For the first time a newly developed discharge ink supports ink-jet printers. This allows printing on dark color T-shirts. Gradations are also perfectly expressible, which expands characteristics of an ink-jet printer. TP Ink is safe and contains very low levels of formaldehyde. It does not impair air permeability or the water-absorbing properties of fabrics. Printed fabric keeps a very pleasant feel. TP inks now feature more vibrant colors, and better color fastness for improved washability. Because of a special binder, only heating after printing can complete the job. Note: Color fastness to washing differs according to the garment materials, etc. Please confirm the color fastness yourself by washing finished garments. Printed fabrics contain very low levels of folmaldehyde; please don't use it for baby goods. NOTE: This product requires Firmware Version 2.20 or higher.
