured in points or pixels.
Definition
Stroke weight is the thickness of a line, outline, or path in a design file. It is measured in points (pt) for vector art and pixels for raster art. Stroke weight matters in transfer production because lines below a minimum thickness cannot be cleanly reproduced. The polyamide powder step in DTF requires enough ink width to hold adhesive. Raised UV requires enough surface area to build cured layers. At Long Island DTF Printing the minimum recommended stroke weight is 1.5 pt for hairlines and 2 pt for text outlines on a dark garment. Strokes below 1.5 pt may break apart at the powder step or fail to bond.
