WB-1 Discharge Ink System from Image Technology is an aqueous, water-based, screen-printable ink that reportedly produces exceptionally bright, vivid, opaque-colored prints on dark fabrics with a very soft hand. Image Technology says WB-1, when used properly, effectively displaces the dyes in a properly prepped garment, allowing the printed color to take the place of the fabric’s dyed color. WB-1 is formulated to be odor-free and for an extended shelf life after activation. Image Technology, 1380 N.
