DISCHARGE PRINTING

WHY DISCHARGE PRINTING? Printing on light fabrics with transparent inks allows to obtain prints with a very soft final touch. Usually, this is not possible onto dark fabrics, since prints with opaque inks has a rather stiff touch.

The option is DISCHARGE PRINTING


DISCHARGE PRINTING STRONG POINTS • Highest opacity on dark substrates • Extremely soft touch • Very bright colours • Anti-foil effect


DISCHARGE PRINTING PRINTABLE SUBSTRATES Discharge printing takes place on fabrics coloured, usually with dark tones, with "dichargeable" dyes

In the printed areas the background is destroyed by special reducers, leaving natural fabric colour areas (or coloured if in the paste is added a pigment as well)
