Abstract
Provided herein is a method for forming an image on a dyed synthetic fabric, using a dye-discharge agent, the method is effected by printing an ink composition on the fabric and applying a dye-discharge agent essentially on the same area of the ink composition, wherein applying the dye-discharge agent is effected while the ink composition is still wet (uncured), prior to a curing of the image, and followed by curing the fully formed image, whereas the dye-discharge agent discharged the dye that migrated during the curing step, but not the dyed fabric.
Claims9
A method of printing an image on a pre-dyed synthetic fabric, comprising:
- (a) applying at least one ink composition on the fabric on at least one first area, so as to form the image;
- (b) applying a dye-discharge agent on at least one second area of the fabric, said at least one second area is at least partially overlapping said at least one first area;
- and
- (c) curing the image,
- wherein:
- said curing is effected by heating said at least one ink composition that forms the image;
- the pre-dyed synthetic fabric releases a dye upon said heating;
- and said dye is dischargeable by said dye-discharge agent when released from the fabric upon said heating.
(canceled)
A method of improving the whiteness of a white layer printed on a pre-dyed substrate, comprising applying a white ink composition on at least one an area of the substrate and applying a dye-discharge agent essentially on said area, wherein the pre-dyed substrate releases a dye upon heating the substrate, said dye is dischargeable by said dye-discharge agent when released from the substrate, and said applying said dye-discharge agent is effected prior to said heating of said ink composition.
