Application

• Applicable to blends and acetate fabrics

• Better UV fastness than dye-based ink

• Open new application to non-textile

substrates, e.g. non-woven, PVC,

wallpaper, etc.

• Low barrier to entry investment

economics

• No steaming & washing process cost

• No post-treatment capital investment

• Reduce defect of color toning during

steaming (reactive)

• Reduce time to market

The Case for Pigment Inkjet Inks

Economic

• No waste water discharge

• Less power consumption

• No hazardous chemical used
