Inkjet
Inkjet printers are not capable of printing white. So, anywhere that the image requires white, the garment's existing colour shows through. The mirror of the image is printed on the paper. When it is transferred, the result is the mirror of the mirror (the original) results. Inkjet transfer paper for dark garments is covered with transferable white ink. For dark garments, the image is printed without mirroring.
Washability for inkjet transfer paper is not as good as a screen printed shirt.
