The Original HP 745 Chromatic Red Ink Cartridge (F9K00A) contains 130ml of vibrant red pigment-based ink designed to enhance the colour range of print projects produced with DesignJet printers. This ink is optimised for high-impact applications such as point-of-purchase displays, signage and photo-quality prints, delivering saturated reds and smooth gradations that elevate visual appeal. Formulated as part of Vivid Photo Inks, it provides durable, water, scratch and fade-resistant results that can last for up to 200 years under optimal conditions, ideal for archiving or long-term display. In combination with HP's intelligent cartridge and printer systems, the Chromatic Red ink helps maintain consistent colour performance across long print runs, while quick-drying properties minimise smudging and allow for fast handling and finishing. The cartridge's 130ml size offers a productive balance between capacity and cost.
