Discharge printing: The simplest explanation? Discharge ink
is a water based product that is formulated to deactivate
the dyes used on natural fabrics.The ink can be used to print
colours on dark garments that in the past would have
required an additional layer of white ink in order to achieve
proper opacity of top colours. Printing a straight discharge ink
typically ‘bleaches’ the fabric down to its natural colour, a slightly
off white. Discharge inks work well on fabric that is dyed with
reactive dyes, although some dyes are more resistant than
others, often those colors are in the kelly green, purple and
royal blue families. When discharged, these resistant fabric
dyes yield a more muted print that is usually a lighter tint of
the base fabric color.
