Light on Dark

Light details on dark backgrounds can quickly disappear if not done properly. White or light colors, which have no ink on them, leave pleanty of space for dark colors to move in. The textile fibers soak up ink, spreading it along their length (just like a red wine stain), and suddenly your light-colored details have vanished into the background color.

Make any thin, light-colored details a bit thicker than normal in your design, to keep them visible

The thinner the material is, the more risky such fine details are. For example, on delicate Batiste fabric the spreading of black and dark ink is the most extreme becasue the cloth is so thin even a tiny volume of ink must travel sideways instead of inwards, like on blotting paper. To deal with this, make your darker background a bit lighter, for example; use dark grey rather than black when printing solid silouettes or text on a white background, or choose a thicker material which will prevent the ink from bleeding, such as quilting-grade cotton or cotton sateen.

Increase the precision of your design by using a less dense color or a thicker fabric.
